The trimmer line is made out of nylon which is hygroscopic and in order to process nylon (extrude it) the material must have the moisture dried out of it pre-process. Then in order to make the nylon less brittle, the moisture should be re-introduced into the line/part that has been molded/extruded. With nylon being hygroscopic, it will absorb the moisture like a dessicant. I have worked in plastic injection molding for 30 years.
Back when I was working at GM, I had a job that involved pushing a plastic nut into a hole in the firewall, using an installation tool that was basically a long steel rod with a rubber knob on the end. The nut was for screws that secured the shifter cables as they passed through the firewall. The nuts became extremely difficult to install after a while, actually giving me a “ tennis elbow”. They tried heating the nuts with a heat lamp but it didn’t work. Then one of the engineers called to supplier and they told him the nuts required some watering from time to time. I always wondered why they came wrapped in a plastic bag inside a cardboard box! So whenever a new box of 10,000 nuts came in I dumped a cup of water in the bag. Problem solved!
I dont know about the Trimmer line, But i did soak Myself with Beer one Friday night and went to work on Saturday and i can tell you that Trimming was killing me all day! (This also is just Opinion and not Science tested!)
I leave mine in a bucket with a tiny hole for the line to come through in my open trailer to keep direct sunlight on the line. Every so often I put some water in the bucket to build humidity in said bucket. I do notice the line doesn’t fracture or split as much
Never had a problem with line breaking the first summer i had my stihl trimmer. After the first winter string broke immediately every time after being in the garage for a season. Soaked it for 2 hours. And been soaking it for about 12 hours prior to use. No breaks. Use all string
It returns the elasticity to the line. A product engineer said for home owners he uses a zip lock bag with a tablespoon of water to allow it to be in a humid environment. folks go not have to get crazy about it.
It's still good to soak new line just to be on the safe side. Because some of this line sits in very hot warehouses for no telling how long till it gets shipped to the suppliers all over the US.
Hi, really interesting, but how long does the “water’s effect” last? For example, I let the line soak for two days, than I feed the trimmer head. Than, how long can the line stay in the head before I have to soak it again? I hope I’ve explained well my question. Thank you.
Great video Mr. Chip. Never knew any plastic could be “revitalized” by soaking it in water. Learn something new everyday. Thank You for the information. Have A Productive Day! 🛻🚤🏖️
The biggest thing is store it in a cool place. I used to keep mine in a small outside utility building, got hot as hell out there in the summer, and my line would sometimes break off up in the bump head which was a beech. It becomes brittle. Keeping it in the sun, same thing. Think dark corner of garage, basement, what ever, just keep out of the sun or heat the best you can. Soak it, then put it back in the sun/heat, you have not accomplished chit.
Nylon (not just trimmer line) likes to have moisture in it because it makes it tougher and more resistant to impact (though technically it does reduce the tensile strength slightly). However, you can't process nylon with the moisture in it because it forms bubbles when you try to melt the plastic. Degrades it, too. So they dry it out first, manufacture the trimmer line and may or may not reintroduce the moisture afterwards. Nylon is really hygroscopic, though, so I suspect this only matters in really hot and dry climates.
My first trimmer mower over 20 years ago, you bought the heavy line as straight pre cut sticks in a clear poastic tube with a tight cap that had a sponge in the tube that you kept wet.
I recently did this with a spool that has been sitting in the garage for several years. It’s been a week. Yard day is coming up so I’ll see if this actually makes a difference.
No, you just never understood what plastics were what and what applications each one excelled at. Or which ones are hygroscopic and which ones are hydrophobic. Nylon has ALWAYS been a hygroscopic plastic. Which is why it's not used for water tanks, 5 gallon buckets, jugs, etc. That's typically reserved for hydrophobic plastics like polyethylene or polypropylene, 2 plastics you also wouldn't use to make string trimmer line.
@@jaywelker5566 there again i understand the english language and if i was to make a coat made out of either type i could still label it water resistant and id be exactly correct in doing so............
@@rustyshepard9659 His point was that they have been water-resistant, mostly waterproof, so there's no point is using verbiage that implies they weren't at some point in the past. What has changed is our use of materials that are more resistant to UV degradation & typical wear & tear or longevity of the materials themselves. Trimmer string by Stihl is likely one that has more plasticity or is more malleable, thus isn't as hard until it's dried out fully, since the harder it is, the more brittle it is. Think of acrylic paint to a certain extent.
@@Gaming_Biker ok i will play along i asume if i lived in a arid area like the desert south west it might make a bit of a difference but hell how much would i really need to weed wack in the desert south west now if i was from the more humid mid south such as where i currently reside its almost 98 % humidity outsi de has been raining every other day now for 2 months im guessing my weed wacker line doesnt need a good soak as the naterual its made of probably wont leach , evaporate lose to much moisture when you can cut the air with a knife im curious though how hot and dry does weed wacker line have to get before it becomes to brittle to be effective my degree in farm business management would suggest probably long after all afore mentioned weeds that needed wacking have since shrivled up and died due to lack of water.
Yep, soak it. I've got some trimmer line that I found in the shop that was close to 20 years old. Put it in a bucket of water for 2 days, it works as good as new.
Polymers are hard because of their molecular structure. To make them "plastic" a plasticizer which is essentially a solvent which is volatile is added. The volatile off-gasses causing the polymer to return to its hard and brittle structure.
Not really for stuff like nylon. Its usually heat extruded, so it has to be dried out prior to extruding otherwise the water will boil causing it to come out foamy and useless. Then they re-hydrate it to return it to its original flexible state. That water will sometimes evaporate out of the plastic if left in an extremely dry or sunny environment, making it brittle. In most humid climates though you never really have to worry about it. I live in indiana where its 80%+ humidity most of the year so its not usually a problem here but somewhere like California or Arizona its very arid and your line will dry out just sitting around normally even without being in direct sunlight.
@@austinsparks4561 Nylon is given different properties by blending it with other polymers. Pure nylon is soft so it would be my guess that it is not suitable by itself for trimmer line.
I spray mine with würth 2040 ultra from new and get great results from it, dry line just shatters imo. Also i find the twisted line way better than the smooth type.
I find the same thing with the twisted star-shaped trimmer line. I've heard a couple of "professionals" claim smooth line runs better from the spool and it doesn't tighten up. From years of personal experience, I've had the exact opposite experience.
I would say that if you buy in bulk & keep a few rolls on your truck & constantly exposed to UV, you might need to think about this. However, I've never seen rolls stay long enough to justify this type of treatment, so unless Stihl or another brand indicate that the string breaks down quickly, like weeks or months, due to UV exposure, I wouldn't worry about this. Not saying it doesn't or can't happen, but I don't think people will go that long to see a noticeable problem.
Can't they just make a line that doesn't need to be soaked? What if I'd like to use it today, not in 24 hours? I bought new line, used it for about 8 minutes, it melted and broke off inside the spool. It wasn't on concrete or asphalt.
The lines in question in this video do not necessary 'need' to be soaked. Rather, it is 'recommended' to soak them to slightly regain the lost moisture in them.
I agree... I store my polycut blades in water... makes a huge difference in their toughness. If they get "dry" the become noticeably more brittle and break much easier.
Damn, I should have looked a lot closer on the label of my old big spool of Stihl trimmer line - I gave it away to a friendly small landscaping business owner: the next time I see him I will remind him of this tip on re-moisturizing the dry-rot trimmer line. THANKS
I've got the Echo 2620T running Copperhead Vortex. 095. The line actually fuses together in spots on the spool. Heat? The shaft does get pretty hot down there. What can I do? Awesome $500 trimmer easily rated EF1 on tornado scale. But its driving me crazy.

Seems like yes from brand new it would be a good idea (sitting around for who knows how long) and maybe if it has sat around in the garage or shed for a while. Makes a lot of sense for pros that have it sitting on the thuck (maybe just for an hour in water since you load more).
nylon absorbs significantly more moisture than PE does. PE, PP and PVC are hydrophobic plastics, Nylon does not fit the same designation and it's not used for making water containment vessels for many of the same reasons (like PE or PP) Nylon/PA6 is classified as hygroscopic.

I wish I would have known that when I had some Husqvarna line that was super brittle and I bought at a lawnmower shop. I don't know if I threw it away,it was super brutal though and disappointing because it was like you know $10 a donut of it. now that I know I'm going to take my old line and try this.
Yes it it good for it BEFORE it cracks. that way it stays hydrated and WONT crack.. duh.. that guy on the phone is clueless... and.. soak in in glyphosate and it will kill the weeds to are cutting as well.. :)
Is this fuckn satire? Used to do landscaping for a living and we never soaked line 😂 heck even now I’ve had the same roll for 4 years now that I’m no longer doing other properties and it’s just fine 😂
Nylon does lose some of its flexibility when it dries out, so this is no myth. It loses/absorbs water quite slowly though, and hydrated nylon does not feel wet or moist. If you kink the line and see it easily makes damage then it's likely too dry. Unless your line is already dried up its enough to keep them in a sealed plastic bag away from direct sunlight. That's a fair bit more practical than having large containers of water sitting around. Especially since it can easily foul over time.
@@mainstreetmower Joking of course. Trimmer line is a copolymer. When it dries out and gets brittle, it's not losing water so soaking it in water is just getting it wet on the surface. Considering that the tip end of of the line is whizzing along at 600+ miles per hour and being literally melted away from friction with rocks, concrete and chain link fences, I doubt seriously that water does anything at all. If it makes you feel better, go ahead and soak your line.
@@jaydee5156 Check "The Materials Analyst, Part 85: Fixing brittle nylon product with water"...nylon holds 1.5-2% water by volume (finished product). "Moisture acts as a plasticizer in nylon and therefore reduces strength and stiffness properties but increases elongation and toughness. In general, as moisture content rises, significant increases occur in impact strength and other energy absorbing characteristics of the material," from Amcopolymers "Nylon and Moisture Absorption". It's real and a known characteristic.
When I worked for a Maintenance Company in 1988 89, we ran green machines and soaked the 105 orange line in buckets with soap and water . It made the line last longer, didn't break as easy or tangle up as much
Yes in the real use world it makes the line last longer as its not brittle and just breaking off. One phone call doesn't amount to much of nothing but an opinion.
We were a Green Machine desler back in the day, good stuff ! SDK also manufactured early Shindaiwa stuff . No modern day trimmer can touch the old B45 and it's green counterpart.
To me I soak line for really old square spools that are sitting around. I buy in bulk so some boxes of spools take years to use up. The round line I buy from Husqvarna line doesn't seem to make a difference so I don't soak those. Seems the shape might matter. No idea, just what I have seen before.
Test it for yourself. Spool of some line and leave it hanging on a nail in your uninsulated shed, or even better, laying in the sun in your landscaping trailer for a year, and leave another off the same spool soaking in water for a year. Now test them both along a chain link fence, then tell me if you are gonna soak your line from now on or not.
Plastic and oxygen might deteriorate 🤷♀️ Once a week dunk it in water then. Got it 🚶🚪🦖 I’m gonna try this with zip ties….the dash of my pickup along with the door panels and interior trim I’m gonna need a swimming pool
The whole spool or just a working length? I tried this with a cut length and it was much better but as a domestic user the spool would dry out over time through limited use so I will continue to trim say 15' and leave it in a bucket of water for a couple of days before use and I think that will work fine
Interesting. I wonder what type of plastic it is. In 3D printing some types of filament become brittle and have printing problems as they absorb moisture from the air, and a heated filament dryer is used.
The manual for my husqvarna trimmer states that soaking the line overnight will make it last longer. It seems to make it softer and more flexible, so it's probably less likely to snap when it hits something solid.
You could probably wrap a new spool in cellophane if you're not going to use it for a while. When I'm painting a room in the house, instead of washing the brush out waiting for a coat to dry, I wrap the brush or roller in Saran wrap. Will keep it moist all day.
Nylon is hygroscopic. It looses moisture when the air is dryer or low humidity. When nylon is dry, it tends to fracture or break. I’ve found that soaking in water replenishes moisture and keeps line from breaking easily
This sounds bogus. It's plastic, it does not hold moisture, and it can't dry out. Submerging it in water would make it wet, but the water won't absorb.
OK, I happened upon this video and my question is relating to the trimmer head. I have about 5km on the big / bulk spools which i'm not gonna dunk till nearer the time i need to use them. But If soaking revitalises the line then can you take the strimmer head off (i have bump feeds on 2 of my Stihl machines) and dunk / soak the whole head. These are all plastic aside from the bump spring which i believe is stainless steel.
If polyamide nylon line is kept in a tightly sealed polyethylene container/bag and only opened during summer when humidity is the highest, there would be little loss of the original 5% moisture content. Then, line installed on a stored trimmer over the winter would be of the most concern. Are the line makers cheaping out on the packaging? btw, We've open package line that has been inside our non- AC house for 3 years and worked fine this past week.
I know that monofilament fishing line will absorb water the longer you use it while fishing and become heavier and won't cast as far until it is able to drive back out. That is the advantage of going ahead and switching to fluorocarbon fishing line. It is not porous and does not absorb water. Just thought I would throw that in.
I reel off ten meters to have in the truck (still away from light) and keep the rest in a cool dark place under the house. I have another reel sitting in an icecream bucket of water. But it’s sat like that for years. 😂
I'll have to try this I have a old roll of .095 about 3 years old now I noticed just this year not the string on the spool but my weed eater after it's installed and being used it's splitting on the ends it cost to much to just throw away and I'm not using the safety guard so it's not the cutter causing it to split
I have a big roll of nylon line. Had it for several years and it's not brittle. It sits on a shelf in my garage. Probably because it's not out in sunlight, it's not drying out and deteriorating at all.
What this about Honda pulling the 216/217 for sale? I hear it’s got something to do with the way the cam was built incorrectly as the didn’t let the cam plastic cool down after manufacturing before the next step so they are finding defective engines.😊

Is this fuckn satire? Used to do landscaping for a living and we never soaked line 😂 heck even now I’ve had the same roll for 4 years now that I’m no longer doing other properties and it’s just fine 😂
No, not satire. Completely true. If you watch the video, you will even see the logo that comes on every stihl spool, suggesting you to do so.
Nylon does lose some of its flexibility when it dries out, so this is no myth. It loses/absorbs water quite slowly though, and hydrated nylon does not feel wet or moist. If you kink the line and see it easily makes damage then it's likely too dry.
Unless your line is already dried up its enough to keep them in a sealed plastic bag away from direct sunlight. That's a fair bit more practical than having large containers of water sitting around. Especially since it can easily foul over time.
Good to know, thanks for sharing.

Awesome, welcome to the channel 🙂
Wonder if soaking in AmourAll would be better? Hmmm.
Most definitely not.
@@mainstreetmower Joking of course. Trimmer line is a copolymer. When it dries out and gets brittle, it's not losing water so soaking it in water is just getting it wet on the surface. Considering that the tip end of of the line is whizzing along at 600+ miles per hour and being literally melted away from friction with rocks, concrete and chain link fences, I doubt seriously that water does anything at all. If it makes you feel better, go ahead and soak your line.
@@jaydee5156 Check "The Materials Analyst, Part 85: Fixing brittle nylon product with water"...nylon holds 1.5-2% water by volume (finished product).
"Moisture acts as a plasticizer in nylon and therefore reduces strength and stiffness properties but increases elongation and toughness. In general, as moisture content rises, significant increases occur in impact strength and other energy absorbing characteristics of the material," from Amcopolymers "Nylon and Moisture Absorption". It's real and a known characteristic.
This is baloney.
Nylon doesn't absorb water, and what bakes out of the plastic is not water.
When I worked for a Maintenance Company in 1988 89, we ran green machines and soaked the 105 orange line in buckets with soap and water .
It made the line last longer, didn't break as easy or tangle up as much
Good to know. Thanks for sharing Mark 🙂
Yes in the real use world it makes the line last longer as its not brittle and just breaking off. One phone call doesn't amount to much of nothing but an opinion.
@@Robert-j9k5i Agreed. Just wanted to share that opinion. ☺
We were a Green Machine desler back in the day, good stuff ! SDK also manufactured early Shindaiwa stuff . No modern day trimmer can touch the old B45 and it's green counterpart.
Soap is a great idea. When it dried it would coat the line with fatty esters which would tend to seal in moisture.
Wry interesting. Thanks.
You are welcome Andrew 🙂
I soak mine in a bucket of my kids tears and the yard work does itself.. highly recommended.
Can't believe it would make a difference but I guess it does. Who knew-not me.
Right!
To me I soak line for really old square spools that are sitting around. I buy in bulk so some boxes of spools take years to use up.
The round line I buy from Husqvarna line doesn't seem to make a difference so I don't soak those.
Seems the shape might matter. No idea, just what I have seen before.
That's great insight. Thank you for sharing.
Test it for yourself. Spool of some line and leave it hanging on a nail in your uninsulated shed, or even better, laying in the sun in your landscaping trailer for a year, and leave another off the same spool soaking in water for a year. Now test them both along a chain link fence, then tell me if you are gonna soak your line from now on or not.
Let us know next year ☺
Interesting
Cool
🙂
I would have said this is bullshit but I learned something new.
I have some ten year old Stilh line without that soak symbol, so this is something recent. Soaking does soften the line though.
Good to know. Thanks for sharing
Plastic and oxygen might deteriorate 🤷♀️
Once a week dunk it in water then.
Got it
🚶🚪🦖
I’m gonna try this with zip ties….the dash of my pickup along with the door panels and interior trim
I’m gonna need a swimming pool
Why would you call sthil? They don't make the line.
They are the ones who sell it though.
It's just like with any plastic. I rejuvenated an old rc car that is almost 40 years old by soaking the plastic parts in water.
The whole spool or just a working length? I tried this with a cut length and it was much better but as a domestic user the spool would dry out over time through limited use so I will continue to trim say 15' and leave it in a bucket of water for a couple of days before use and I think that will work fine
I never knew...
Right! And It's right there... a logo on every stihl line.
Interesting. I wonder what type of plastic it is. In 3D printing some types of filament become brittle and have printing problems as they absorb moisture from the air, and a heated filament dryer is used.
....and next you will tell us to store our batteries in the fridge.
The manual for my husqvarna trimmer states that soaking the line overnight will make it last longer. It seems to make it softer and more flexible, so it's probably less likely to snap when it hits something solid.
I soak my fishing line but them big fish still break the line sometimes.
You could probably wrap a new spool in cellophane if you're not going to use it for a while. When I'm painting a room in the house, instead of washing the brush out waiting for a coat to dry, I wrap the brush or roller in Saran wrap. Will keep it moist all day.
Nylon is hygroscopic. It looses moisture when the air is dryer or low humidity. When nylon is dry, it tends to fracture or break. I’ve found that soaking in water replenishes moisture and keeps line from breaking easily
This sounds bogus. It's plastic, it does not hold moisture, and it can't dry out. Submerging it in water would make it wet, but the water won't absorb.
It was hard for us to believe too that's why we called the HQ directly!
It does. Look into drying 3d printer filament.
You need to use your own intuition, if Stihl told you, you can use spaghetti for trimmer line, would you believe it.
Ofcourse I don't!! Plastic doesn't get inside the plastic and doesn't do anything
Plastic trimmer line soaking up water ???? I've got a "Banana plantation" at the South Pole, that I would love to sell to you !!!
So. How come no one asks how often this process needs to be repeated?
There's no set period of time it depends on your use and how often your line gets brittle (with what i've understood)
OK, I happened upon this video and my question is relating to the trimmer head. I have about 5km on the big / bulk spools which i'm not gonna dunk till nearer the time i need to use them. But If soaking revitalises the line then can you take the strimmer head off (i have bump feeds on 2 of my Stihl machines) and dunk / soak the whole head. These are all plastic aside from the bump spring which i believe is stainless steel.
its that damn cheap just buy more
If polyamide nylon line is kept in a tightly sealed polyethylene container/bag and only opened during summer when humidity is the highest, there would be little loss of the original 5% moisture content. Then, line installed on a stored trimmer over the winter would be of the most concern. Are the line makers cheaping out on the packaging?
btw, We've open package line that has been inside our non- AC house for 3 years and worked fine this past week.
So by their admission it doesn’t extend life, why the hell would you do it. Makes zero sense.
It’s restores it to its original plasticity when it has become brittle
I would’ve never believed that. I might would have if someone told me to spray it with wd-40 or something like that.
Hi, Cool Stihl agent over phone! I really enjoyed him explaining the thing, also he felt to me like friend telling something to friend. COOL !
I know that monofilament fishing line will absorb water the longer you use it while fishing and become heavier and won't cast as far until it is able to drive back out.
That is the advantage of going ahead and switching to fluorocarbon fishing line. It is not porous and does not absorb water. Just thought I would throw that in.
I try to soak my line every night.
I reel off ten meters to have in the truck (still away from light) and keep the rest in a cool dark place under the house.
I have another reel sitting in an icecream bucket of water. But it’s sat like that for years. 😂
I'll have to try this I have a old roll of .095 about 3 years old now I noticed just this year not the string on the spool but my weed eater after it's installed and being used it's splitting on the ends it cost to much to just throw away and I'm not using the safety guard so it's not the cutter causing it to split
Why call when it's instructed on the package?
To confirm.
Doesn't work, tried it and no
My local STIHL mechanic told me the same thing.
Measure line thickness before soaking in water and then measure again afterwards. If there is no significant difference this will be your answer.
If it prevents it from cracking and breaking off as often then yes, it does extend the life of the trimmer line…🧐
I only soak my line in boiling water when I replace the line on the spool. It just makes the line more pliable, is all.
Thank you
Soak it in warm water
Water is not going to do anything for your string. It is an extruded plastic.
Don’t leave it in the sun and it’ll be fine for years
the Sthil manual recommends soaking
I have a big roll of nylon line. Had it for several years and it's not brittle. It sits on a shelf in my garage.
Probably because it's not out in sunlight, it's not drying out and deteriorating at all.
Good to know, thanks for sharing.
What this about Honda pulling the 216/217 for sale?
I hear it’s got something to do with the way the cam was built incorrectly as the didn’t let the cam plastic cool down after manufacturing before the next step so they are finding defective engines.😊
