Great to see someone presenting low cost solutions rather than hawking sponsor products. ~Add a little salt and / or cheep(battery charger) DYI DC electrolysis setup to your vinegar soak tank to speed up cleaning time greatly.
You changed my life! I was previously killing myself with 2 x 72 felt belts to remove the mill scale from my steel knife blade blanks. Thanks so much!!!
Thanks! Cleaning mill scale off with a grinder is the worst part of every project. The mess, time, and cost of new flap discs or bristle brushes takes its toll too. Can't wait to try this out.
I use white vinegar to remove mill scale off small items I have to weld in the same manner you do👍, but wanted to add or recommend the use of Evaporust immediately after rinsing if you want to prevent flash rust and help protect the part until you get a chance to paint or oil it, depending on its use. I just immediately submerge the parts in evaporust and then dab them dry them with shop towels and usually coat with 3 in 1 oil. Then when I'm ready I just clean with acetone.👍
Use straight swimming pool acid (muriatic acid). It works in 20 minutes or less. Rinse part in clear water, buff surface to get a shine. Also, this is useful to strip zinc galvanizing off of steel prior to welding (rinse & buff the cleaned steel).
Typically the concentration primarily affects the rate of reaction. Concentrated acetic acid is a referred to "weak" acid, but it can burn you. I know from experience.
I had some extremely rusty 1890 coach screws...a 24 hr bath in white vinegar {Sarsons}and they cleansed up beautifully {antique toy}..was so surprised, and coated them with linseed oil afterwards. I hate using toxic chems too. :)
good idea of you're poor, but if you're soo concerned about your health, i mean a respirator goes a long way just saying, but in my shop we use sandblasters for removing millscale and it works perfectly. vinegar actually causes corrosion and millscale in the long run. my old leatherman can vouch for this.
Just a hunch, but a person should probably be advised to wear rubber gloves when handling these parts in the solution (even if it's just mild steel in vinegar).
Love the idea. Unfortunately, most of the mild steel parts I'm working with are at least 48" long and having a 50" long container with sevral gallons of vinegar in it would be in the way in my limited shop space.
Have you ever seen the channel MichaelCthulhu? He creates an elevated area with bricks and scrap wood around his work pieces and lays a tarp over and creates a shallow bowl to do his vinegar baths.
Soak paper towels in vinegar and coat the area you want to clean. Either wrap in plastic or top up with vinegar to stop drying out. Give it 24/48 hrs. Stinks the place out but works pretty well.
Paul Hahn you could use muriatic acid. It burns you if it gets in you. You need to use full ppe there is a “less toxic” version of it but it does not work as well. All of it make a big mess. Do lots of research on how to protect yourself.
Ya really shouldn't let any acid soak in your shop. Even vinegar (acetic acid). Yes it's mild, but smell that? That is some getting in your air in a semi closed space. Even covered those fumes will rust stuff in an accelerated manner. Guys have used Muratic acid (HC!) in their shop which works really fast by the way, buts hazardous. Poor guy found just about everything metal was rusting one week later. Ion your not in a hurry, white vinegar works well on mill scale. But cover tightly and try to do it outside if you can. Also heat accelerates the process with vinegar.
What do you mean you don't know whether it is stronger or not ?? !! The 'Hines' (or at least the one you showed here) clearly shows 9% on the jar. I am sure that other generic brands will also show their strength. eg if it shows only 6% than you can assume that Hines is obviously 50% stronger and if it is only a dollar dearer than it is definitely better value and will last longer.
@@MonkeyFabGarage Not sure what you mean by 'obsess much' ? However I have always assumed that people put up videos to help others by giving them the facts they need to know to do the job. When using chemicals to do something it is obvious that another potential user needs to know how strong to make the chemicals. So it is imperative that things like this are stated to remove uncertainty. You stated early on that you didn't know how strong Hines was in relation to other vinegars. I was pointing out that at least you know how strong Hines is. I have just checked the 4 bottles of vinegar I have and NONE of them state how much acid is in them so that annoys me a lot. If they only have say 2% than I might assume that I need to leave things 4.5 times longer to get the same affect as you do using Hines. This is stuff I need to know. Not obsessing at all. Just need to know to set my expectations.
@@MonkeyFabGarage Okay if you say for example that you leave stuff overnight with 9% vinegar (this 9% will be referring to the acetic acid content which is the active ingredient of vinegar) then if my vinegar happens to be 2% then I might expect to have to leave stuff in there for 4.5 days instead of 1 day. And that since there is a lot less active ingredient in 2% vinegar that I maybe would have to expect to top it up every day or so. Hence knowing exactly how much active ingredient there is is quite important. Since my vinegar does not tell me how much active ingredient there is in the bottle I am going to have to contact the manf and ask them. I suspect that they should be doing that anyway since the labeling is incorrect by law. May be they had too many labels printed and are using them up ?

Dr. Douglas Hepler lol. Not my invention at all. But it works.
Well, thanks anyway. You presented it well.
@@MonkeyFabGarage Well, thanks anyway! It is a God-send.

Thanks for the video, I tried it with some parts I made, worked really well, great improvement over the mess with flap discs.
Excellent! Thanks for sharing 👍🙏
What's that green disc you use?
Thank you for this! I have a bunch of steel to prep soon. I’m curious about implementing this. 🙂

Much obliged!
All household vinegar is 5%. Brand doesn't really matter; it's the price. Horticultural vinegar is 20%, obviously much stronger, maybe too strong.

Never again!!! Thank you so much for this lol... Grinding scale off hot rolled mild steel is the worst!!
DanOfTheNorth yeah especially that super thick stuff on hot rolled. It’s horrible
White vinegar is typically 5% acedic acid and 95% water. It will also dissolve your concrete slowly.
I had some extremely rusty 1890 coach screws...a 24 hr bath in white vinegar {Sarsons}and they cleansed up beautifully {antique toy}..was so surprised, and coated them with linseed oil afterwards.
I hate using toxic chems too. :)
Good job on the vid!
And after you finish using the vinegar for this, you can use it in a salad.
Extra iron! You don't have to take vitamins anymore!
MMMX38 maybe a cure fore anemia lol.
I use mine for pickled eggs.
Awesome! I honestly didn't think it would work on scale, thanks for the share man! 😁
Pickling vinegar is 6%. I use same
Muriatic acid is Hydrochloric acid.

the active part of vinegar is acetic acid.
It's a chemical.
It's an acid.
Also sucks wearing out flap wheels at 2 or 3 bucks a piece taking mill scale off when you can do a thousand pieces in a gallon of vinegar.
Very informative video. Thanks.
Dude. Thank you!!

Maybe a tube in upright position? Good for long blades, swords and stuff.. that would be minimum space consuming.
Is there a way to use vinegar for sheets of metal? What do you suggest for removing mill scale off large pieces of hot rolled sheet steel?
Paul Hahn you could use muriatic acid. It burns you if it gets in you. You need to use full ppe there is a “less toxic” version of it but it does not work as well. All of it make a big mess. Do lots of research on how to protect yourself.
How would do plate or 2” sq tube?
Get 20 to 30 percent vinegar on amazon, not this stuf. And vinegar is acid
good stuff thanks for sharing this one, it will be very useful

I wish that worked with stainless steel. I tried it tonight with Muriatic Acid, and it doesn't work. What a bummer.
This old Tony have an episode where he mentions pickling. Something to clean stainless with. I think the episode is about bench bender.
Vinegar is acetic acid and is also a chemical. Like everything else in the universe.
Thanks man

how do you do this with large parts ? pressure washer w/ vinegar?
Part Out
larger container. It has to soak to work. On a closes container, the fumes from the vinegar are effective as well
Reusable PVC gloves are $7 at Home Depot
Add some salt bro I been doing that for 30 years.
completely safe, but tastes like crap, I mean honestly who uses this stuff in food? This is CLEARLY what it was initially made for.
RAGE AGAINST THE WORLD we’ll have you ever tried fried pickles?
