This is definitely one of the best RUclips videos I've ever seen. It is not just edited at a good pace, one you can follow and understand, no annoying background music, just enough technical information to show up that the speaker knows what he says, and of course good realistic and credible demonstrations. I think this is a model to follow. Thanks a lot, Geoffrey Crocker, you earned a follower in Peru.
Yes , I agree entirely. His video was as good as an episode of NOVA on rust removal of all things . SUPERB .
Yes seriously 🙌🏻
ржавчина это Fe(OH)3 или Fe(OH)2, а не Fe2O3 а так всё по делу
Finally, someone who adequately explains the chemistry behind the various methods. Thank you!
Probably the best blend of chemistry and practical view of the rust removal issue on RUclips. Ill go for 12v 5A on a 25Lt plastic container, with good ventilation...
"This involves science." Donald Trump please stop watching the video now! lol :)
@Schwalbe262 yet still true no matter how old it gets :-)
Thorough and intelligently demonstrated. The chemical reactions and the use of a pH scale for reference are big pluses. Great video!
YES
Very much agree, from a Chemistry Graduate
I've watched and read a lot of information of all the methods you presented here. I'd say your presentation is the most complete and comprehensive for the home gamer perspective. Big thumbs up for taking the time and sharing your findings with us.
Thanks Shain
Not only does this channel fulfill my land rover restoration needs, it taught me how to restore and take care of my tools
Thanks mate
Thanks so very much for this. Im resoring a 100+ year old bike and this video has been exactly what I have been looking for. Much appreciated.
Finally a comprehensive video from someone know knows what he's talking about. Great help, thanks.
love how you show the elemental reactions. I'll take your word it is done accurately.
That was the most coherent demonstration and explanation of this topic that I've seen - and pitched at just the right level for the hobbyist. This and the one on plating that I watched just before. You've given me the confidence to start trying this stuff. Well done - you are a born teacher.
I love the way you visually represent the chemical aspect of this information.
This is a one hundred percent better explanation than most. This is a true explanation of how you can go about things. I certainly appreciate it.
I admire the choice of music from ALL of your videos Mr. Croker
Most informative video on RUclips I have watch in a long time. Precise & clearly presented. Excellent graphics. Thank you, thank you, thank you!
Very informative and you have a nice presentation. I can use this in my science class. Thank you for this video clip.
Great overview. Wish I had started here in my Rust remodel journey. One comment on electrolysis : I used electrolysis to clean up an old frying pan. After about a day the top of the water sodium carbonate solution was covered with a reddish foam. I made a spark with the electrical connection 12 v. And the hydrogen oxygen bubbles in the foam EXPLODED. There was no damage to anything but the incredible kaboom from close up gave me tinnitus that endures years and will be with me till I die. If you doubt me and plan to test this for yourself wear hearing protection.
Love it! You brought it to the next level man! So interesting to watch, all the chemistry and stuff. Very useful video, well done!!!
I know it's almost 4 years later but... awesome! Great video Geoffrey. Thanks for putting this together.
Rust in peace at the end, nice touch!!!
Great video, truly quality content
Your very methodical and clearly communicated approach makes me suspect that you are very talented teacher. You have certainly taught me a few things. Many thanks.
Great video! So much value! I would have never thought vinegar was so weak, I've used it in the past with good result but as you said I left stuff in there for a long time :') Thanks man!
Thanks Black Beard. I think vinegar works ok if you give the part a scrub every so often to help it along, but I wanted to keep the comparison with the other acids so I didn't touch it.
This is a complete overview of rust removal methods, and very well done at that. Bravo!
With regard to electrolysis, the use of a carbon anode instead of a steel anode will eliminate rust scum from floating on top of the solution in the electrolysis container. See the Shopdog Sam videos on this subject on his RUclips channel. Once he started using carbon anodes, he never had to change his solution because of floating scum. These carbon rods are available from welding supply houses.
For quicker action with vinegar, use a 30% or greater concentration, but wear gloves and work outdoors - the fumes are very strong.
I have been searching for days to understand these technical details and I found them all in your video. Thats very generous and good of you, thanks from OZ.
excellent video, edition graphics and sound, a piece of work and time taken. Really nice job.
As always, a cracking good video. Many thanks for presenting an evidence based review of the various options we builders have, and delivering it all with just a gleeful touch of humour.
Finally, someone who knows what he’s talking about. Thank you, that was really informative. I watched the video several times.
Awesome video, pertinent, clearly enounciated, to the point, with nice behind the scene science explanations and great points on safety and real world affects to metal. Subbed.
I've been looking for this video for the last year. I've been getting my 1987 Suzuki samurai running and slowly restoring in the garage. Its got some surface rust on most parts and I have been looking for the right avenue to remove the rust. THANK YOU SO MUCH FOR MAKING THIS VIDEO! Greetings from Los Angeles
Geoffrey that was the best and most understandable test and description of how each of these methods work, all I need now is a massive plastic tank and quite a few phone chargers so I can immerse my Mini shell into!! Thank you for taking the time to make this excellent video.....
Completely brilliant video. Straight to the point and super informative without digressing in details.
You did it! This is *the* best video I've seen on rust removal. Thank you!
Geoffrey, A big thank for posting this video it's excellent! I've got a car restoration project I'm doing and the electrolysis method you show works perfect! Thank you very much for taking the time to educate others.
Great info. So glad you mentioned the fact, that it doesn't have to be washing soda and that salt will work just as well, seeing as, you're only increasing the conductivity in the water.
Excellent overview Geoffrey, one of the best on this subject, thanks for this !
Great vid... beautiful work with great explanations.
Keep them coming Geoffrey
Fantastic, finally some actual information (and very useful information at that) instead of high-res, time-lapse beauty shots. Thank You!
Now, please please please do a video explaining the best way to treat a deck. That information is of little use to me, but it would make my day to hear you talk for 20 minutes about all the best ways you've learned to take care of your deck (preferably with copious "accidental" innuendos, delivered totally dead-pan)!
I am glad you entered in your last little part with the grinder. Always the best option.
The best video on rust removal, period.
LOVE that outro, wasn't expecting it at all. Subbed and liked. Good vid, thanks.
I've found dipping parts in a 20% Phosphoric acid solution and leaving for up to 24 hours dependent on severity of rusting to be the most effective method for 100% removal. As you mentioned it will corrode and etch the steel, but after a full 24 hours I've found the effect to be truly negligible and the etched surface left is also excellent for painting.
Yeah, phosphoric acid is the way to go. Infrared heater (conductive heat) will speed up the process. The colder it is, the slower the reaction. Does not eat steel much at all.
This is exactly what I've been looking for! So helpful, thank you!!!
Top video! I wish you were my science teacher in school - I remember these diagrams but never did any electrolysis!
It was so clearly explained that I thought I'd give electrolysis a go. First rusty bolt is fizzing away as I type. Really enjoyed watching your vids during lockdown in the UK. Thanks for helping me pass the time and learn something new.
the goat video about rust . nobody could tell me otherwise
Hi Geoffrey, you are the first person I have heard pronounce water correctly. Thanks ;-)
That's called a scientific approach: covering all the why's & wherefores. Excellent!
Bruddah you nailed um. Straight to the point, just the info we needed. Mahalo for making this.
Perfect survey! I'm going to set up my own electrolysis station. Thanks for the info Geoffrey!
How, can someone dislike such an interesting and well done video? Like your Job! Thanks Geoffrey - Tom from germany
Geoffrey, absolutely brilliant video, both content and presentation! You've covered all bases and given me an easy way to set up a simple electrolysis system. I use that particular tannic acid product all the time for outdoor touch-ups as the coating acts as a primer (or final coat if I'm lazy). Love the dry Kiwi humour!
Excellent description of all the alternatives. Thanks for this vid!
excellent video. best I've seen on the subject. I'll be going the citric acid route as I don't want anything aggressive to clean up my 40 year old Snap-On old feeler gauges
Worth bookmarking. Practical, helpful, well done.
Great video explaining the process. I used vinegar to remove rust from hand tools and remove rust from tools that I could easily had to trash them. It did not come out 100%. Definitely they came out how lot better and cheaper and very useable
I appreciate your explanation of the usefulness of each process. I've used them all except Evapo-Rust but I didn't know the ideal scenarios for their uses. Practicality means a lot and I learned that even Phosphoric Acid has its place -- for a pre-plating wash. This is brilliant. I am undertaking a motorcycle restoration and the fuel tank is slightly rusty, inside. I will probably start with Citric Acid based on this video and up my rust removal game. Thank you.
Super useful video, such a pleasure to have all this info in one place & great that you had the fortitude to see it through. I have used most of the methods & agree with you that the wire brush is the best, so immediate & so none disrupting of the work process. If I am over painting I tend to use wire brush then rust convertor, accelerated with hair dryer & then prime, hair dry, top coat. Somehow the wait times for the other methods cause too much of a loss of momentum. Thank you for sharing!
Excellent descriptions. All of your plating videos are excellent. Thanks
This is an excellent tutorial on rust removal. Thanks for making and sharing this video.
The lemon juice trick saved one of my stained glass windows that I'd had to leave sitting for several months! The flux wasn't getting the copper foil clean and every thing online said vinegar but that wasn't making any kind of difference. I tried lemon juice and was finally able to clean up the copper so I could solder it. Thank you!
Hmmm. Copper is an entirely different metal, right? The topic here is iron oxide, the rust formed with materials with a ferric content.
@@boxsterman77 That doesn't mean that copper doesn't form a patina that makes it impossible to solder. Copper foil is too fragile to scrub away the patina without destroying the foil. Does it really matter that it wasn't exactly what the topic of the video was covering if the information helped?
@@JanecShannon On the contrary, this made the video even more educational. I'll keep this in the back of my head for later.
wow you made a very good research on all the item you propose here... good work!!!!
beautiful video, well spoken and thought out. best video i've found on this topic
Really good tutorial - Thanks Geoffrey!
Thank you Geoffrey for your excellent videos and restorations, keep it up!
Greetings from Austria
Cheers Viktor
Thank you for your effort in explaining the array of solutions quite deeply.
Great video! I really appreciate your explanations and efforts.
Great stuff. Been using some of these methods for years but the explanation is just amazing. Like a boss for sure.
Jeez that was ace. You sure know how to put a video together Geoffrey.
Informative video. Enjoyed. Saw what you did there with the outro tune! Couldn't help but blow some air through my nostrils.
Very good explanation, explains the chemical reactions concisely and the results.
Excellent demonstration. One of the better ones I've see if not the best.
Spot on mate,you would make a good TV narrator as you make it sound so easy..thanks.
I very much appreciate this, I am looking to do some work on tools at home, and this will help me with a direction.
This is great... would love to hear more about safe and responsible disposal of the electrolytes / used chemicals. Excellent stuff thanks.
Bravo! A lot of great value in this tutorial. You wouldn't believe how many people do these and don't explain what they are using. The pace was easy enough to understand the information being conveyed. I own a cleaning company and use science and innovation to perform our duties. These videos like this are very good in explaining the "WHY". Awesome job keep them coming and I already hit the subscribe button.
Question: Would this process remove carbon and or heavy grease build up? Was thinking of using it on the metal grates on a stove top to remove all of the buildup which sits on most stove top burners.
Highly entertaining, informative. Well thought out. Well done.
Vinegar. There are a lot of guys out there who swear by vinegar. I didn’t mean to imply that vinegar is useless. If you’ve got time or help things along with a bit of scrubbing, it works fine. The point of this video was to show how the methods stack up - not whether or not they would ultimately be successful. Every method in this video works.
fair enough, it does work, but with more time, days or a week in my experience, but that may suit sometimes, and its handy for small stuff thats not gonna fly in electrolysis
Hey, you mentioned Citric produces C0? Does that mean it's not safe to use in my bedroom for cleaning rusty stuff?
Vinegar truly not useless. I had serious doubts, but while I was waiting on my oxalic acid to come in the mail, I soaked some rusty sockets in vinegar for 2 days, taking them out and only lightly brushing them with a wire brush a couple of times (seriously, putting forth almost zero effort in doing so.) Only 2/10 had any rust left whatsoever, and on those, the remaining rust was tiny and difficult to spot.
Using vinegar to clean out a rusty 20 gallon air compressor tank and it definitely works. Just not real cost effective when you need 20 gallons of it, so gonna get some oxalic acid powder as it seems the cheapest way to make that much solution.
Heat the vinegar beforehand and gaze at it dissolving the rust!
Thank you for the video, it helped a lot. I used HOT citric acid yesterday and it worked great.
I loved your video as I have used mostly white vinegar with salt and have had acceptable results but I really loved the ending where you threw down the real tool for rust removal of large items as I also love my angle grinder and to me it's the most versatile tool in my shop.
Amazingly competent/complete. Thks
Awesome video, best explanation on rust removal I have ever seen! Thanks!
Very helpful and informative. Thanks!
Nice work. Both clarity and conciseness.(SP?)
THANX
Thanks Geoffrey, nice effort all around and will serve me well as a primer on the subject as corrosion is part of life on boats and Im always working on mine. Slip in abit on passivation and this would be the hand out on all the boat bulletin boards! Cheers and many thanks for your work! CmCod
Love your work Geoff, I have only used vinegar in the past but i will try one of the other methods next time to see
👍 Thank you again (I've watched this in the past)
I am so glad I watched again ... your presentation & clarity is excellent ! I love the chemical explanations, they are so clear.
Much appreciated 🙃
Ted from Downunder across the ditch 😉
Deservedly well received video. Thank you for sharing your knowledge so succinctly.
Ha Ha....Loved the ending music from 'Rust In Peace'. Nice breakdown of the effectiveness of these products. Apparently I have what I need under the sink.
Awesome information, so well explained, if only all teaching was done like this. - Had to subscribe..!
Thank you man . great video. Helped me save lots of time of search and work
All acid require and an amine inhibitor to prevent damage to the base steel. Molasses has organic inhibitors along with oxalic acid. Also treating with lime water or sodium carbonate will stop the acids and leave the surface as light alkaline,. Excellent video - nicely done.
Great tutorial. Learnt a lot.😉👍🏼
this is gold information, you just help us save time, thank's mate, greeting from Bali
Excellent tutorial. Really well explained. My preferred methods are Hydrochorlic and Evaporust. I heat my Evaporust in a little boiler and it works brilliantly. As you say its not cheap but you can use it over simply by filtering . It does leave a black film though when it ages and you have to scrub it off and protect against flash rust if youre not painting straight away . Tool steel with high carbon will also stain black.
i found a great source of income for myself thanks to this video, restoration and resale of metal tools.
Excellent comparison video. I have some rusted brake discs to clean up, so I'll probably go with phos.acid at 40%, which worked well on rusty scaffold fittings. It's good to see you used a proper electrolysis pencil, too. They cost more than regular flat pencils, but they last a long time.
I fear electrolysis is a bit more complicated, but it still is one of the best videos on the rust removal chemistry.
You really did a great work by explaining every method in detail. Thanks man
Very well-explained! Thank you.
A very good simple informative video, Thanks
