Is this the return of the greatest YT channel of all time, some rusty tool needing restoration? The Myford resto is one of my all time favourites of anything on YT.

Geoff... this is carrying your relationship with rust; initially Myford rust, then Landrover rust, to a level of intimacy that might be seen as unhealthy! 🥴 From my viewpoint as someone who found fourth-form chemistry totally baffling, you are either a very clever-dicky, or you have been smoking unmentionables! 😵‍💫 Brilliant video, thanks. BTW: I have got my Myford Super 7 running. My father bought it 72 years ago (when I was five years old), and handed it on to me forty five years back. It has been stored for sixteen years in a damp environment, until I got it back in a very sad, very brown state, about a year ago. After a complete tear-down, paint/rust removal, and rebuild, and new motor, it is a joy to behold. Your video series became my invaluable companion throughout the process... thank you so much! 👍 Plenty more to do on accessories... the fun goes on. 😃

Very well done and explained! Thank you

Glad you’re back!

As a watchmaker I can confirm that vinegar does dissolve small steel parts. We use it to dissolve seized steel parts in brass if we can’t get them out any other way. It only discolours the brass but the steel will be gone in a few days. Pretty handy if you break off a drill bit smaller than 1mm in a brass part but it does take a while. Can’t use it to remove rust on such small parts though, or you might loose the whole thing!

I LOVE these kind of explanations! Simple, informative! It often bugs me when instructions just say "use this type of glue", or, "use this type of grease". Yes, but WHY that particular kind of stuff and not some of the nine other kinds of whatever I have. Sure, videos would become veeeeery long... but... I WANT TO KNOW! 😂 Great job with the video and graphics! 👍

Great lil explainer, thanks.

I was not expecting a chemistry lesson when I switched on KZread this morning. That was nicely done, I am starting to suspect that when away from KZread, you are something of an educator.

Hi jeff I like vinegar on my fish and chips. I am glad I use my fingers to eat them and not a knife and fork. I'd be in trouble if I destroyed our cutlery. Love your videos. Your helping me through a 1955 107 resto. Cheers Phil.

Just so you can sleep at night, chip shop vinegar isn't actually vinegar... Ethanoic acid (I think) + water + colour & flavourings mixed to replicate vinegar

This is actually a very good explainer. I was always worried that if i left my parts in the vinegar too long that it would eat away at the base metal. After watching this i don't think it does if i understand correctly. Thank you!

I'm pretty sure it does, I left some cast iron lathe gears in vinegar for a few days and the got very "etched", as I understood this if there was no water in the vinegar it wouldn't attack the iron, but it seems the water is necessary for the reaction to dissolve the rust.

@GeoffreyCroker

It does. Vinegar dissolves iron in steel just as readily as rust. But the iron in steel is so dense compared to rust, that you'll probably never notice. At least not on large objects.

Surprisingly well animated for an old rust bucket channel. Seriously, it's a very nice video. Not sure why you suddenly decided to make a chemistry video though. But I'll watch if you make more.

I used vinegar soaked paper towels to remove the rust from the fenders on the car I'm restoring. I let the paper towels sit overnight, covered with plastic. Worked like a charm!

Great explanation. Now i need to know just how electrolysis rust removal works

Thanks for explaining, I used this method on my tools and always wondered how it worked. I had to watch it twice for the electrons to free up, the brain is a bit rusty.

Always enjoyed your videos, your talent is very evident. Never gave any thought to what your occupation was, but now I'm curious as to what your 'day job' is? Thanks for taking your time to make and share the videos. .

Good old first year college chemistry. Thanks for the memories!

U make great videoa please upload more

Get your geek on! Thanks, that was fun.

It seems that owning a Land Rover makes you become an expert in rust. Just kidding Geoffrey, thanks for the explainer. I think I need watch the video two more times to understand it fully. Good infotainment!

Thanks for the lesson! I enjoyed it, and it’s nice to know the science behind it. Probably could do some maths to determine how much vinegar you would need/want to suspend a part in given its size and weight based on that.

That explains a lot.

This is wonderful, doing what many state schoold failed. Just two questions. How much will you need for an old rover? And does it change the smell/taste. I guess its just going to smell like driving back from the chippy. Although with vinigar rather than non-brewed condiment

Fantastic, and a great departure from the regular LR fare - yet still decisively Croker. A nit, though: neutral atomic oxygen has 8 electrons; I suspect what you were trying to convey at ~1:50 was oxygen’s oxidation state, which is indeed -2. Oxidation state is a subtle thing and difficult to explain, depending as it does on _where_ the electrons are in their particular configuration - even in a neutral atom. Excellent video - more; please!

Isn't this chemistry.....

No bloody wonder I failed chemistry....

Very interesting and an extremely lucid explanation, thanks Geoffrey. One issue still puzzles me though, as we all know, the presence of high humidity or moisture in the atmosphere in our workshops accelerates the formation of rust on all forms metal. I can see this in operation in my workshop during the rainy season every year. Rust is prevalent and accelerated in high humidity areas. So how does this fit into the equation ? if Rust is Fe2O3 where is the H in all this ? We know that Water is H2O so why no H in the Fe2O3 ?

I wish you would have been my high school science teacher 😅. On a side note, I was looking forward to your music montage with some heavy metal undertones. Maybe next time 🎉

Mate. My KZread feed says this was put up one day ago. It reminds me of the videos you did a long time ago and how I subscribed to your channel. Is this something new because the Landrover got certified, or is KZread buggerizing around? Great explanation btw.

Great explanation of the science behind the process. I'll retain "vinegar dissolves rust" from your video. It kinda reminds me of algebra proofs. I used to tell the teacher to skip the proof and I'll just accept the formula on faith. I mean why would my math teacher lie? 😊

I prefer citric acid. It removes rust without producing black oxide which requires rigorous scrubbing to remove.

I found your channel when you started the Land Rover restoration. Never ever I would have thought I would end up watching a chemistry lesson from you. Also, I didn't understand anything apart from acid + rust = no rust. Nevertheless, it was fun to watch anyway

Im back in school. Better expressed than back then. 😊

I got lost at some point so I have a question. Does the removal of the rust leave a vacancy at that part of the iron. Did the rust removal carry away some of the iron? I think I see that it did. Well, it wasn't iron anymore anyway. It was rust. Good little journey of a video. A little boring but good. Shakes up the brain cells. Thank you. I liked the nickel electroplating you did way back. Absolute magic. That was terrific. Seems it's quite expensive to purchase the kit, but so's everything these days. Thanks, Sleep Joe.

@iteerrex8166

I looked it up. It had been a while since I did chemistry. It’s a covalent bond, due to the first orbit having room for one more electron. The two H atoms share their electrons. Cool 👍

does it need to be neutralized after you’ve removed all the rust? will it do damage or compromise the integrity of the metal?

No. Just rinse it off with water. You can 'neutralise' any acid with anything alkaline, like soapy water or baking soda if you want to, but it's not necessary.

It absolutely reacts with iron.

Your model at 6:30 of ferric acetate is not consistent with the equation. It looks like a compound of 2 iron atoms with all 6 acetates but it is clear that it should be 2 compounds of 1 iron and 3 acetates. At least I think that's how you balanced the equation.
