The Power of Electrolysis | How To Transform Rusty Tools!

There are many ways to remove rust from metal, but this shocking method is my favourite! In this episode, I show you how you can transform your rust-ridden objects into shiny showpieces, using the power of electricity! SAFETY NOTICE: Use in a well-ventilated space or wear a mask, as the bubbles can be hazardous!

Good video showing the practicalities of doing this. However, although this is being referred to as electrolysis, it isn't using the electrolysis to transfer rust to the anode in the way anodising works. What is actually happening is that the water is being separated into oxygen at the anode and hydrogen at the cathode. The oxygen is highly reactive with the metal anode and rusts it. However, at the cathode the hydrogen doesn't react but effectively blows the rust off the surface, sand blasting at atomic level. The result is that the rust on the rusty item ends up in the water, which is why it goes brown. There is no transfer of the rust to the anode. In fact, there ends up being more rust as there is now the rust on the anode and the rust from the item in the water. The anodes don't even need to be sacrificial for this to work, you can use stainless steel and it will still work, although some stainless steel will still rust under these conditions. This also works as a paint stripper. I use this to remove the paint from metal items. They don't need to be iron, so long as they conduct. It's best to lightly scratch the paint surface if possible but it works fine with old Dinky cars, etc. and works out much cheaper than using paint stripper, plus it's less toxic or harmful, both to yourself and the environment. I also have an easy way of remembering which way to connect: +ve to "adding rust" -ve to "subtracting rust".

[@pennyan2057]

Hey Alien, I have an aluminum powder coated black fishing reel spool that's corroded from salt water, I've tried methelene chloride stripper with no results. I want to remove all the paint without damaging the spool so I can powder coat it again, think this method is worth a try????

[@lordchickenhawk]

@@pennyan2057 I'd be interested to try this too. One Mr McBeardy commented on this video that he used borax instead of washing soda. I'd be interested to see if dilute borax might be gentler on alloy in this application as it has a bit lower pH

[@lordchickenhawk]

Hmm... perhaps no, from what I can find the opposite might be true. At least, from some articles I have been reading it could be very dependent on temperature, current density and borate concentration. Too involved for a casual workshop like mine anyway.

[@marshalltjones]

There are two types of rust. The first step of the rusting process produces Magnetite (Fe304), which is tightly adherent to the iron and is black in color. If you leave it longer, you get red rust (Fe2O3), or hematite. Red rust takes up more space than the iron it replaces, so it flakes off. The electrolysis process causes the red rust to detach from the underlying metal because of the bubbling. The black rust that underlies it actually is reduced back to metallic iron by the current. The density of the resultant iron is maximized by using a low voltage 2-3 volts over a long period of time, but the 12V method also works pretty well.

[@anthonykrusel349]

To Marshall Jones: Thanks for the good info. I've got a microwave oven transformer I've rewrapped that produces 2.8VAC. Will AC voltage work for this and what amperage suggested as starting point? I adjust current with multiple halogen bulbs in parallel to MOT source. Thank you, Marshall Jones

[@TheOwlman]

@@anthonykrusel349 The process is polarity sensitive - watch around 5:00 carefully and you will see that you need DC (also, the anodes are sacrificial, so you never want your part to be the anode). I can certainly endorse what @Marshal Jones said, a lower voltage is a much better idea - I use a benchtop power supply set to around -4V- *Edit:* 6V and also limit the current to keep the rate of gas evolution down (one thing Dom failed to mention was the gas, you need to do this in a well ventilated space because it is going to produce free hydrogen and oxygen gas).

Brilliant video. Recently started blacksmithing and bought some old tools to get up and running and this looks like the ultimate way to restore them to their former condition. Thanks to all who have highlighted dangers from poor ventilation. I would add the importance of switching off power BEFORE disconnecting any components as even a small spark could ignite that oxy/hydrogen mix. The process is similar to charging a car battery and I have had to give first aid to someone who removed lead with power on and the spark blew up the battery. (almost blinded him) Careful !!!

Kudos to you, a very practical demonstration of the technique. Having checked my chemistry, the rust is being reduced to iron, but as the rust flakes are no longer well attached to the base metal, the rust becomes something like iron filings. That's the grey residue that's left behind. Another Repair Shop fan, and I deeply, deeply admire your signwriting skills. My hand was never steady enough.

Thank You so much for a good educational video. I have a lot rusty tools to practice with🙂 In Denmark some artists make sculptures in some kind of wax, and paint it with, I think cuprium sulphat.

In Denmark The artist Galschioett is doing it, for years and has maked large scales models that way. As example a model of The godess of liberty in more than six foot tall. They have a big tank ive been told. Can You please show in a small scale how to do, and what needed to perform this proces?

Ah the wonder of science. Great tutorial Dom as usual.

[@paulkramer4176]

I've used electrolysis many times. Dom's vid is good. I've often done a pile of things. Don't even have to connect wires directly to all the parts, as long as they are touching each other, it works. (better of course to connect wires). Also, as to only a few hours, depends on how rusty the items are. I've occasionally needed to leave the product in for a week. No big deal. Does a stunning job. NO elbow grease required. Leaves the finished product sort of "black". Why? Cause the hard to remove red rust, (ferrous oxide) is replaced with ferric oxide, (black rust). Black Ferric oxide is fairly easily washed off, leaving a clean surface. sometimes you have a BIG item. Easy to build a wooden frame, lined with plywood, then line that with polyethylene sheeting. You can put in a large free standing machine that way. As Dom said, don't use a fancy charge controller. Some of those don't recognize what you are trying to do, and don't "see" a battery, so won't work. You can trick those by putting a battery inline too, so that it thinks there is a battery that needs charging though.

I have been using electrolysis for a number of years. It is a permanent part of the tool restoration business here at Old Sneelock's Workshop. I use to be in charge of repairs in an aluminum anodizing shop. I replaced the expensive stainless steel tanks with plastic lined steel. When I retired and started restoring tools I used large wooden boxes lined with plastic sheeting for electrolysis. You can put very large pieces in a wooden crate and it is inexpensive to make any size you need.

I would warn against using just any kind of steel for the sacrificial anode(s). If you use a Stainless or relatively high Chromium content steel, it will make your leftover water very poisonous. Not something you should then pour down the drain! So, only use mild steel and similar for your anodes.

I've used this method s lot & it never gets old! It's an amazing technique. What looks like hopelessly rusty metal comes out looking better than you could ever get using old fashioned wire brushing & hours of work. As you could see on the file, it reveals lettering that could easily be lost using abrasive methods. One thing, the older the better when it comes to battery chargers. You don't want any fancy modern components in there. Just a basic, old fashioned charger. I used old, sheet steel computer case covers for my sacrificial terminal. Laying it over the bottom of the tub & then suspended the items I was cleaning above it. That was all the items were close to the metal as it covered the whole bottom of my plastic container. If the computer case cover is painted or powder coated on one side then but that side to the bottom.

Over the years, I have slowly built up my basic woodworking skills and collection of tools... now you have me thinking of looking at metal. Thanks... I think (could be an expensive diversion, but a bit at a time and I may be able to pull this off)

Mohamma time! If I hadn't seen that hammer, I'd wondered for ages what this mysterious Mohamma was.

I remember using this same process 70 years ago. Isn't it strange how reinvention takes place at regular intervals!

[@mrmyorky5634]

Yep, we used the same process but in my case it was 60 years ago. We also used many other different processes using chemicals that would be strictly illegal today. We used to heat rock Sulfur in an open pan over an open flame until it liquified and use it as a glue/gap filler to fix steel shafts into wooden rollers. We also had an open molten cyanide hardening bath to give a hard surface to steel components and for many years we also had an open Tricoethylene degreasing tank the operator of which was always seriously affected by the fumes by lunchtime. In our ignorance we assumed that he was just a secret drinker combined with being a bit crackers anyway.

That's a nice hammer by Cornelius Whitehouse of Cannock 😊👍

1980, ex-MOD, judging by the crowsfoot

[@garypautard1069]

I remember Whitehouse hammers they manufactured excellent drywall / roofers hammers during the 80s.

There are many ways to skin a cat in regards to getting rust off of an item. A hammer wasn't the best example in my opinion for two reasons. The first reason is that hammer was usable as a hammer regardless of rust, the only issue would be if you were worried about the surface marks it could leave and you wanted to make sure the face didn't have pitting. The second reason is that the item is easy to use other methods on, such as the wire wheel. Where this process shines is in complex shapes where a wire wheel cant get into, or areas that are seized with rust and something like an acid bath would not penetrate deep enough without first damaging other areas of the item being cleaned. What I see is a bunch of comments completely discounting the process because there is a different method available. And while I do agree if you were going to use a wire wheel on it... I would have started there and maybe bypassed the whole process, but the video is about the method used and how to do it, not necessarily stating its the best option for what you used it on. Someone else in the comments stated they used it to clean our gas tanks from the inside out, that is brilliant, and its a good example of the perfect use for this technique because trying that with a wire wheel would be ill advised. Long windedness aside, great video!

A real craftsman at work many thanks.

Very nice job. I like having my tools looking well kept.
