Rust removal by Electrolysis

[tommyhnavix]

Here is a little food for thought for restoration people. This is a relatively simple way to remove rust! It is really easier than it initially sounds.

These links will lead you through the process. It works awesome!! Basics are a battery charger, water, washing soda, plastic tank. Check it out. Makes rusty metal look like new in the white!! Part, tools and more!

I've done this using a battery charger and a old mower blade for a rust attractor, and used a highly concentrated Tr-sodium phosphate solution, it does work well. I have also used OSPHO, sold at Ace hardware and like it just as well because it actually leaves behind a sacrificial clear coat. You can wipe it on, brush it on, or spray it from a spray bottle (extreme caution needed on all applications to protect eyes, skin, and oxygen). If the rust is particularly heavy it produces a white effervescence that will need to be sanded/brushed off and another application of OSPHO over the area. On Magnesium I think a simple green solution or a strong TSP soaking will work well to etch for paint.

Very cool. I have a bow bar I may try this on.

I've got a 36" Mall two-man bar in my tank right now. The process works well.
If I'm doing a rusty chain, I use 50/50 vinegar bath as you don't have to worry about uniform rust removal due to electrical continuity through every link of the chain.

Took out the Mall bar and wiped it off. Don't have a before of it but it was pretty red with rust.
