How to Remove Rust With A Battery Charger

Cleaning tools by electrolysis……….In this film I am getting rid of rust on some fine machine tools by putting them into a home made electrolytic bath powered by a battery charger.
This is a very simple set up to do at home, but do take care as both electricity and chemicals can be dangerous – so only do this if you are familiar with this sort of thing, and the potential hazards, including the washing soda!
My set up is very simple, I use a car battery charger and a sacrificial electrode on the positive clip – any old iron rod will do; then on the negative clip I put the piece of rusty metal that I want to clean – this is then put in a plastic bucket filled with water and washing soda. After about 20 minutes the tool should come out fairly clean and a bit of wire brushing will bring it up very well indeed.
In this film I clean up a milling hold down set that I picked up in my local scrap yard and it comes out really well.
