Rust removal

The Electrolytic Rust Removal FAQ
A technique for returning surface rust to iron. It uses the effect of an small low voltage electric current and a suitable electrolyte (solution).

I'll post the link to the web page at the end of this post. I tried this method last weekend and let the tank work for 2 days. WHen I emptied the solution from the tank the rust came out with it.
I was amazed at how easily this method removed the rust from the inside of my Allis' tank. It's incredibly inexpensive, all I had to purchase was a few pieces of rebar and some Arm & Hammer Washing soda that I found at my local grocery store in the laundry detergent section.

There are also methods to remove paint and grease from parts with this washing soda that I am going to try this weekend. Here's a link to the method.

Mix the solution and fill the container. Clean a section of the rusted part and connect the NEGATIVE wire from the battery carger to it. Immerse it in the solution with the rusted portion facing upwards. Suspend the iron rod in the solution making sure that it doesn't touch the rusted part. Connect the POSITIVE terminal to the iron rod, plug in the battery charger and set it to 2 Amps (or the lowest charging setting). For heavily rusted parts I let them work for 1 day then remove them to see howmuch if any rust is left.
