Ever look inside the gas tank of an old motorcycle and see nothing but rust? It's really common and there are products out there to either get rid of the rust or supposedly coat and seal the tank. Well, maybe, but, since a chemical reaction caused it, why not reverse the whole process and really get rid of it?
I was flipping through the pages of the latest Motorcyclist Retro and found an article showing the straightforward process of electrolysis using a battery charger, washing soda and a bit of wire. You combine the simple ingredients, fill the tank, insert the wire anode, turn on the current and let the fun begin. A couple of days later, no rust.
If you're the type of guy who likes to restore old bikes, next time you run into a rusty tank, give this a shot and see how it turns out. It works on smaller individual pieces, too. Pretty cool.
