I have a few odd projects, mostly cycles, that I need to go in and break up all the old surface rust. Does anyone know of any products or DIY methods (Someone mentioned vinegar?) to clean the rust out without cutting the tank open? I have this old Puch Maxi moped I’m thinking about restoring for shits and giggles. ---

Just a warning, since it wasn’t posted on the electrolysis site. Do this outside. During the process you will be giving off pure oxygen and pure hydrogen. Hydrogen will explode and oxygen will greatly promote a fire’s burn. ---

Depending how that turns out, I’ll try some of the products. ---

i would rather hear what the bb’s and the paint shaker sounds like. so your saying to leave gas in the tank? while shakeing? sounds a little dangerous. ---

Electrolysis is the best and easiest. There is no special shit you need, just a battery charger. I would seal it with POR-15 afterwards. Proven product. ---
