Default Re: Rust removal from steel component on the cheap.

Jenolite, active ingredient phosphoric acid, diluted to 10% with water, is brilliant for cleaning the pot-metal castings used for the shells of WW2-era W-connectors. They only take a few minutes and need watching carefully to avoid them dissolving!
