easy Dino, he's just being him, I think everyone on the thread is aware that our tech tip section has a page about using vinegar as a rust remover, and molasses as well [and maybe even Coke, which contains phosphoric acid] .... I take his comments as saying there's better acids to use than vinegar, no harm, no foul, just chatter, he prefers Phosphoric acid, I prefer electrolysis, the same comments show up in every discussion of vinegar for derusting
