I know that phosphoric acid gives off a very acidic and toxic gas. I wanted to say hydrochloric and muriatic acid do the same. These acids etches ss and will also eat nylon fittings. Thanks shane for keeping me straight.

I was sitting here looking at the boxes of muriatic(hydrochloric) and phosphoric acid and got them all screwed up. Sorry about that. Both are nasty stuff to use them as catalyst would be hazardous to say the least. Don't know anything about the polymaleic acid.
