Acetic Acid can be wonderful stuff, when used properly. Vinegar is nothing more than a very week solution of acetic acid. So, think of the acetic acid as being variable-strength vinegar depending on the dilution. Real good ventilation is a must. So is wearing rubber gloves. While at school, we used it (diluted, of course) to clean out the last residues of dead glue from the notches in the inner rim of a M&H BB. It's also incredible for cleaning out soap scum from tiled surfaces .... The stuff corrodes certain metals like nothing else -- chrome plating in particular. Do not use it around balance pins or front pins. Keep it away from your faucets while you're at it. As for photographic matters, it is used as stop bath, in that it instantly neutralizes the developer. The next solution, fixer, is also acidic and its job is to remove the unexposed silver crystals from the film or paper. This stuff loses its effectiveness if it also had to neutralize the developer, hence the use of stop bath. ZR!
