Hi, I got a cleaning fluid very cheap. It says 30% hydrogen peroxide and peracetic acid at pH 1. This is very cheap, and solves two problems at once. If it works, then others can use this too, it is sold in 40kg cans. But peracetic acid is a strong oxidizer afaik, can it still be used?

what concentration is the peracetic acid in the solution? if it is like 1% then it is just being used as a stabalizer to slow the decomposition of the H2O2. I am going to assume for now that that is its' purpose. you will still need to add a mineral acid to the mix (you want to be informed about AP production right?) like H2SO4 or HCl. I am sure you can find it, so there is no need to "kill two birds with one stone" by buying your hydrogen peroxide with a trace amount of acid in it.

Isn't it simply a mix of vinegar and H2O2?
I guess so!
CH3-CO-O-H + H-O-O-H < === > CH3-CO-O-O-H + H-O-H
Thus
CH3-CO2H + H2O2 < === > CH3-CO3H + H2O

It only says peracetic acid pH 1 on the can. I read somewhere that TCAP only needs hydrogen peroxide and acetone, then the reaction speeds up when it gets under pH 2. The hydrogen peroxide 30% sign is at least very clear, the soup is spicey.
If that
CH3-COOH + HOOH < === > CH3-COOOH + HOH
is right (I guess so too) then there is maybe some CH3-COOH left in there. Can I still use this, by adding a mineral acid? Is there a chance this might blow prematurely because of this? I can not see why, but...

No there is no reason since it is diluted and remains in solution!So after cristallisation, the cristalls just need a good usual wash with distillated water!
