I need information on is it safe to mix hydrochloric acid 35% and 3% hydrogen peroxide? I work with this strength of muradic acid all the time, for cleaning masonry work, but not at the full 35%.
Anyways have a vertrifed aluminum oxide sharpening stone that's full of embedded metal swarf that i am trying to dissolve the particles. I poured straight 35% in a plastic container with lid outside, with gloves and all safety precautions and its been in there for 2 days and some of the steel particles are dissolved but not good enough. So would adding 3% peroxide make this acid stronger or weaker? I read it makes peracetic acid, but i don't know much about it.
