Oooh..
Don't say peroxide.
I had a bad experience at work about seven years ago with peroxide (10%) and H2SO4.
To this day, I'm the only one who knows about it.
Shhhh........
Well I wasn't going to mention the acids but since you brought it up:) Sulfuric acid is one you can use and a strong concentration of hydrogen peroxide. This is what they were going to be using in some kind of slurry solution in a false bottom of sports drink bottles. The slurry would be died to match the color of the drinks.
