'Clairoxide', that's a Hairdressers-product right ?
It may contain, for key-caps and hairdressers, undesirable chemical additives AFAIK .
The recommendation is to use min 10-14% hydrogen-peroxide, however it may be problematic
to find it these days as it can apparently be used by Al-Cracker to produce exploding shoes and underwear ..
If you do find it : WEAR GOGGLES AND CHEMICAL GLOVES !!
I **** you not, this stuff eats your skin and/or eyes !!
