A bit of a necro-post, but this is important.

So, first things first: Don't mess with higher concentrations of Hydrogen Peroxide unless you are a trained and well-equipped chemist.

  We're talking "Steel-reinforced gauntlets" here. Dead serious. The stuff is as volitile as nitroglycerin.

At 3% you have mostly DI water and for good reason. Hydrogen Peroxide is extremely, violently unstable, and is just as likely to oxidize anything it can get it's grimey hands on than what you actually intend to react it with.

Anything above 30% is very dangerous. Above 60% is suicidal in ill-equipped scenarios. 100% is a hypothetical, and is in essence a potential component of rocket fuel.

So, whew boy, yes it will work.

  You may lose a hand, but it will work.
