Sage,

Although it isn't one of your run-of-the-mill household products, try sodium perborate tetrahydrate. It (or one of the variants) is one of the ingredients in Oxy-clean. It is a stable, solid source of active oxygen prepared by reaction of sodium borate with hydrogen peroxide. When you dissolve it in water it releases back hydrogen peroxide; hence, it is a solid form of hydrogen peroxide. The monohydrate version yields about 32% hydrogen peroxide; tetrahydrate, about 15%. So all you do is mix up a saturated solution and you have fresh, high value hydrogen peroxide. Monohydrate goes into solution faster. My notes on this show that the commercial detergents contain only about 15% of sodium perborate by weight.

You can buy a 6lb. pail for $12.00 at

A supplier on eBay also sells a 1lb.jar of lab grade for $9.00
