Thanks WH, this stuff just accumulates in my brain.

If the maker of something says it's OK with H2O2, coolio. However, you can do your own compatibility test in a teacup. A little water, some of the material you want to test and some H2O2. If the mix foams or bubbles when you add H2O2, chances are there's organic materials in the material you're testing and H2O2 is breaking them down.
