The folks behind "RetroBright" are all good people, but they use concentrations of H202 that are just beyond reason. ... you only need cheap, drug store 3% peroxide to do the job, in conjunction with some OxiClean. Indeed, using a tad more OxiClean seems to work better and safer and cheaper than highly concentrated H202 mixes.

The irony is that the OxiClean actually increases the percentage of H202 in the mix as it breaks down, so the more you add the higher the concentration of H202. So, more is obviously better, but clearly there is a tipping point of negative returns.

By the way, where did the corn starch come from? Was that your own substitute for whatever they use on RetroBright? I don't recall as the idea of the gel never interested me much due to the poor and streaky results they were getting with it (of course some of that could be attributed to the high H202 content).

Also, where did you finally get your pure H202 without stabilizers and antiseptics (and which was not obscenely expensive)? LOL That seemed to be the single major obstacle you faced. Do they now think you are making bombs in Japan? LOL
