SO you basically dissolve the oxy in hot water and then you illuminate it with "black light" overnight. Rinse and repeat three times.

Good. Everything's good that works. I found all the "original" and "improved" retr0bright recipes doing as much harm as good, next to requiring definitely non-negligible effort. I eventually found one that works well but takes lots of time. Yours seem as best compromise. Shall have to try it.
