Thanks for the mention. I find that after the tiles have been whitened, they don't stay white for too long. However, there is another version of retrobrite that uses an additional reagent (a small amount of the "active oxygen" laundry booster TAED as a catalyst) in addition to hydrogen peroxide. I have not yet tried that.
