Hi, I also have not had much luck, with yellow ivories. However, I think my problem was, the hydrogen peroxide I used was 3%. I read somewhere, that it should be the 30%. I found a source, and it was $30, for a litre, I think. I just haven't got around to purchasing some, and trying it. I wonder if wood bleach and neutralizer would work? Regards, John M.
