Try bathroom mould killer instead, oxyclean apparently destroys glitter, tinsel and things like the shiney symbols on the G1 princesses. It works great, but will eat shiney thing. Mould killer should still be used with caution, and make sure you don't get any on your clothes, it will bleach them, but its a really good thing to have instead of oxyclean at times too (and most of us have some for the bathroom anyhow)
