[pianotech] Bleaching Ivories

[Tom Servinsky]

The sunlight doesn't loosen the ivory. Rather it's the repeated liquid peroxide treatments that eventually weakens the glue adhesion.
The lamps do take more time, but less peroxide is needed, thus glue issues are lowered.

  You'll do much better with sunlight because it works much faster. I find the lamps require to much time and that's what loosens the ivory.

    List,
    I have used peroxide gel and uv lamp on heads with good results. My question is, will the heads and tails loosen or curl using gel and sunshine .
    I don't want to get into reattaching ivories. Just want to improve color.
