Lye water? Answered

Can you use lye water (potassium hydroxide solution) to bleach bones?

Discussions

If you're near a dairy farm or any place that uses a "Trench Silo" I have a friend that buries cow & deer skulls in the pile in the Winter for a couple months & it leaves them clean enough that they can be electroplated with chrome for folks that like a modern touch. Hope it helps! I think some people cook them for extended periods of time.

Use bleach, or sunlight.
Potassium hydroxide might clean them up nicely, but it's not going to whiten them any more than that.

If I remember correctly it turns bones into soft rubbery things.

I doubt it - It's normally used to make soap and is very caustic.
