Thread: Remove oil from bone scales

Wrap the scales in tissue and put them on a warm radiator for a day or two. The heat will sweat the oil out of the scales and hopefully clear it up!

This might not get all of it (depends on how much is in there), but it will definately help a lot and wont risk any further staining or marks.

Give it a try first as its the least aggressive approach and then move onto chemicals and whatnot.

Hope that helps!
