I have a great ability to break most things. So when I read about
boiling pieces, to clean off compound before moving onto the next
compound, or soaking in stain remover liquids, etc, I had visions of
stones cracking, blanching, or some other awful thing and thought
that I would ask first! So, how do I clean a piece between polishing
compounds? Also, is it simply left over compound that I’m seeing in
bright sunlight on a polished piece, as almost a shadow? (darn hard
to remove - acts like a stain and vigorous rubbing with a polishing
cloth doesn’t make a fig of a difference).
Many, many thanks in advance!
