Removing chrome oxide polish from rutilated quartz


#1

Anyone with a suggestion to remove chrome oxide polish from a faceted
rutilated quartz where the polish has gone down the tube under the
surface? Ultra sonic and steaming, soaking in acetone has not helped.

If you can’t remove it maybe you can “bleach” it to colorless, or at
least the same color as the quartz. Have you tried any solvents in a
vacuum debubblizer? I’d try ZEP floor stripper. It has a pH of about
12. I use it instead of ammonia and soap in my ultrasonic. (I immersed
a variety of stones in some of it undiluted for 6 months to test it
and it damaged nothing, not even amber or pearls.)

Have you tried soaking it in cooking oil then probing the openings
gently with a safety pin?

Can only suggest leaving it soaking in water with a drop of a
wetting agent (detergent or ammonia) for several days and then
ultrasonic bath in water with ammonia again. Ammonia acts as an
anti-flocculant and so helps separate all the fine particles thus
making it more likely they will shift.
