Oakite BCR (buffing compound remover) is the one most industrial
trade shops use… its the purple stuff you buy repackaged for twice
the price. A 5 gal drum is about $60 and goes a LONG way. Oakite
1 800 231 5040 I t cleans quick and is easy on the hands. It is
formulated just for bufing compounds.
For cleaning behind stones before working use Pure Magic.
Fargotsteins and I think Swest have it. It cleans the stuff outta
the back of stones that two hours in a top sonic cannnot clean.
Put a small amount (1 oz) in a small sealed jar and suspend in your
cleaner. I dont know whats ion it but it works!
To clean rouge from behind diamonds, if the piece is true 14k and
the solders are too, use 14kt nitric testing solution. a few
drops around just the stones and a ten or twenty seconds , followed
by a rinse in the sink then a cleaner bath will get out even the
most stubborn rouge… REMEMBER THIS IS A DANGEROUS ACID! dont get
it on your hands… it will cause them to turn brown. dont get it
on other metals or stones, it may damage them, and DONT EVER EVER
use around CYANIDE or follow cyanide down the drain without LOTS of
water in between.
