Is there any truth to that statement?
I use stainless steel shot in a vibratory tumbler to work harden and
polish some of my fabricated 14/20 Kt. gold filled parts with good
Very little, if any of the gold is removed in the process and the
finish is actually harder as the shot burnishes the surface. The
parts I make are small and narrow. The type of jewelry you intend to
clean/polish may not fare as well if there are broad surfaces or set
I have not used abrasive cleaners on gold filled but of course that
would remove some of the gold surface.
