Hi folks, have a vibratory polisher with walnut media, it has a liquid additive to allow it to polish, but it appears to be pretty useless, i ran it for 5 hrs and it made no difference to the parts i placed into the unit.

My goal is to use it to clean small musical instrument parts, that is for example a nickle silver key that is heavily tarnished, if i take it and put it up against a mop with some rouge it comes up like shiny silver.

So my question, should i add some rouge that i use on my mops into the walnut media to help with the polishing or something else.

Steve
