FLITZ Non-toxic, eco-friendly cream formula. Safe for cleaning, polishing and protecting all metal (except gold plating, it can strip gold). Works on fiberglass, plastics, and other surfaces. Removes oxidation, tarnish, rust, and discoloration.
I made the mistake many years ago on a Western Field 20ga SXS. The reciever looked kind of dull and dirty so I used Flitz which I clean my knife blades with. In a Flitzflash it took the case colors clean off.

The first two lines come directly from Flitz advertising.

Have you tried Semi-Chrome?

Thank you for the input.
The frontier pad didn't work for removing the plating.
I think the flitz polish or simichrome may be the right avenue. I will try that next.

I would not use Flitz unless you want to remove/dull ALL finishes. Flitz works great on chromed type finishes.

Have you thought about taking it to a jeweler? They might know the exact treatment to use.

excellent suggestion jeff

I will pursue that the next time I am in town.
Thanks for all the suggestions.
