Here is what is used by antique telephone and old radio enthusiasts.

This Novus #2 Cleans and polishes and removes scratches from Bakelite, plastics, fiberglass and painted surfaces.

We used it to clean up painted telephones and bakelite. It does wonders.

This will also remove haziness and discoloration.

Can also be used on windshields and motorcycles. We are buying this item monthly so you receive a fresh product.  We are selling  the larger 8OZ  bottle 

Beware of people selling old outdated stock.
