Quoting from the manufacturers web site:
CP-100 Pinball Cleaner and polish, "the blue stuff" as it is known within the gaming industry has been the original product from Gemini and is still a best seller world wide. No other product has been able to reduce the cleaning and replenishing power of CP-100 with its one-step cleaning and polish there is no residue. CP-100 first produced almost 30 years ago is the best product on the market. Pinball machines have changed over the years, CP-100 contains no water or harsh chemicals and we guarantee CP-100 to be safe on all surfaces. Containing silicone, CP-100 will revitalize and maintain rubber bumpers for longer life cycles and keeping them from cracking. CP-100 also works great on removing sticky residue left from stickers.
Note this has silicons and is not recommended for playfields if you are going to Clearcoat it - unless you carefully clean the playfeild with rubbing alcohol or similar to remove all the silicon residue.
Note - there are shipping problems with this product - it can only go GROUND. Remember that when ordering! We shall contact you prior to shipping if you accidentaly chose Air shipment.
On the other hand this stuff works great on mylared and Diamondcoat playfields and is recommended for 1980s and later games as a result.
