Gold Cup Lens Cleaner & Anti-fog has been used in industrial applications for years. We finally found a supply in bulk and knew we had to use it for paintball goggles. Gold Cup Lens Cleaner has been used in foundries, steel mills, and cement plants in the hottest of summers and the DEAD COLD of the winters and it has handled it all. The best thing that can be said about the cleaner is that it simply works and WORKS WELL! The same quality can be assured in this lens cleaner that you have come to expect in all of Gold Cup Paintball products.
