I deal in mostly used Casino chips from Washington State. I came across this cleaning solution when I had some really dirty Paulson Chips I was trying to sell. Diamond Casino Products only sells this cleaning solution, by the gallon, to casinos such as Bellagio, Foxwoods and MGM. I persuaded him to let me sell it in 16 oz. bottles. Each bottle will clean about 250 chips. Let me tell you, this stuff really works!! Just soak them for a few minutes and wipe them off with a soft towel and WOW! Very Limited supply, but I will get more.
