This should, not be taken as a do you clean, or do you not clean your chips. The following link will take you to The results I got from cleaning some pretty ugly chips. http://www.chiptalk.net/forum/poker-chip-care/28498-chips-headed-cleaners.html I found myself with large amount of very low value chips, very dirty chips , and decided to clean them. The results were very positive. The product I used is all natural. Some chips were left for 10 days soaking. I did damage to 2 chips. BOTH were cheap personal chips with stickers that came loose. Saw no damage to any quality chips.
