Personally I think that’s part of the problem. Not all chips need to be cleaned and not all chips need to be cleaned so aggressively that they’re left “chalky.” And I put chalky in quotes because I usually use that work to describe factory mint Paulsons (which I also would prefer not to clean and would never consider oiling.) I’m not exactly sure why aggressively cleaned chips come out dried out and gritty. I’m not sure if it’s all chemical residue or if the ultrasonic cleaners have something to do with it. But many of the chips I’ve cleaned have done great with just warm water, dawn, and a scrub brush, and didn’t come out all desiccated and gritty.
If you haven’t figured out my little bias on this one, I think that in general, PCFers do more cleaning and oiling of their chips than is necessary, merely to interact with them. Just play poker with them!
