While the guys are correct, a cleaning and oiling is a pain in the back, it definitely fixes 99% of the discoloration. At least on the 2,300 my wife and I had to clean and oil. We spent our entire time binge watching 7 seasons of Yellowstone, 1883 and 2 seasons of 1923 oiling these pricks, which gives you an idea on how much of a time suck it was, but I can honestly say everyone at my home games literally thought I’d bought new chips the difference was so drastic.
