I was initially really excited to get my Dunes CC...then when they arrived they had a strong bad smell and the colors were a bit drab. I am planning to use your method this week to hopefully reduce the smell and brighten them up. I really like the Dunes design but they could be more vibrant IMO. Still great looking chips and I think the oiling will do the trick.
just make sure you do the washing with mild soap (like dawn) and water first. you don't need to scrub fiercely, but a toothbrush or the like to get to the corners helps. there's dust, and probably some kind of releasing agent, in those mold impressions. even after a good cleaning, you'll still see some of that color on the cloth or paper towel when you oil them.
