I say again, that we should have a link to dirty chip cleaning somewhere--preferably on http://www.ccgtcc.com

Having said that, my method (other than for paper inserts and I don't clean those chips] is to use a mild detergent and a soft tooth brush; then I wipe the chip dry on a paper towel; apply a light--very light coat of Vitamin E oil and then wipe that off with a paper towel.
