No I didn't clean these , but I have done some in the past. I used to bury some underground that came out all right. The bleaching is the way to go. I have a muskrat , mink and a beaver (not the wife ) laying around somewhere.
As a life long Mets fan , I decided to dig up my old baseball cards and autographs I collected as a kid. I'm missing the World Champion New York Mets team baseball card that my friend stole from me in 1970. Maybe I'll buy one on Ebay and send him the bill. Lol
