I'm not sure what else to call it, so I'll stick with resin fog. I recently got an early DW-6100 & the inside of the crystal has "resin fog" from what I can only guess is from age & off-gassing of the watch. I was able to get at some of the crystal with a Q-Tip but there are places I just cant quite reach between the plastic insert & the crystal. I really don't want to try alcohol for fear of lifting any of the original paint. Has any one been able to find a way to clean up this residue?
