Hi guys. I was wondering what the best way to clean my goggles are. Last week, my goggles were splashed with methanol-toulene (1:1), and unfortunately, I didn't clean my goggles properly, and now, there are dried-up, translucent spots all over my goggles, which is an annoyance. What's the best way to get rid of these spots? Would acetone do the trick? Thanks again.
