Hoping someone may be able to help here. I have a few sheets of invisiglass that I wasnt currently using on my Pins. I stored them in my back room in basement which isnt part thats finished. After a few months I took them out and cleaned them with the proper product(sprayway ammonia free) but there are what seems to be water droplets that I can not get out. They appear as little white water droplets. I cant tell which side they are on, they almost appear to be in the middle of the glass. I tried taking pics but it doesnt really come out on the camera. Anyone have this happen before and was able to resolve it?
