Recently, I've noticed that I've got a blotch on my DaLite High-Power screen. To be perfectly honest, it looks like I've squashed a bug on it! (Its an electric screen, perhaps something was sitting on it when it rolled up :-) )
The result is that there is a dry, hardened spot on the screen. The spot itself is basically transparent, but it eliminates the gain of the screen under that spot. The result is that from the optimum seating position, the spot looks black.
What can I use to try to clean this off? If I try to scrape it off, am I going to scrape off the screen coating? What kinds of cleaners will not harm this material?
When I emailed Da-Lite they suggested I use 'warm water and soap'. (ie. a fluff, 'we-dont-know' answer).
