Instead of creating another thread I will post my related question on this one.
What is the proper method of cleaning Da-Lite's high power screen material?
Manufacturer says that it is not recommendable to try to clean the screen. Has anyone tried the method they are recommending?
My screen has a lot of mildew/mold stains on it. Where I live the weather is quite humid, and that might be the reason. This didn't happen with my previous high power material, but well. I ruined the previous one while cleaning it. I just want to make sure that doesn't happen again.
