Clean spandex screen
So I just finished up my new 110" milliskin spandex screen. I absolutely love the size and picture but somewhere along the way I get some kind of little black smudge on the screen.
Is there anything I can do to spot clean the spot? It's right in the middle of the screen so I'll be screwed if I have to rip use whole thing apart and redo it.
Any advice would be extremely welcome!
