Here is the screen with the Elmer's Washable School Glue on the screen. I never had a problem getting the glue out of the screen before but during the Maine Event I had to cut out the screen and replace it. Not a big deal but it was odd. I think it was because I left it on over a week. This screened cleaned up pretty easily.
Here is the screen and glue. I think the blue glue might be easier to remove.
