Got a piece of plexiglass I'm going to paint some screen paint on and made the unfortunate mistake of taking the plastic covering on plexiglass off, before hand, so as to inspect the plexi and now I'm having a bit of hard time cleaning all the random cloth fibers, from using cloth to wipe the plexiglass off, and getting rid of water stains from rinsing in water. Need some advice from you guys on how to clean the plexi off so it's crystal clear again.
