If you’ve enjoyed the fun pleasure of testing your reflexes against a frenetic pinball machine, then you’ve probably stared right at Mylar -- a polyester film that provides a resilient layer of protection to a variety of surfaces. Mylar was invented in the early 1950s and is used in a growing number of applications, including clock and computer displays, X-ray film, test strips and even university ID cards. It’s better to be safe than sorry when cleaning Mylar film so that it does not peel or crack. So get back to basics to get your Mylar film back to its original shiny state.
Place the Mylar film on a flat surface.
Pour a few drops of mild dish soap into a spray bottle. Fill the bottle with lukewarm water and shake it well.
Spray the Mylar film with the soapy water.
Dampen a sponge with lukewarm water and clean the Mylar film in a downward motion, as if you were using a squeegee.
Spray the film with glass cleaner.
Wipe the Mylar film with paper towels, using the same downward motion to prevent streaks.
If the Mylar film does not lay flat, ask an assistant to help you rather than securing the edges with tape. Even masking and painter’s tape can leave some adhesive behind on the Mylar.
