1.Gently wash sheet with a solution of mild soap and lukewarm water, using a soft, grid-free cloth or sponge to
loosen any dirt or grime.
2.Fresh paint splashes, grease and smeared glazing compounds can be removed easily before drying by
rubbing lightly with a soft cloth using petroleum ether (BP65), hexane or heptane. Afterwards, wash the
sheet using mild soap and lukewarm water.
3.Scratches and minor abrasions can be minimized by using a mild automobile polish. We suggest that a test
be made on a small area of Lexan sheet with the polish selected and that the polish manufacturer’s
instructions be followed, prior to using the polish on the entire sheet.
4.Finally, thoroughly rinse with clean water to remove any cleaner residue and dry the surface with a soft cloth
to prevent water spotting..
