Lexan* Sheet Cleaning Recommendations
These cleaning recommendations apply to all Lexan polycarbonate sheet products, including, but not limited to, Lexan
solid sheet and signs, Lexan coated Margard* sheet and Lexan multiwall sheet.
Periodic cleaning using correct procedures can help to prolong service life. For cleaning, it is recommended that the
following instructions be adhered to::
Cleaning Procedure for Small Areas - Manual
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
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..
Other Important Instructions for All Lexan Sheets:
- Never use abrasive or highly alkaline cleaner on Lexan polycarbonate materials.
- Never use aromatic or halogenated solvents like toluene, benzene, gasoline, acetone or carbon tetrachloride
on Lexan polycarbonate materials.
- Use of incompatible cleaning materials with Lexan sheet can cause structural and/or surface damage.
- Contact with harsh solvents such as methyl ethyl ketone (MEK) or hydrochloric acid can result in surface
degradation and possible crazing of Lexan sheet.
- Never scrub with brushes, steel wool or other abrasive materials.
- Never use squeegees, razorblades or other sharp instruments to remove deposits or spots.
- Do not clean Lexan polycarbonate in direct sunlight or at high temperatures as this can lead to staining.
