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’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.
Cleaning Procedure for Large Areas - Automated
1. Clean the surface using a high-pressure water cleaner
(max. 100bar or 1,450psi) and/or a steam cleaner.
We suggest that a test be made on a small area, prior
to cleaning the entire sheet.
2. Use of additives to the water and/or steam should be
avoided.
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.
• For all mentioned chemicals consult the
manufacturer’s material safety datasheet (MSDS) for
proper safety precautions.
Additional Important Considerations for
Multiwall, Corrugated and Sign sheet:
• Cleaners and solvents generally recommended for
use on polycarbonate are not necessarily compatible
with the UV-protected surfaces of Lexan multiwall,
corrugated and sign polycarbonate materials.
• Do not use alcohols on the UV-protected surfaces of
Lexan sheet.
• Never clean the Dripgard surface of Lexan multiwall
and corrugated sheets.
