Cleaning the Domes
Periodically cleaning the domes using proper procedures and compatible cleaners
will prolong their service life. Unlike the reflectors, the domes do not have to be
removed from the light bar for cleaning.
CRAZING/CLEANING SOLUTIONS: The use of cleaning solutions, such as
strong detergents, solvents, and petroleum products, can cause crazing
(cracking) of the light bar lens and reflectors. To clean the reflectors, use a
soft, damp cloth. To clean the lens, use a soft cloth and a solution of water
and a mild detergent.
CRAZING/CHEMICALS: Crazed, cracked or faded lenses or reflectors
reduce the light output and the effectiveness of the lighting system. A lens
or reflectors showing this type of aging must be replaced. Failure to follow
this warning may result in bodily injury or death.
To clean the domes:
1.
Rinse the domes with lukewarm water to loosen dirt and debris.
2.
Use a mild soap, lukewarm water, and a soft cloth to gently clean the plastic
surfaces. To avoid damaging the reflectors, do not use heavy pressure or
caustic, abrasive, or petroleum-based cleaners.
3.
Rinse and dry the plastic surfaces with a soft cloth to prevent water spotting.
To remove fine scratches and haze, use a specialty plastic cleaner/polish and a soft
cloth. You can also use a high quality automotive paste cleaner/wax that is non-
abrasive.
Cleaning the Reflectors
Use a damp cloth to gently clean the plastic surfaces. To avoid damaging the
reflectors, do not use heavy pressure or caustic, abrasive, or petroleum-based
cleaners.
