MAINTENANCE.

General.
WARNING
Crazing (cracking) of lenses will cause re-
duced effectiveness of the light. Do not use
cleaning agents (which will cause crazing)
such as strong detergents, solvents, or petro-
leum products. If crazing of lenses does occur,
reliability of light for emergency signalling
purposes may be reduced until lenses are
replaced.
Ordinary cleaning of the plastic lenses can be
accomplished by using mild soap and a soft rag.
Should fine scratches or a haze appear on a lens, they
can ordinarily be removed with a non-abrasive, high
quality, one-step, automotive paste cleaner/wax and a
soft cloth.
