CARE OF REFLECTORS
Reflectors should be cleaned periodically. A mild soap and
water solution or fine cleaning powder is best although more dras-
tic means may be required if reflectors are badly soiled by chemi-
cal or other deposits. The reflector is aluminum. DO NOT use
alkali cleaners since alkalies will dull reflector. Mild non-alkaline
cleaners, such as used for scouring kitchen sinks, amy be used.
Reflectors are replaceable and may be purchased from Chromalox.
