Cleaning
ETC offers the following recommendations when cleaning and inspecting lenses and
reflectors:
Do not
use glass or window type cleaners on lenses (glass or polymer) or reflectors.
Do not
use abrasive materials such as steel wool.
Replace lenses if they contain visible damage (cracks or deep scratches) that may impair
their effectiveness.
Cleaning 19°, 26°, 36°, and 50° glass lenses
1.
Remove the beam focus knob at the bottom of the barrel. Remove the lens tube
from the barrel.
Note:
It is not necessary to remove the lens for cleaning. If you do remove the
19°, 26°, or 50° lens, make sure the identifying paint dot is not removed
during cleaning. See “Lens Locations” below.
2.
Dampen a clean lint-free cloth with vinegar or household ammonia. You may also
use water, but it will leave spots that can be removed by gently polishing the lens
with a clean and dry cloth.
3.
Starting from the center, gently wipe the lens.
4.
Slide the lens tube back into the barrel with the color frame retaining clip on top.
Replace the beam focus knob.
Cleaning 5° and 10° polymer lenses
To quickly clean the lenses, remove dust with a blast of oil-free air. If this is not sufficient,
follow the instructions below. You will need a Phillips screwdriver.
Caution!
Handle polymer lenses by their edges only. Never rub anything dry on a
polymer lens.
1.
Remove the beam focus knob. Gently pull the lens tube out of the barrel.
2.
Use a Phillips screwdriver to remove the brackets that hold the lens in place.
Remove the lens from the tube.
3.
Dip the lens in a clean alcohol/water mixture (10% alcohol).
4.
Use a moistened nylon bristle brush to wash the lens' smooth side in a linear
(non-circular) motion.
5.
Use the same brush to lightly wash the lens' ridged side by following its ridges.
6.
Dip the lens in a clean alcohol/water mixture (10% alcohol).
7.
Dry the smooth and ridged surfaces with an air gun. Make sure that the air flow
moves liquid away from you.
8. Inspect the lens for dirt. Repeat steps 3-7 if necessary.
9. Set the lens back in the lens tube with the ridged side facing the front of the
tube. Replace the lens brackets.
10.Slide the lens tube back into the barrel with gel frame retainer on top. Replace
beam focus knob.
