When to Check

LENS:
A small amount of dust or dirt on the lens has minimal effect on image
quality—to avoid the risk of scratching the lens, clean the lens only if absolutely
required. See below.
LAMP REFLECTOR:
Inspect the mirror surface (reflector) for cleanliness only during a
lamp replacement, when the lamp is out. If necessary, clean as described below—
make sure to wear protective clothing while inspecting or cleaning. Note that color
on the reflector surface may vary—this is normal.
Supplies
For cleaning off dust and/or grease, you will need:
•
Soft camel-hair brush
•
Dust-free blower—filtered dry nitrogen blown through an anti-static nozzle.
•
Dust-free lens tissue such as Melles Griot Kodak tissues (18LAB020),
Optowipes (18LAB022) or Kim Wipes or equivalent
•
Lens cleaning solution such as Melles Griot Optics Cleaning Fluid 18LAB011
or equivalent. For lens only.
•
Methanol. For reflector only.
•
Cotton swabs with wooden stems only
•
Lens cleaning cloth/microfibre such as Melles Griot 18LAB024 or equivalent.

Cleaning the Lens

IF DUSTY
:
1. Brush most of the dust off with a camel-hair brush and/or blow dust away with
compressed air.
2. Fold a microfibre cloth smooth and gently wipe remaining dust particles off
the lens. Make sure to wipe evenly with the smooth portion of the cloth that
has no folds or creases. Do not apply pressure with your fingers—use the
tension in the folded cloth itself to collect the dust.
3. If significant dust is still bound to the surface, dampen a clean microfibre cloth
with lens cleaning solution (damp, not dripping). Wipe gently until clean.
IF FINGERPRINTS, SMUDGES, OIL
Brush most of the dust off with a camel-hair brush and/or blow dust away
1.
with compressed air.
2. Roll a lens tissue around a swab and soak in lens cleaning solution. Tissue
should be damp but not dripping.
3. Gently wipe the surface using a figure-8 motion. Repeat until blemish is
removed.

Cleaning the Reflector

IF DUSTY:
1. Brush most of the dust off with a camel-hair brush and/or blow dust away with
compressed air.
2. If some dust remains, just leave as is—air circulating at the lamp is unfiltered,
so some dust is inevitable. Avoid unnecessary cleaning.
