Cleaning
Use the provided wipes or other lint-free, non-abrasive optical grade
wipes. If you choose dry wipes, use analytical grade isopropanol or
ethanol to moisturize the wipes before application. Do not use any
other cleaning agents or wipes, as they can damage the optical sur
-
faces.
Wear powder-free laboratory gloves during cleaning to keep grease/
salt from your skin away from the verification filters.

Prior to mechanical cleaning, rinse the verification filters with de
-
ionized water or blow off loose dust/particles. Shake off excess
water.
2
If particles or stains remain on the filter after step 1, carefully wipe
the optical surfaces. Allow residues of the cleaning agent to
evaporate.

Check the optical surfaces. Repeat the cleaning procedure if
there is any residual dirt.
