5.2.

Cleaning of optical surfaces

Take care not to scratch the lenses and optical coating while cleaning.
1) First remove dust, sand, or other hard minerals using a soft brush or cloth, bulb
blower or dry and clean compressed gas or air. If using a compressed air gun or a
cloth, use it very lightly.
2) Spray the lens with a dilute solution of mild (dishwasher) detergent and water. It is a
good idea to first spray richly and let the cleaner dissolve some dirt and let it drip off
naturally. Repeat if necessary. If the dirt is still sticking a stronger solvent might be
required, a 1:1 mix of isopropyl alcohol and water can be used.
3) Wipe the lens lightly and carefully with a clean microfiber cloth or a lens cloth,
repeating step 2) and 3) until the surface is clean. Cotton swabs / Q-tips can be used
as an alternative.
4) Rinse with water and wipe dry.
5) Do not touch the lenses with your fingers.
