Compressed air.
•
Clean Toraysee® cloth or any micro
fi
ber lens cleaning cloth.
•
Clean cotton cloth.

Lens cleaner (e.g. Carl Zeiss lens cleaner or Purasol® or any water-based lens cleaner)
How to clean the lens?
1. Blow off dust with clean compressed air (or pressurized air cans
1
) .
2. Clean with lens cleaner together with a clean lens cleaning cloth to remove the dust and contamination. Use big wipes in one
single direction.
Warning:
Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Use a dry lens cleaning cloth to remove left liquid or stripes. Polish with small circles.
4. If there are still
fi
ngerprints on the surface, wipe them off with lens cleaner together with a clean lens cleaning cloth. Polish again
with a dry one.
If smears occur when cleaning lenses, replace the cloth. Smears are the
fi
rst indication of a dirty cloth.
1. Pressurized air cans are not efficient if there is too much dust on the surface, the pressure is too low
