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
