Proceed as follow :
1. Always wipe lenses with a CLEAN Toraysee

2. Always wipe lenses in a single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Do not leave cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.
4. If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty cloth.

cloth.
Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
