Alternative Procedure A
To clean lenses that are extremely sensitive to mechani cal stress or
pressure you can also use an optical clean polymer film. This procedure is
time consuming, but you avoid scratching or destroying the surface.
1 Put the film on the surface and wait at least 30 minutes to make sure
that the film has had enough time to dry.
2 Remove the film and any dirt with special adhesive tapes.
Alternative Procedure B
If your lens is sensitive to water then
1 Moisten the lens or the mirror with isopropyl alcohol.
2 Take a new, dry soft tissue and remove the alcohol, dis-solved sediment
and dust, by rubbing gently over the surface using a small circular
movement.
3 Blowaway remaining lint with compressed air.
