FIRST, we recommend you try to remove anymaterial from the lens by blowing it off with clean, dry deionized air.DO NOT use any liquid to clean the lenses.A TorayseeTM cloth is included with the lens kit.Proceed as follows :1. Always wipe lenses with a CLEAN TorayseeTM cloth.2. Always wipe lenses in a single direction. Do not wipe back andforward across the lens surface as this tends to grind dirt into thecoating.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. Smearsare the first indication of a dirty cloth.5. Do not use fabric softener when washing the cleaning cloth orsoftener sheets when drying the cloth.6. Do not use liquid cleaners on the cloth as doing so will contaminatethe cloth.Order number for a new TorayseeTM cloth : R379058.Other lenses can also be cleaned safely with this TorayseeTM cloth.Cleaning procedure for the other HD lensTo minimize the possibility of damaging the optical coating or scratch-ing exposed lens surfaces, we have developed recommendationsfor cleaning lenses. FIRST, we recommend you try to remove anymaterial from the lens by blowing it off with deionized air or lightlybrushing it with a soft, camel's hair brush.Plastic lens with multilayer coatings & all glass lens elements.1. DO NOT spray any type of fluid directly on the lens surface.2. DO NOT use any dry material to clean the surface (dry rag, tissue,etc.)3. Use a commercial liquid window cleaner. DO NOT use anaerosol. Other cleaning agents, such as laboratory-grade ac-etone or a 70-30 mixture of ethyl ether and ethyl alcohol may alsobe used. If you are not sure of the cleaning agent, experiment witha small area of the lens first.4. Use a soft cotton cloth (cotton diapers laundered several times toremove sizing) or any soft facial tissue (Charmin, Softweve, etc.).5. When using window cleaner, moisten the cloth or tissue andlightly wipe the surface. Then lightly dry with a new tissue.6. When using acetone or ethyl ether mixture, proceed as follows :Fold the cloth or tissue several times to form a pad. Soak the foldedend of the pad in the acetone. Starting at the diameter opposite you,immediately wipe the coated lens, with very little pressure, towardyou in a straight line and off the lens. Do not stop with the tissueon the lens. Wipe at a speed that is equal to the evaporation rate.This is very important to prevent streaking and spotting. Start yourwiping at one side of the lens and, with successive wipes, moveto the other side. Turn the pad over for each wipe, then inside out.Do not make more than one wipe per clean area of pad. Be carefulof the painted edge, since acetone will soften it.
