30-6 Posted July 1, 2007 Report Share Posted July 1, 2007 I noticed a smear on one of my scopes lenses, I cleaned it with industrial alchohol on a soft cloth but it's still there. What's the best to clean then without any damage to the glass? Quote Link to comment Share on other sites More sharing options...
steve b Posted July 1, 2007 Report Share Posted July 1, 2007 I just breathe on the lens to fog it up and use a normal glass cleaning cloth (from sunglasses etc), this seams to work pretty well. Quote Link to comment Share on other sites More sharing options...

mry716 Posted July 1, 2007 Report Share Posted July 1, 2007 'BOOTS' the Chemists specs cleaner is fine as it has nothing in it that will damage the lens coating and gives good cleaning properties with smear free drying. I spray it straight on the lens and then always use a new Kleenex Tissue and never touch the part I clean the lens with. Tissues are cheap so use as many as nec but only one wipe each DO NOT turn over and rewipe that bit has the scratches in it ! . Quote Link to comment Share on other sites More sharing options...
ShaggyRS6 Posted July 1, 2007 Report Share Posted July 1, 2007 I use Camera Lens cleaner with some lens paper. Works a treat. Quote Link to comment Share on other sites More sharing options...
Holland&Holland Posted July 2, 2007 Report Share Posted July 2, 2007 Be sure NEVER to use a paper tissue ! Paper contents wood and scratches the lens. Quote Link to comment Share on other sites More sharing options...
martinl Posted July 2, 2007 Report Share Posted July 2, 2007 I second that. Never use paper/tissues. Treat your scope lens like a camera lense and you wont go far wrong, any good photography shop will sort you out. Quote Link to comment Share on other sites More sharing options...
M ROBSON Posted July 2, 2007 Report Share Posted July 2, 2007 If you have a source of compressed air then give the lens a blow first, you don't want to rub any dirt particles around your lens on the cloth, this could scratch the coatings. At work I use Kodak lens cleaning papers, Kodak lens tissues. Also cloths with solution on them (kind of like KFC clean wipes ), Zeiss lens tissues Cheers, Mark.

High Desert Hunter Posted July 2, 2007 Report Share Posted July 2, 2007 I tend to use either 99% pure isopropyl alcohol, or a lens cleaner and pure cotton balls. Lens tissues work fine, I just like the result with the cotton, and it is what was recommended by Leupold if not using their lens pen.

ChrisDavey Posted July 3, 2007 Report Share Posted July 3, 2007 My company build camera vision systems, and we use METHS typically as it evaporates well without residue. Iso Alcohol can leave marks even in high percentages ( bloom ) but good for stubbon stuff. As Holland&Holland stated - NEVER use normal bog paper, its fine for yer bum but not for lenses as it is 'sharp' and will abrade sodium coatings and contains chemicals such as chlorine which are undesirable. Look to RS Components for alcohol compatable lense wipes, or pre-loaded alcohol wipes in a re-sealable tube. Also the addition of aftermarket self cleaning coatings TiNitride while nice in theory WILL give rise to multiple internal reflections which may appear as bright shadows in the view finder Quote Link to comment Share on other sites More sharing options...
