Lens cleaning (Page 5): I had checked the MSDS for Purosol before my previous post, but found no components listed. Only that it has no hazardous materials. This is a relative term.

I had checked the MSDS for Purosol before my previous post, but found no components listed. Only that it has no hazardous materials. This is a relative term. Not hazardous materials for humans. How about for lenses? Am I missing something?

My guess is that it's probably OK -- gets high praise here -- http://www.edmundoptics.com/lab-production/cleaning/lens-cleaners-pouches/purosol-optical-cleaner/2520

Purosol, sounds like snake oil to me. I am always wary of a product with secret ingredients. This stuff could ruin your front element, eat away the filter threads, and cure nail fungus. I think you should apply at your own risk. Getting close to 5 pages. Just make a decision, and buy the Zeiss lens wipes, and shoot the horse.

Sbesaw, does the manufacturer recommend anything. Maybe that would be the way to go. Check your manual or call them. They may recommend one over the other. Just saying.

I fully agree with you. Because of that distrust that we share, I checked a little further. In Amazon, where there are customer reviews, Purosol ratings are here:

http://www.amazon.com/Purosol-Natural-Lens-Cleaner-4oz/dp/B000W8OZE2

Of a total of 72 ratings, about 20% are either one or two stars out of five stars. I consider those truly negative. I generally pay attention to those because the five-star ones are more likely to include some where a vested commercial interest may have played a role although most reviews sound reliable. Please, go to the URL and read the comments from people using th substance for reading glasses, a far less valuable article than a camera lens.

You have to take negative reviews with a grain of salt as well as those positive ones. Too many times, a person may use a product incorrectly & then give it a negative review due to their own stupidity. I look for a common thread amongst the negative reviews to get a better idea rather than just the number of negative reviews. Can't tell you how many times a person will give a product a negative review because it didn't have a certain feature when the product never claimed to have that feature to begin with.

Speaking of lens cleaning -- here's an interesting article from LensRental.com about their cleaning process. I'd guess they clean more lenses than any one (or dozen) of us will. Interesting read -- http://www.lensrentals.com/blog/2011/05/the-lensrentals-lens-cleaning-methods

According to their MSDS, the ROR product contains Amonia as well other ingredients. http://www.ror.net/wp-content/uploads/2009/09/Material-Safety-Data-Sheet-JUNE-20121.pdf . I'd be a little reticent about using something with Amonia for coated camera lenses.

I do take those factors into consideration.When the bad ratins start getting above 10% I start scrutinizing thing more carefully. In this case, the percentage is high; here is a fragment of one of the comments:

<<Finally, I thought maybe there was some residue from a previous cleaner that Purosol couldn't remove, so I tried washing my lenses in soap and warm water first. When I dried them, they were crystal-clear. When I subsequently cleaned them with Purosol, the film came back.>>

I would prefer not to test the accuracy of that rating on my lenses when there are other products with a truly good record. And as it has been mentioned, I don't trust products where the manufacturer doesn't give any details and expects total trust from the customer while keeping him in the dark. By the way, the "totally natural ingredients" perhaps could include the purest virgin olive oil, and yet I wouldn't want it on my lenses.

I have seen reference on here a number of times for Zeiss lens claening tissues from WALMART. I went to WALMART this AM and they could only find Bausch + Lomb Premoistened lens cleaning tissue 50 count for $ 2.97. Contains Isopropyl Alcohol.

Are these the same? Any issues with tissues moistened with Alcohol?

I just order mine from Amazon. Absolutely love them!

So what is the definitive word on using alcohol impregnated wipes on Nano Coated $2,300 Nikon Lenses?

Most I can find is that nano coating is fragile and is only applied to internal lens elements. Should be okay to clean same as other lenses. Just be sure it's a clean T-shirt. ;)

HEY GUY'S! Although alcohol is known as a great cleaner it is also known to leave a film behind if alowed to dry on the surface and should be wiped off with a dry lens cloth before it does.

OK, this is only a repeat of what the camera shop owner said to me and it does make sense. IMO. Go get a box of "Q-tips" then get the stuff called "PUROSOL" Lens cleaning kit. It's safe, No alcohol, No Ammonia and the biggest thing he said "It leaves no residue". Anyway, take a q-tip, spray 1 squirt on one end, start in the- center of the lens or filter (whatever your cleaning) rub it in a circular motion. Then flip the Q-tip over with the dry side and start wiping off the liquid. You will use 3-8 Q-tips depending on the size of your lens. His explanation of the procedure is this: If you use any type of cloth, the second you pick it up, you contaminate the cloth with the oils from your fingers. then if you use it more than once, you are probably going to scratch the lens with the dirt you wiped off the last cleaning. I am in no way trying to sell this product, but I really like it and the anti-static that it seems to have, makes my lenses not get as dusty.
