Purosol All Natural Lens Cleaner 1oz.

Aware that Purosol Lens Cleaner got previous high marks for use in cleaning eyeglasses and camera lenses as well as eyepieces and monitor screens of camera bodies, I turned to an expert in microscopy for his opinion on how Purosol Lens Cleaner works on microscope lenses.

The following review is by Dr. Steven Ruzin, Director of the Biological Imaging Facility, University of California, Berkeley, and also the person in charge of the Golub Antique Microscope Collection:

"Purosol All Natural Optical Cleaner is a slightly viscous liquid sold as a solvent-free optical glass cleaner. They state that it cleans by breaking molecular bonds of dirt particles. For eyeglasses and microscope eyepieces this cleaner does a fine job of removing dirt, smudges and mascara. However, because it is an aqueous solution (as opposed to an organic solvent) it is inadequate for cleaning microscope objectives. When used on an Oil Immersion objective the Purosol forms what looks like a colloidal salad dressing on the surface of the lens. Purosol does not remove immersion oil and does not clean the lens. While it looks to be a good solution for cleaning more conventional optical surfaces, Purosol is inadequate for cleaning microscope objectives. My recommendation is to stick with chloroform for removing immersion oil from objectives and perhaps use Purosol (or ethanol) for eyepieces."--Steven Ruzin, UC Berkeley

I purchased a bottle of Purosol Optical cleaner upon the recommendation of a Nikon rep for cleaning my expensive Pro glass. The product works wonders, it removes finger prints, water marks, pollens etc. completely and without streaking. As a few others have mentioned the cloth that is part of the kit can leave lint behind, but I have found that the Kinetronics Panther and Tiger cloths do wonders in combination with Purosol.

Unlike many of the cheaper lens cleaning products Purosol does is *not* solvent based. The solvents in these products run the risk of damaging lens and filter coatings. I was more than happy to find an effective quality cleaner that would not pose a risk to those coatings on expensive lenses and filters.

I've tried all of the major brands (and some of the lesser known ones too), and this is hands-down the best lens cleaner on the market. Most other cleaners leave a film or streaks on the lens. Applied correctly, this leaves your lens crystal clear and clean. No streaks, no film. If you've spent a lot of money on good glass, don't scrimp on the cleaner.

Does exactly as advertised - cleans camera lens like a champ (and my glasses too). The nice benefit here is there are no nasty fumes or odors from the cleaning solution. I few spritzes and glass and plastic cleans up wonderfully. I sense that the bottle I have will last a good long time.

You spray it, you wipe it down and it leaves no streaks. I don't know what else I can say about the product other than that it works and it works well. It's all natural which makes it a better buy for the "green" conscious person, I suppose. It's in my camera bag now and I've used it several times and it has performed unfailingly each time.
