[0.19 lb] Found Pursol quite useful for Telescope mirror cleaning too. Does not leave streaks too.

[0.19 lb] This is by far the best optical cleaner on the market.
This is also an earth friendly product .
No harsh chemicals and contains organic ingredients .
I use this on all my camera lenses and my eyeglasses as well,

[6 x 5 x 1.55"] I've used this on plastic eye glasses, microscope lenses and camera lenses. I never worry about harming the optical coatings.

[6 x 5 x 1.55"] I've used this cleaning solution before. It works very well on all my optics. Got this as a travel size.

[6 x 5 x 1.55"] This was recommended by a friend, and it has been a great discovery for me.

[6 x 5 x 1.55"] use Q-tips to apply, use Q-tips to dry. I just didn't get results with micro-fiber. streaks & haze are left behind. Instead, apply with a Q-tip, then use a clean & dry Q-tip to dry in a circular 'polishing' motion. Be patient, and you'll be amazed at the results. small lenses can be done in single application, larger ones should be done a section at a time. (a 14-24mm F2.8 requires 4 to 5 sections to be done, each with fresh Q-tips. Q-tips are CHEAP. use as many as you need. Best results I've EVER gotten, and no need to change.

[6 x 5 x 1.55"] I use this NASA-inspired product among my 3 camera bags.

[0.19 lb] This spray is easy to use, non-harmful, and gets rid of all the small smudges on my equipment.

[0.19 lb] This isTop shelf and very easy to use. Purosol more than lives up to all the claims I've read and it seems to work like magic with little effort and hardly any pressure on the lenses. First, Blow the lens clear of any dust and make every attempt to not ever actually touch the lens surface. Make a decision as to rather the lens really needs to be cleaned or not. If You then find that You must clean use this liquid lens cleaner. Never attempt clean a dry lens! I've not tried all the available lens cleaners; but, I do like Purosol. Not a streak to be seem after use even in the beam of very intense light.

[6 x 5 x 1.55"] This Purosol Lens Cleaner is the second product �from Purosol �that I've bought. �The first is Purosol Plasma flat panel screen cleaner. �I ordered the Lens Cleaner based on the performance of the Plasma cleaner. The Lens Cleaner works just as well. �I think they are the same product. �But, I have not checked the Material Data Sheet. �It will list chemicals but not exact percentages. The interesting issue is the Lens Cleaner is is in smaller packaging (4 ounces versus 16). �Of course flat panels have more area so the big bottle seems right. �And, the cost per ounce of the Plasma is the same unless you buy the large 16 ounce Plasma. �Otherwise the cost is the same. �Lens cleaner: 1 oz $8, 2 oz $13, 4 oz $ 16. And the Plasma: 2 oz $13, 4 oz $16, 16 oz $30. �But, it lasts a long time. �So, the cost per application is OK. �And, would one cut corners on the cleaner cost and risk the optics? �The Lens Cleaner is shown as just "Optical " in the B and H site photos. �The product, 7 27854 1000307, is "Lens Cleaner" on the label.
