Now I use it on my Optoma lens and it removed part of the lens coating, blurring the lens. How would a non-technical consumer know this? I think that's negligence on the part of the manufacturer. I was diligent enough to purchase a lens cleaner for sensitive photographic equipment, you would think that would be sufficient, but I ended up with a severely damaged lens. I'm not sure how that's considered unscrupulous.
I'm assuming that you're talking about this Zeiss product widely sold at the Walmart Optical Department.
The MSDS for Zeiss Lens Wipes lists the composition ingredients as Ethanol Alcohol, Isopropyl Alcohol, and Water.
You can find the MSDS here: http://www.physics.purdue.edu/primel...ng%20wipes.pdf
I simply know of no lens coating used today that will be damaged by a combination of Ethanol/Isopropyl Alcohol in solution with water. Alcohol based cleaners will or can leave water residue behind, streaking, as the alcohol evaporates.
Professionals use acetone or a solution of acetone and methanol to clean a lens and manufactures use CO2/dry ice to clean a lens. I did not suggest these as they require specialize equipment or careful technique to implement.
The only way that I know that you could remove the lens coating with the Zeiss Wipe is to very aggressively rub the surface. Any lens tissue or micro fiber cloth will have an abrasive action if used aggressively. Zeiss lists a caveat emptor
warning on the packaging prefaced as "Advisory" ... test a small area first ... And as I stated, the Zeiss Wipe tends to leave water residue behind on the lens surface.
Perhaps you have mistaken the lens coating for what you saw as a dirty lens? Even if you rubbed the coating off, the lens would still work all be it with a change in contrast.
You said, "I did research extensively...
". I'm not sure what "extensively" means as a simple Google search for clean camera lens
or clean projector lens
gave me 16,900,000 and 1,180,000 hits respectively. Quickly perusing any of these hits gives advice similar to or mostly the same as I gave you.
As far as scruples go, I thought I made myself clear; If you buy something and damage it through your own misuse or negligence and then attempt to return/exchange it during a grace period without informing the seller or manufacture of the damage, I consider that unscrupulous or even dishonest. The seller or manufactures return/exchange grace period is always prefaced by a caveat with words to the effect that the product be returned in new condition with ordinal packaging, etc..
Not trying to be hard on you but such disingenuous behavior as you're alluding too simply drives up the price of goods and services for everyone else. Besides that, would you be happy taking ownership of what you thought was a new projector only to find out that you got one that someone spat on?
