The Parker’s Perfect has nothing to do with Spider-Man’s favorite dish in the local restaurant as the name might suggest, but instead is a lens-cleaning towelette that leaves a protective film on the surface of the lens. In addition to stopping the lens from fogging up, the film protects it from scratches, dust and fingerprints!
Note! Before wiping, make sure the lens is clean of dust or dirt. Otherwise the small pieces of sand might make grooves on the lens and give water something easy to latch on to. A good professional tip is to wash the lens with a lot of water and dry it before using the towelette.
