Photographic Solutions Pec*Pads 4x4"-100 sheets are the ideal photo wipes for those who hate photo wipes! Pec*Pads are extremely strong, lint-free and pure (99.999%) that it is almost impossible to scratch an emulsion with them. They are so soft that they can be safely used to clean all types of sensitive surfaces: scanners, CD's, mirrors, lenses, telescopes, etc. When Pec*Pads are used with PEC-12, they are ideally suited for cleaning photographic film and print emulsions.
