Tried this for cleaning 35mm film and also to clean the scanner (Cannon 8800F) bed. 1) This is definitely not lint "free". Cleaned the scanner bed with a wipe just out of the packet while looking through a 8x magnifying loupe. I can see lint left behind. When used with PEC-12, noticed a thin film of whitish goo, probably from the wipe. 2) Tried using with PEC-12 for wiping negetives and again the results were not good. Left lint behind and also left minor scratches. So this is generally ok for wiping optics where a very small pices of lint is ok, but not for negatives.Get more detail about PEC-PAD Lint Free Wipes 4"x4" 100per/Pkg.
