Linecos Document Cleaning Pads are recommended for removing dirty fingerprints and cleaning dusty or dirty paper items. These pads contain a soft, grit-free powder that absorbs and cleans surface dirt from paper. To Use: Twist the pad lightly over the soiled document to produce a thin layer of white cleaning powder. Then, gently rub the pad over the area to be cleaned. This action causes the dust and dirt to be absorbed by the layer of cleaning powder. Once the area is clean, simply brush the residue away to reveal a clean, renewed appearance.
