To wash the test area, use a pad of 28/24 mesh cheesecloth and distilled water and a mild detergent cleaner, Wet the cheesecloth thoroughly with the cleaning solution and rub it, using moderate hand pressure, over an area of the sheet approximately 4”x 4” Care must be taken to avoid any scratching, burnishing or other physical alteration of the coated surfaces. After washing, as described above, flush off the test area with distilled water and allow to air dry.
