Surface Conditioning

After the layout lines are marked, M-Prep Conditioner A should be applied repeatedly, and the surface scrubbed with cotton-tipped applicators until a clean tip is no longer discolored by the scrubbing. During this process the surface should be kept constantly wet with Conditioner A until the cleaning is completed.

Applying Conditioner to Surface

From VideoTech Library VS-101

Cleaning solutions should never be allowed to dry on the surface. When clean, the surface should be dried by wiping through the cleaned area with a single slow stroke of a gauze sponge . The stroke should begin inside the cleaned area to avoid dragging contaminants in from the boundary of the area. Then, with a fresh sponge, a single slow stroke is made in the opposite direction. The sponge should never be wiped back and forth, since this may redeposit the contaminants on the cleaned surface.
