801 Degreaser will leave no oils or residue on the mesh. Simply apply with a clean pad or brush dedicated to degreasing screen mesh and replace the pad or brush periodically. Scrub both sides of the screen with 801, rinse mesh, and frame edges throughly with water.  801 will help control water hardness, promotes emulsion adhesion, and reduces fish-eyes and pinholes.  801 is available in gallons, 5-gallon pails, and drums. For more information on drums contact us at by phone at 1-800-551-5524 or at sales@screenworkssupply.com.
