The Frontrunner entrance flooring system should be cleaned on a daily basis by vacuuming with an industrial cleaner, preferably using a driven brush to agitate the pile of the absorbent inserts. Should stones, salt particles or other solid matter become embedded between the surface ribs, remove using a blunt instrument (screwdriver) or similar device.
As with all entrance flooring systems chewing gum poses a threat to the effectiveness of Frontrunner. Consequently, in addition to daily routine above, it's important to remove chewing gum deposits and stains as they appear. Failure to keep up regular gum removal may attract further deposits.
Either; Manual Dry Cleaning - Clean the top surface using a long handed deck scrub or similar brush that will not leave fibres on the mat. Be sure to scrub in both directions to clean the top ribs as well as the tread surface of the PVC grid. Apply a "Dry method" cleaning compound to surface of mat. Brush and agitate compound in all areas of mat until compound is fully absorbed. If possible leave for 30 minutes then vacuum and brush until all compound is removed.
Or; Machine Wet Cleaning - Follow cleaning instructions for machine used. A cylindrical brush machine is seen to give the best results. Initially work in direction of top ribs then across the ribs to complete cleaning. Where a cylindrical brush machine is not available equally good results can be achieved using a high-pressure water extraction process. In areas of abundant salt build up, apply a pre soak solution of vinegar and water (1:20 mix) to the surface prior to machine cleaning.
