This matting is what is used in custom sportfish yachts. This style is heronrib, 36" wide, and sold by the foot.
Heronrib has both anti-bacterial and anti-fungal additives to protect against fungal and bacterial contamination, but regular cleaning is also recommended to remove light grease and oils, food fat, wax and acrylic polishes.
Check the matting is free from any loose items like litter and clothing fibers.
Regular hand cleaning should be done as required, using an alkaline cleaning fluid as per the manufacturer's instructions. The matting can be cleaned in position – simply apply the cleaning solution with a sprayer or mop and allow to penetrate any grease or dirt. You can then use a stiff deck brush to work the cleaning fluid into the surface dirt. Allow to soak before rinsing with clean water.
If you're deep cleaning or cleaning the flooring below, the mats should be rolled up. They shouldn't be folded or pulled or dragged, as this will damage the matting over time.
How frequently you machine clean will depend on how much traffic the area gets. Spray the surface with the alkaline solution and then, using a cylindrical brush machine, clean the top surface in the direction of the top ribs. If there's an etched pattern on the top ribs where dirt can easily collect, make additional cross passes to ensure a thorough clean.
If the underside of the matting also needs a clean, roll it up and then roll back out, leaving the underside facing upwards. Repeat the spray and above cleaning instructions.
Any type of steam cleaner can be used. Good results have been obtained with nozzle pressure of approximately 1000 lbs p.s.i. (6894.8 kN/m²) and water temperature of approximately 212°F. Cleaning fluid should be diluted according to the manufacturer's recommendation.
