Product Care & Maintenance

  • Denali Stainless Steel Plates: To maintain the polished finish, clean the plates regularly with a soft cloth and a mild detergent cleaner. Avoid abrasive materials or harsh chemicals that could scratch or damage the surface. Rinse thoroughly with clean water and dry with a soft cloth to maintain the polished finish.
  • Virgin Rubber: Clean the rubber portion using a mild soap and water solution. Avoid harsh chemicals or petroleum-based cleaners, as these can degrade the rubber over time. Rinse thoroughly and allow the mud flaps to air dry for the best results.
