Trusscore products have a smooth, non-porous surface that can easily be wiped down, pressure washed, or disinfected. For day-to-day cleaning, we recommend washing the panels using a sponge or soft cloth and a mild cleaning solution. If dirt is difficult to remove, we recommend cleaning the walls using a solution that contains 1/3 cup of laundry detergent (e.g., Tide), 2/3 cup of tri-sodium phosphate (e.g., TSP), and 3.79 liters (or 1 gallon) of water. If hand washing doesn't get the job done, try pressure washing. To safely pressure wash Trusscore products, we recommend: Using a small- to mid-size power washer with less than 3,000 psi Using a wide spray nozzle angle (40° or greater is preferred) to distribute the water pressure across the wall Keeping the power washing nozzle at least 4 to 6 feet away from the wall at all times For more information on how to properly clean and disinfect Trusscore products, download our Cleaning & Disinfecting guidelines.
