Although TND products are low maintenance, TND recommends periodic cleaning to help maintain the natural wood grain of the product. For best results power wash using dish soap detergent. The recommended maximum pressure is 1700 psi for TND decks. A fan tip nozzle must be used along with the proper cleaning product. Spray in the direction of the brush/grain pattern to avoid damaging the product. Use caution not to damage the material and always take the proper safety precautions when operating a power washer.
