A pressure washer can only be used for rinsing TimberTech [Composite Deck Cleaner](https://www.diyhomecenter.com/timbertech-deck-cleaner-1g). The recommended maximum pressure is 1,500 psi, and a fan tip nozzle should be used. Spray in the direction of the grain pattern, never across the grain or width of the board, to avoid damaging the surface of the deck. For additional information, refer to TimberTech's [Care & Cleaning Guide](https://1ox5gcnmxd11qsocs22jdm9n-wpengine.netdna-ssl.com/wp-content/uploads/2020/03/TT_Care_Cleaning_Guide.pdf).
