Trex products are a composite of reclaimed and recycled wood and plastic products, such as sawdust, used pallets and plastic shopping bags. These composites are extremely durable and resistant to damage from sun, water or insects. Decks made from Trex composites are easy to care for and typically need thorough cleaning twice a year. You can use soap and hot water with a soft brush to clean Trex decks, or one of several cleaners specifically designed for composite products.
Corte-Clean is a powerful but eco-friendly cleaning product that is specifically formulated for composite materials, such as Trex. According to the Corte-Clean website, the cleaner will remove stains caused by mould, mildew, leaves, needles, clay, rust, grease, oil, sunscreen and food. It is biodegradable, nontoxic and noncorrosive, and does not contain chlorine bleach or sodium hypochlorite.
