I researched one morning, the best way to clean my Trex Decking. After reading several stories about what didn’t work, I decided to try Corte Clean because of the environmental concerns of other products. I am so happy we tried this product first. There are many stories of people who have tried other products and wasted so much time, money and effort! Our deck look FABULOUS! I am thrilled and will use this product and will use it every year!
