Mildew or mold on Trex

[Ron in NY]

Hi all,

I had a new Trex deck built 2 years ago. It has a few mold or mildew green patches on it now, What's the best thing to scrub it with to remove them ?? I used to use a mixture of bleach & laundry detergent on my old pressure treated wood deck. Can I use that on Trex ???

My Trex deck gets some mildew every spring, often thick enough it almost looks like moss. I use the detergent/bleach mix with some TSP added where it's thick. Put it on warm, let it sit several minutes, then sweep it off before hosing. The heavy areas may require a repeat.
