I did this trex washing last year - typical hand brushing with good strength bleach and detergents. It was really bad - included lichens on the handrails on top of the deep seated mildew.
Anyways - customer calls for a 'maintenance' washing - so this time it's all downstreamed. I couldn't believe how bad the mildew had gotten in a year's time. They thought it still looked pretty good - even I thought so - but when the bleach started going on and I started looking closer in certain corners - it was downright ugly! Some areas needed 5-6 consecutive applications - a few spots were so bad they didn't come out at all!
And this was just a year after I brushed the entire decking and got it spotless! I would have never thought that even on trex - that the mildew would have returned so soon?
