I had the privilege of working several contracted "test" jobs with the Flood Co last year as they were developing their composite cleaner. I'm not a well known "EXPERT" to a lot of you in these forum circles, but I've been in business for 6 years and have come to learn a little about power washing. I can tell you hands down Flood's composite cleaner is by far the best product I've used to clean composite decking. They have the bleach formula down to a science. I don't know everything that's in it but I know it works....WELL
