Its not a trex deck, is the newer ones I believe PVC? Vinyl? , we softwashed the deck and when we finished we found 3 stains that look like this. Any recommendations, the guy really wants them out, but I have no idea what to try. I also tried gutter grenade on it. Any help would be great.

Danny Does he know what the stains are from? If organic, BT200, agitate with a stiff brush a bit, let it sit and do it's work. Rinse and if still there leave a light coat of BT200 behind and let them eat overnight.
