I have a question regarding pressure washing a pool deck that I'm hoping you all can help me with. I'm in Florida and about once or twice a year I pressure wash my pool deck. I believe the material is called "Cool Create" or "Cool Deck" and I'm trying to get rid of a layer of what I am assuming is mildew.
After pressure washing with my bottom-of-the-line, Home Depot, gas powered pressure washer and allowing the deck to dry it looks almost like new. However, before it dries and when it gets wet again there is a hard to describe gray film (for lack of a better term) on the deck. Additional washing doesn't seem to get rid of it and like I said once it dries it looks great. The first time I did it, I thought I had washed the color out of the decking since it had a concrete color but it dried just fine.
The gray is very hard to describe. It's not exactly a film since it doesn't sit on the top. I am guessing...it is mildew that is stuck in the nooks and crannies but the gray color throws me off.
Is the gray mold or mildew that I'm not getting off with water alone or something else? I have never tried using bleach or any other cleaners or chemicals. I guess I am slightly paranoid of killing off my landscaping that surrounds the pool cage so I've stuck to just water. Does anyone have any suggestions? I've read thru a lot of the postings here and it seems a mixture of water, bleach, and some kind of detergent...sprayed on and allowed to sit is the way to go.
Also, I also get green mold and/or mildew on my pool cage. Any suggestions for keeping that clean longer? Again...I'm willing to dry out a bleach mixture but leery of spraying it since I have a lot of landscaping just outside the pool cage.
Thanks in advance for your help!
