My pool was installed 9 years ago. It was and is my first pool, and while I educated myself on overall project cost, I just rolled with my contractor’s defaults in terms of decking, which was Kool Deck.
I am fine with the Kool Deck, other than cleaning it. We have a large wooded lot, and we live in a warm humid climate, so I expected there to be some organic buildup in the cracks and crevices, aside from just dirt.
I keep the deck swept, and don’t let pine needles, leaves, etc. sit around for long. But every year, the grime gets darker and the buildup gets more stubborn. I have tried the power washer with the deck-cleaning attachment, I’ve tried the power washer without the deck-cleaning attachment (though I’ve never tried the 0°/15°/25° nozzles out of fear of blasting off the Kool Deck coating), I’ve tried Wet & Forget, and I’ve even tried full strength roof algae cleaner. Nothing makes much of a dent.


As you can see, it’s really starting to look gross, and worse, some areas are starting to get slippery. Which I cannot have.
I am not sure what else to try, but would be grateful for any constructive suggestions beyond what I’ve already done.
Please and thank you.
