Anybody use Optimum Power Clean on a composite deck?

[newb001]

Just wondering if anyone has tried OPC (or some other all purpose cleaner, or even car wash) in their pressure washer on a composite (I have Azek) deck.

I have a spare piece so I'll test on that first, but just wanted to see if anyone had safely used any auto cleaners on their composite deck.

Thanks.

How big is your deck? I have Azek on my dock and I just go over it with a boat brush and the left over soap and water after I wash my boat weekly. It keeps it looking good and only takes 10 minutes.

It's around 325 sq ft. Figured I'd use my pressure washer and the built-in dispenser, along with maybe a rotating brush. Just wasn't sure if I should buy a deck-specific cleaner, or could try some of the stuff I already have.
