Hi,
I have a concrete deck around my 15 year old pool. It is holding up very well, with a couple crackes that developed at one end the first winter(settling), but the crackes are tiny and not a problem.
My question is that in one corner under an evergreen the concrete has turned a little blackish. And around the rest of the concrete it is a bit dirty looking.
What do you people think would be the best way to clean this up. I was thinking mixing some bleach and some kind of soap, and making a solution and trying to scrub it. What do you people think is the best thing to do. I really donèt want to fool with muriatic acid and then have to re-seal the concrete.
I await your answers. Thank you very much.

Hi George,

Me too. The Marine thing!!

Hand scrubbing as you mentioned will work, but it is hard work.
A pressure washer will do the job, however it is difficult to prevent 'zebra stripes'. The perfect way would be a surface cleaner pw - looks like a floor polisher. It has a spinning dual outlet under the deck.
I do not know if they are available at tool rental outlets or not. You could call around.
