I am getting black stains on my patio from water running off the roof. I do not have gutters installed on that side of the house yet. Does anyone know how to remove the stains? I'll get the gutters installed soon but still need to clean the concrete.

Thanks

Thanks

My husband tried all kind of cleaners, ....and he did lots of scrubbing, but nothing worked well. Then he used a power washer and it got almost all of it off. Hope this works for you.

Try this cost about $5 at Ace in Spanish springs works great

I used " Simply Green " from Home Depot . Put some on and brush around and let sit a couple. Brush some more and hose off. You buy in gallon container and can be used on other cleaning.
