Maybe it's from the 4th of July.
It’s probably mold. Power wash it.
Mae just didnour front stoop and was amazed at the difference from a year ago. We had some spots too. Just prism water will do.
If you don’t have a power washer try a stiff brush and some hot water.
Have you tried pressure washing it?
Is it oil based? try cat litter to soak it up? Then follow with a powerwashing. Have you tried just bleach and a strong brush?
Wire brush and some soft scrub or CLR.
