Is it concrete or blacktop? I'm guessing concrete. If so, I think it would be quite safe to power wash it.

I powerwashed my driveway. A few days later two other neighbors saw the after-effect and cleaned theirs. It definitely brightens the color and in a five-year-old neighborhood, you can spot my drive from a bit up the road! It removed clay stains, oil drips, and leaf stains.

Thanks ladies! I used to power wash my old driveway, but I just wasn't sure if it is too soon to do the new one. Yes, it is concrete and I heard somewhere that It should be a yr. old before power washing it, but I guess it is close enough!! :)

chloedaven: What PSI is your Pressure Washer?? I no longer have access to the old one I used to use, and I cannot remember how powerful it was! Would a 1750 PSI be powerful enough for the driveway and deck??

You won't hurt your driveway. I purchased my power washer when my concrete driveway was three months old and I wash it every week or two. I hit it hard in places with stubborn stains and it has caused no damage.

My neighbors had a sealer applied to their concrete driveway.
