    Wet n' Forget applied liberally to surface on an overcast day without chance of rain for at least 5 hours.

    Dawn liquid dish detergent poured directly on stains, scrubbed in, then left to set for 30 minutes. Scrub again with a soft bristled brush or shop broom, then rinse thoroughly with cool water. Repeat as needed.

    Some people have successfully used power washers, but you must use caution, as the pressure can damage some concrete surfaces.

    Hello Linda,

    We have a newer concrete driveway that sometimes gets abused by contractors or service personnel. We try to observe and remove these oil stains ASAP. We use TSP for large areas or areas not treated immediately or this Easy off spray for stains we catch right away. Scrub with a stiff plastic kitchen type brush and rinse with water. Remember to wear personal protection as labels might direct.

    I hope this helps.

  • If it's a grease stain, you can use a combination of kitty litter and coca-cola:

    If it's something like a rust stain, you can try vinegar first. If that doesn't work, try muriatic acid. It gets about any stain out of concrete. But it's very caustic. It needs to be diluted with water and you have to wear gloves and eye protection when using it.
