Review on PNR16OZ-08 Edgewater Industries 16 oz Oil Stain Remover by Lisa Barber

Amazing product that really works. I smeared this on an old oil stain in the driveway and the stain was almost gone. And we're talking about a stain that's been around for YEARS. However, I used the "I forgot" method, which means I left the product on the stain for over a week before removing it. I think it has something to do with the front of my car completely covering that spot and preventing me from seeing this little project in progress. When I finally remembered and brushed the powder off with a broom, the results were extremely impressive. I didn't buy a bottle big enough to cover the entire stain so I just grab a larger bottle and apply and sweep until I'm happy with the result. With an oil stain that has penetrated the concrete and then survived 4 seasons for many years it is probably realistic to say that you will have to treat the stain more than once but eventually this product will remove the stain from the concrete.
