Review on Pour N Restore Oil Stain Remover 32 by Heather Johnson

I have used this product several times to remove oil stains from concrete driveways and porches. Could never restore original color. The application is very simple, but it takes several hours to a whole day to dry completely. When the material is completely dry and the odor is gone, it can be washed or scraped off and collected with a vacuum cleaner. You may need to use it two or three times to get perfect results, but persistence pays off in this area, as in most others.
