When oil collects on driveways, there are only two ways to get rid of it: wash it or turn it over to a horde of ambitious prospectors. Avoid the mess with this Groupon.
- $79 for a concrete driveway cleaning up to 16'x20' (a $199 value)
For driveways above 16'x20', the company assesses a $69 fee for every additional 10'x20' area.
Coyote Concrete Cleaning
Instead of brute force, Coyote Concrete Cleaning relies on science to remove stains from concrete. The outfit's technicians employ an enzyme solution—no water is involved at all—that penetrates porous concrete and eats away at deep-seated oil. Because the process creates zero water runoff and doesn't pose a health threat to pets or plant life, the Environmental Protection Agency gives the treatment its stamp of approval.
