Considerations before getting started
The following four factors contribute to the time and cost required to clean an oil stain in a driveway:
- Size of the stain: Larger oil stains will take more time and cost more to clean than smaller oil stains (yes, we are stating the obvious!)
- Age of the stain: The longer an oil stain remains on a driveway, the deeper the oil will soak into the concrete. Thus, older oil stains will require more potent cleaning solutions and more rounds of scrubbing than fresh or "wet" oil stains.
- Type of chemical stain: Cars can leak many types of fluid--oil, transmission fluid, brake fluid. While this article focuses on cleaning oil stains, different chemicals may work better on cleaning non-oil based stains.
- Weather: Warm concrete will generally react better to cleaning solutions than cold concrete. In addition, windy weather may cause cleaning solutions to evaporate quicker, allowing you less time to soak up the treated oil out of the concrete.
Also worth consideration is whether your car is continuing to leak oil. If your car is leaking oil and you have no plans to fix the leak anytime soon, you may want to consider setting an oil pan underneath your car. Many HOAs do not allow oil pans to be left in the driveway (when no cars are parked in the driveway), you may want to consider parking your car in the garage (at least until the leak is fixed). Otherwise, you may find yourself frequently moving the oil pan on and off the driveway as you leave and return home in your car.
Materials needed to complete the project
Generally, you will need the following items to clean an oil stain:
- Oil stain cleaning solution (discussed in more detail below) [cost = $4 to $10]
- Paper towels [cost = $2 to $3 per roll]
- Scrubbing brush [cost = $1 to $3]
- Rubber gloves (depending on the cleaning chemical used) [cost = $3 to $5]
Step-by-Step Instructions
Cleaning oil stains is a three-step process:
Step 1: Apply the cleaning solution to the oil stain
Step 2: Scrub the stain to ensure the cleaning solution is penetrating into the oil and top layer of concrete
Step 3: Soak-up the oil and cleaning solution mix with paper towels. [See Note A below]
Depending on the age and size of the oil stain, you may need to repeat the above steps several times. In our tests, those cleaning solutions that worked still required three or four rounds of "apply-scrub-soakup".
Note A: It is important to soak up (as opposed to spraying off with water) the oil and cleaning solution for three reasons. First, by spraying down the oil stain, you risk spreading the oil around your driveway and causing additional stains (albeit lighter stains) on the driveway, sidewalk and street gutter. Second, spraying down oil and chemical solutions into the street gutter is usually prohibited by law. Third, spraying down oil and chemical solutions into the yard (as opposed to the street gutter) will likely damage or kill plants and grass growing near the driveway.
Tip 1: It is usually difficult to see how well the oil stain cleaned up until after the driveway is dry. Wet driveways usually exaggerate the appearance of the oil stain.
Tip 2: On cold days, you may want to consider warming up the oil stained area by pouring hot water over the area (before you start the "apply-scrub-soakup" process). |
