How to Remove Oil Stains From an Asphalt Driveway

Oil stains on asphalt driveways aren’t just unsightly—they can get tracked into your house or in your car. Removing oil stains from your asphalt driveway isn’t in the least like wiping up a food spill on your kitchen floor. Instead, you would like to regulate your methods and use greater force together chemically that effectively hack the oil.

Basics of Cleaning Oil From Asphalt Surfaces
Even before you start, you’ve got a plus. Asphalt is an impermeable surface—less porous than concrete. Since asphalt sheds water, it also features a tendency to shed oil stains.

You can hack old oil stains from asphalt with force, chemically, or with a mixture of the both. Force comes within the sort of a pressure washer, a nylon scrubbing brush, or a wire brush. Chemicals are either petroleum-based or they will be environmentally friendly degreasers.

Once you’ve got choppy the stain, the residue must be moved off of the asphalt driveway. Leaving the residue in situ will only re-stain the driveway after it’s dried.

Pressure Washing

Do-it-yourself pressure washing an asphalt driveway will hack and wash away oil stains. Pressure washing is pure force and it is a force to be reckoned with. Sustained pressure washing with a needle-thin spray won’t just hack the oil but potentially can hack the asphalt, as well.

So, hitting the asphalt with just the proper force may be a delicate balancing act. Pressure washers within the 1,600 psi range or less might not be ready to remove the oil stains. you will need a better pressure machine within the 3,000 psi range to effectively remove the oil.

Experience and better tools separate do-it-yourself pressure washing from professional work. For cleaning oil stains, professionals will use a special flat surface cleaning head that appears very similar to a floor buffer.

Water pressure up to 4,000 psi elevates the massive cleaning head, delivering up to eight GPM. Professional pressure washers can remove even the worst oil stains with this tool, all while preserving your driveway. Because the force isn’t as directed as a needle-thin spray, there’s little danger of ending the asphalt.

Green Degreasers
Most green degreasers use alcohol ethoxylates as their active ingredients. Some green degreasers also include citrus for improved cleaning ability and for a pleasing odor.

Green degreasers are often used either at full strength (directly from the bottle) or diluted with water. For oil stains, green degreasers require vigorous scrubbing with a nylon brush. Follow by washing away the residue with water. Several applications could also be necessary to completely remove the oil stains from the asphalt.

Oven Cleaner
While oven cleaner definitely falls within the toxic category—it contains lye, ether, glycol, and other poisonous chemicals—it will hack the oil stains on your driveway.

Spray the stain with the oven cleaner and let it foam up and sit for about a quarter-hour. Use a wire or nylon brush to wash the stain, then wash it away.

Granular Clay
Bags or buckets of fine granular clay are sold for the aim of absorbing oil and other fluids on the pavement. Granular clay is best on fresh, standing pools of oil. Old, dried oil spots generally won’t be cleaned off with absorbent.

Scoop the granular clay onto the oil spill, then spread it with a brush. Maintain a thickness of 1/2-inch to 1-inch to completely absorb the spill. Once the oil has been absorbed, sweep up the absorbent, and eliminate it.

Cat Litter
Cat litter absorbs and cleans oil stains from asphalt very similar to granular clay because it’s also based largely on granular clay.

“Granular clay and cat litter can also be used as preventative measures, before oil spills. Just opened up 1/2-inch or more of the merchandise under the situation (such as an engine block) where you expect the oil spill to occur.”

When using cat litter to wash oil from your asphalt, make certain to use the clay-based litter. don’t use colloid or biodegradable cat litters made up of newspaper, corn, wheat, or pine.

Cat litter offers the advantage of being fast thanks to mopping up oil spills from asphalt since many households have already got cat litter available. If you plan to use cat litter over the long-term, switch to the pure granulated clay product. Cat litter is way costlier than granular clay.

Penetrating Oils
Low-viscosity spray penetrating oils like WD-40 or Liquid Wrench can clean oil stains from asphalt driveways because they’re petroleum-based. These products are toxic, so take care when using them. While they’re effective, they’re also an upscale method because such a lot of the merchandise is required.

Baking Soda
Baking soda can do almost anything. But is it up to the task of cleaning oil stains from asphalt?

Baking soda has no special chemical properties that hack oil. Simply put, bicarbonate of soda may be a mild abrasive. Combined with water and a scrubbing brush, bicarbonate of soda is moderately effective at ending those oil stains. Use only a touch of water so as to form a paste.

Baking soda also can be used as an absorbent, very similar to granular clay or cat litter. But baking soda’s finer grains are harder to get rid of from the asphalt.
