Items needed to pressure wash oil stains
Oil stains can occur at any time. The longer it remains, the more difficult it is to remove. It’s best to have these items on hand the next time oil spills in your driveway.
Here are the items you need:
- Degreaser – This product ranges in price from $19 to $22 and is used to dissolve heavy grease and oil from transmission fluid, brake fluid, and stains from BBQ grills, among other things.
- Rags – This absorbs excess oil from new stains. Use old rags at no cost, or buy a 12-pack set for around $8.
- Cat litter, or baking soda – Costs $8 to $15 and is used to absorb excess oil from the surface.
- Heavy-duty scrub brush – You can scrub the surface after applying the degreaser, which is especially effective on older stains. It ranges between $7 and $20.
- Regular concrete and driveway cleaning soap or Dawn dish soap – Applied after the degreaser to thoroughly clean the surface before rinsing. The price ranges between $20 and $22. Pro tip: Avoid using just any dish soap because it may clog your pressure washer.
- Utility broom or leaf blower (optional) – You can use this to remove leaves and other debris from the surface in preparation for pressure washing. It can cost anywhere from $20 to $40.
- Sealant – An after-treatment product that helps prevent oil leaks, blood, and other sticky residues from becoming permanent on the surface. One sealant can cost between $26 and $35.
The total cost of the materials is between $119 and $162.
How to remove old oil stains from concrete
Now that you have the necessary supplies, the question of how to get oil stains out of concrete remains.
Here are a few steps to remove those pesky oil stains from your driveway, paving the way for a cleaner, more appealing curb appeal for your home.
1. Prepare the area
Remove any outdoor furniture, plants, toys, or other items during the cleaning process. Remove stones, leaves, and other debris with a utility broom or a leaf blower.
2. Cover the affected area with cat litter or baking soda
For new stains, use old rags to absorb excess oil before soaking in cat litter or baking soda for 20-30 minutes or overnight for larger oil spills.
3. Apply a degreaser
Put a generous amount of degreaser on the affected areas and allow it to sit for 5 to 10 minutes.
Then, scrub the stain in a circular motion with a heavy-duty brush to distribute the product. This step ensures that the oil and grease break down for easier cleaning.
4. Apply a cleaning soap
Apply soap for 5 to 10 minutes, depending on the stain, using regular concrete and driveway soap or Dawn dishwashing soap. If your soap is concentrated, make sure you dilute it.
5. Pressure wash the area
Start by rinsing the area with your pressure washer.
We recommend starting with a 25-degree or 15-degree nozzle. Maintain a safe distance of about 12 inches from the surface.
If you need to clean the entire driveway, you can do so in this step. Read our article on how to clean a driveway with a pressure washer to learn more.
6. Seal the area
A sealant protects your driveway from future stains by adding an extra layer of protection. Apply this to make your next cleaning much more manageable.
Tips and safety considerations
Remember these tips and tricks before starting.
Use the correct nozzle
We know you’re desperate to remove the stain, and you might be tempted to use the highest-pressure nozzle. But, unfortunately, this will damage your surface.
Always begin with the lowest-pressure nozzle and work your way up. We recommend starting with a 25-degree or 15-degree nozzle.
Don’t get too close
We recommend starting with a 12-inch distance from the surface. Then, if necessary, you can gradually get closer.
Pro tip: Make sure you won’t damage the surface by testing your nozzle and distance on a smaller area.
Use driveway-safe cleaning products
Use safe products for concrete, asphalt, and other driveway surfaces. Using harsh chemicals and cleaning agents may damage the surface.
