How to Remove Oil Stains from Concrete

How to Remove Oil Stains from Concrete

Trying to remove oil stains off concrete is not always an easy task. Pressure washing oil stains is a common removal technique, however, it is not the most environmentally friendly option. It is a waste of water, and it also puts the surrounding groundwater at risk when the grease, grime, and soap are absorbed into the ground. Instead of allowing the remnants of oil stains and cleaner runoff to potentially damage the environment, use EXIMO® Waterless Concrete Cleaner that uses a bioremediation process to consume and break down those pollutants.

We developed EXIMO Waterless Concrete Cleaner to help you completely remove oil stains from concrete. EXIMO works because of the microorganisms that break down the hydrocarbon chain of oil stains that lurk deep in the pores of the concrete. In simpler terms, EXIMO consumes the oil and turns it into harmless water and CO2.

By using EXIMO, you can get remove oil stains easily by following these steps:

Gather Supplies

  • If using the dry method, use EXIMO and an application broom.
  • If using the wet method, use EXIMO, have access to water, and a 2-gallon sprayer container

Cone Off the Area

  • Safety is always important, make sure to be using the right safety equipment and tools.

Apply Product

  • There are two methods to using EXIMO, either dry or wet.


Using the EXIMO® Dry Method of Removal

If you prefer to not use water to remove your oil stains, start the dry removal process by first ensuring the area is dry and clean of all debris. From there:

  • Apply EXIMO® directly to the oil spot with the provided scoop.
    • ¼ cup will cover up to 55 sq. ft.
  • Sweep the product forward, keeping the broom in contact with the surface, and then back across the oil spot. Then, sweep across the initial line until the powder is fully dispersed.
    • Applying the correct amount of the EXIMO® product should leave no excess. If excess remains, sweep until the product is completely dispersed.
  • Leave EXIMO® on your concrete surface for 4-6 weeks, during which time the oil will be absorbed. You can re-apply EXIMO® weekly to prevent future staining.


Using the EXIMO® Wet Method of Removal

If you decide to use the EXIMO® wet method, it is still important that the area is dry and free of trash and debris prior to starting. Once that step is complete, you can:

  • Add water to a 2-gallon sprayer container. Add 1 cup of EXIMO® to 1 gallon of water using the scoop provided with your product. Mix thoroughly. Then, attach the pump handle to the pump to pressurize the sprayer tank.
  • Apply the product with a forward line motion, keeping the sprayer 12 inches from the ground. This process creates wide, long lines of EXIMO®. Be careful not to puddle or apply too much of the EXIMO® product while spraying. Keep using a back and forth motion, using even strokes.
  • Leave EXIMO® on your concrete surface for 4-6 weeks. Oil stains will be absorbed over this time. As with the dry method, you can re-apply EXIMO® weekly to prevent future staining.
