How to Remove Oil From Cement Garage Floor

Oil stains on cement garage floors can ruin the garage's aesthetics. Aside from being unsightly, oil stains can create slippery surfaces and pose safety hazards to anyone entering the garage, especially if it is in a commercial setting. There are various reasons why your garage floor may have oil stains, from a minor leak from your vehicle to a large spill from a piece of equipment. Regardless of the cause, several methods can effectively remove oil stains from cement garage floors.

It's important to note that some of these methods are more suitable for specific types of oil stains. For instance, some methods work better on fresh stains, while others are more effective on older stains. It's essential to determine the age of the stain and choose the right method for the job.

Materials Required

Before starting the cleaning process, gather the following materials:

Oil-absorbing pads or kitty litter
Broom or shop vac
Degreaser or dish soap
Baking soda or sawdust
Pressure washer (optional)
Muriatic acid (optional)

Step-by-Step Instructions

Soak Up Fresh Spills: If the oil spill is still fresh, immediately start absorbing as much oil as possible using absorbent materials like oil-absorbing pads or kitty litter. Spread the material over the stain and allow it to soak up the oil. Once it's fully saturated, sweep or vacuum it up.
Apply Degreaser or Dish Soap: Mix a degreaser or dish soap with water according to the manufacturer's instructions. Apply the solution onto the stained area and let it sit for some time. The degreaser or dish soap will help break down the oil and lift it from the pores of the concrete.
Sprinkle Baking Soda or Sawdust: After applying the degreaser, cover the stained area with baking soda or sawdust. These substances will absorb the remaining oil and further lift it from the concrete.
Scrub the Area: Using a brush or sponge, scrub the baking soda or sawdust into the stain. Circular motions are recommended for this process. Rinse the area with clean water and inspect if the stain has been removed. Repeat steps 2 and 3 if necessary.
Use a Pressure Washer (Optional): For more stubborn stains, a pressure washer can be used to blast away the oil and degreaser residue. Ensure you adjust the pressure setting to avoid damaging the concrete. Use a wide-angle spray nozzle to prevent gouging the surface.
Apply Muriatic Acid (Optional): Muriatic acid is a powerful acid that can remove tough oil stains. It is important to use this substance with caution and follow the manufacturer's instructions carefully. Muriatic acid may damage the concrete if not properly diluted and used. Ensure adequate ventilation and wear protective gear while using muriatic acid.

Tips for Preventing Future Oil Stains

Regularly check your vehicles for leaks and fix them promptly.
Place oil drip pans under vehicles parked in the garage.
Use absorbent mats or rugs in areas where oil spills are likely to occur.
Consider applying a concrete sealant to protect the floor from stains and spills.
