Get the area ready to remove grease
Start by opening the garage door for fresh air. Put on gloves and eye protection. Concrete is like a sponge, so the quicker you act, the better your results.
If the spill is fresh, cover it with clay kitty litter or oil dry. Step on it to press it into the stain. Let it sit for at least 30 minutes, then sweep it up. For old stains, gently scrape any thick residue with a plastic scraper before you wash.
Supplies you’ll need to clean garage concrete
- Clay kitty litter or oil-absorbent granules
- Dish soap or a dedicated concrete degreaser
- Warm to hot water (not boiling on sealed floors)
- Stiff nylon brush or deck brush
- Enzymatic cleaner (optional for deep, old stains)
- TSP substitute or oxygen cleaner (optional; follow safety labels)
- Clean rags or paper towels
- Baking soda for odor and light residue
- Protective gloves and eye protection

Step-by-step method for tough stains
- Dry lift the grease: For new spills, absorb first as described above. For older stains, move right to soap.
- Pre-treat with soap: Add a puddle of dish soap directly on the spot. Dish soap cuts oil well. Add a splash of warm water.
- Scrub: Use a stiff nylon brush. Work the soap into the concrete in small circles. Keep scrubbing for 2 to 5 minutes.
- Let it dwell: Give the soapy area 10 to 15 minutes to work. Don’t let it dry. Add a little water if needed.
- Rinse and check: Rinse with warm water and blot with rags. If the stain remains, repeat the scrub cycle. Most stains fade after two to three rounds.
This simple loop—soap, scrub, dwell, rinse—often solves the problem. If the stain is still visible, move to a stronger cleaner made for concrete.
Safe cleaners for concrete grease
For old, set-in marks, try a concrete degreaser. Citrus-based or solvent-free products are easier on your lungs and still powerful. Follow the label and test a small spot first. Enzymatic cleaners are also helpful. They “eat” oil over time, which is great for older stains that keep bleeding back.
If you choose a TSP substitute, wear gloves and eye protection, and never mix it with other chemicals. Rinse well and keep runoff out of storm drains. When using stronger products, a second or third application is normal. Concrete holds onto oil like a memory, so steady, repeated cleaning works best.

If the stain won’t quit, try a poultice
A poultice pulls oil up from the pores of concrete. It’s like putting a sponge right where you need it.
- Make the mix: Combine a powdered absorbent (baking soda or fine kitty litter) with a concrete-safe degreaser to form a thick paste.
- Spread and cover: Spread the paste over the stain at least a quarter inch thick. Cover with plastic wrap and tape the edges to slow drying.
- Wait: Let it sit 12 to 24 hours so it can draw oil out of the concrete.
- Remove: Scrape off the paste, dispose of it safely, then rinse and scrub the spot with soap and water.
Repeat the poultice if the stain lightens but does not fully leave. Deep stains may need two rounds.
When to try pressure washing
Pressure washing helps when dirt and grime lock grease into the surface. Keep the nozzle 12 to 18 inches from the slab and start with a wide fan tip. Too much pressure can etch concrete, which gives future stains more places to hide. Pre-treat with soap or degreaser first, then rinse with the washer. Work in sections, and don’t drive water into garage walls or under doors.

Once the stain is gone, think about prevention. A small change now can save you big cleanups later.
- Use drip pans under cars and mowers.
- Place a garage floor mat where you park.
- Wipe small spills right away with kitty litter or baking soda.
- Seal the concrete every one to three years, depending on traffic. A sealer makes future cleanups faster.
- Do a quick monthly scrub in high-traffic spots to stop buildup.
