How to Remove Grease & Oil Stains from Carpet, Tile & Concrete

Grease and oil stains are among the most common and stubborn stains homeowners face — from cooking oil in the kitchen to motor oil tracked in from the garage. The key to grease removal is understanding that oil and water don't mix: you need either an absorbent (to pull oil out), a degreaser (to break oil down), or a solvent (to dissolve oil) — not just water and blotting.

Removing Fresh Grease from Carpet

For fresh cooking grease, butter, or oil spills, fast action gives the best results:

1. Blot excess immediately: Use a clean white cloth or paper towel to blot (never rub) the excess grease. Press firmly to absorb as much as possible.
2. Apply absorbent powder: Cover the stain generously with cornstarch, baking soda, or talcum powder. These dry powders absorb oil from the carpet fibers.
3. Let sit 15-30 minutes: Give the powder time to absorb the grease. For large spills, leave it longer.
4. Vacuum thoroughly: Vacuum up the powder, which should now be clumped with absorbed grease.
5. Apply dish soap solution: Mix 1 teaspoon of clear dish soap (no bleach, no moisturizers) with 2 cups of warm water. Dish soap is specifically designed to cut grease. Apply to the stain and blot from outside in.
6. Rinse and blot dry: Apply clean warm water and blot thoroughly to remove all soap residue. Place a weighted towel over the area to absorb deep moisture.

Removing Set-In Grease from Carpet

Old grease stains that have been in the carpet for days or weeks are harder but often still removable:

1. Apply dry-cleaning solvent: Apply a small amount of dry-cleaning solvent or Goo Gone to a clean white cloth (test on a hidden area first). Blot the stain to break down the old oil.
2. Let it penetrate: Allow 5-10 minutes for the solvent to break down the grease.
3. Apply dish soap: Follow with dish soap solution and blot, as the soap cuts the now-loosened grease.
4. Rinse thoroughly: Apply clean water and blot. Repeat the rinse cycle 3-4 times to remove all solvent and soap residue.
5. Professional extraction: For deep, set-in grease, professional carpet extraction with commercial degreasers is the most effective option. Truck-mounted equipment flushes and extracts in a single pass.

Removing Motor Oil from Carpet and Concrete

Motor oil is thicker and more heavily pigmented than cooking grease, making it harder to remove:

• On carpet: Follow the same process as cooking grease — absorb with powder, treat with dish soap or solvent, rinse thoroughly. Motor oil's dark pigment may leave a visible stain even after oil removal. Professional extraction may be needed.
• On concrete/garage floors: Absorb excess with kitty litter or sawdust. Apply a commercial degreaser or TSP (trisodium phosphate) solution, scrub with a stiff nylon brush, and rinse with a pressure washer. For deeply penetrated oil, multiple treatments may be needed.

Removing Grease from Tile and Grout

Kitchen grease accumulates on tile backsplashes, floors, and especially in grout lines:

1. Apply degreaser: Use a commercial kitchen degreaser or a dish soap solution. Spray or apply to the greasy tile surface.
2. Wipe tile surface: For smooth tile, wiping with a degreaser and microfiber cloth is usually sufficient.
3. Scrub grout lines: Grease accumulates in grout pores. Make a paste of baking soda and water, apply to grout, and scrub with a nylon grout brush. Let sit 10-15 minutes, then rinse.
4. Professional cleaning for stubborn grease: For deeply embedded grease in grout, professional high-pressure tile and grout cleaning uses truck-mounted equipment to blast grease from grout pores. Learn more in our guide to cleaning grout lines effectively.

What NOT to Do

• Don't use just water. Oil and water don't mix — water alone will spread the grease, not remove it. Always use a degreaser (dish soap) or solvent.
• Don't rub or scrub. Rubbing pushes grease deeper into fibers and spreads the stain. Always blot.
• Don't skip the absorbent step. For fresh spills, dry powder absorbs grease that blotting alone can't reach.
• Don't use bleach. Bleach doesn't dissolve grease and can damage carpet fibers and color. Stick with degreasers and solvents.
• Don't leave soap residue. Dish soap left in carpet attracts soil rapidly. Always rinse thoroughly with clean water.

When to Call a Professional

Grease and oil are among the stains that benefit most from professional truck-mounted extraction. The high-pressure injection and powerful vacuum recovery flush grease from deep within carpet fibers and padding — something surface cleaning can't achieve. If your grease stain is large, set-in, or has spread to the padding, call HydroLux Floor Care at (813) 607-1182. Serving Wesley Chapel, New Tampa, Lutz, Trinity, Odessa, and Citrus Park.
