How to Remove Grease from Carpet

Grease stains on carpet — from food, cooking, machinery, or hair products — are among the most stubborn because grease repels water and bonds tightly to carpet fibers. The solution is to use absorbents to draw the grease out, then grease-cutting agents to break it down. Here's the complete method.

What You'll Need

• Nutricost Baking Soda (2 LBS) – absorbs grease from carpet fibers
• Dish soap (clear, grease-cutting formula — Dawn or similar)
• Rubbing alcohol
• FOLEX Instant Carpet Spot Remover (32 oz)
• HOMEXCEL Microfiber Cleaning Cloths (Pack of 12)
• Empty Spray Bottles (16oz, 2-Pack)
• Warm water
• A dull knife or spoon (for solid grease)

Step-by-Step: Removing Grease from Carpet

Step 1: Remove Excess Grease

If the grease is solid or semi-solid (like butter, lard, or thick cooking grease), use a dull knife or spoon to carefully scrape away as much as possible from the carpet surface. Work from the outside in. For liquid grease, blot — don't rub — with a clean microfiber cloth to absorb as much as possible before treating.

Step 2: Apply Baking Soda Generously

Cover the entire grease stain with a thick, generous layer of baking soda. Baking soda is highly absorbent and will draw the grease out of the carpet fibers. Press it gently into the stain. Let it sit for at least 20–30 minutes — for heavy grease, leave it for several hours. You'll see the baking soda clumping as it absorbs the grease. Vacuum thoroughly.

Step 3: Apply Dish Soap Solution

Mix 1 teaspoon of grease-cutting dish soap with 1 cup of warm water in a spray bottle. Apply to the stain and work it into the fibers gently with your fingers or a soft brush. Dish soap contains surfactants specifically designed to surround and lift grease molecules — it's your most powerful tool for this type of stain.

Step 4: Blot Firmly

Using a clean microfiber cloth, blot the area firmly from the outside in. The dish soap will have emulsified the grease, making it easier to lift. Continue blotting with fresh sections of cloth until no more grease transfers. Do not rub — rubbing spreads the grease and pushes it deeper.

Step 5: Rinse Thoroughly

Spray clean warm water over the area to rinse out the dish soap. Blot again with a dry cloth. Repeat the rinse 2–3 times — leftover soap residue attracts dirt and will make the carpet re-soil faster.

Step 6: Apply Rubbing Alcohol for Stubborn Grease

If a greasy residue or sheen remains, dampen a clean cloth with rubbing alcohol and dab the area. Rubbing alcohol is a solvent that dissolves grease effectively. Blot from the outside in and use fresh sections of cloth as they pick up grease.

Step 7: Apply FOLEX

For any remaining stain or discoloration, apply FOLEX Instant Carpet Spot Remover directly to the area. Work it in gently and blot with a clean cloth. FOLEX is highly effective on grease and oil-based stains.

Step 8: Final Baking Soda Treatment

Once the area is mostly clean, sprinkle baking soda over the damp carpet and let it sit until fully dry. This absorbs any remaining grease residue and deodorizes the area. Vacuum thoroughly once dry.

Common Grease Stain Sources and Tips

• Food grease (pizza, fried food, chips): Baking soda + dish soap method works excellently.
• Butter or margarine: Let it harden in the fridge if possible, scrape, then treat as above.
• Hair products (pomade, hair oil): Rubbing alcohol as a pre-treatment, then dish soap.
• Mechanical grease / WD-40: May require multiple treatments; dish soap is most effective.
• Sunscreen: Treat as grease — baking soda absorption followed by dish soap.

What Not to Do

• Don't use hot water — it can spread the grease and set the stain.
• Don't rub — always blot to avoid spreading and fiber damage.
• Don't skip the baking soda step — it's essential for absorbing grease before liquid treatment.
• Don't leave soap residue — rinse thoroughly to prevent re-soiling.

Final Thoughts

Grease stains require a two-phase approach: absorb first with baking soda, then cut the grease with dish soap and rubbing alcohol. With patience and thorough rinsing, even heavy grease stains can be fully removed from carpet without leaving a trace.
