How to Get Grease Out of Carpet — Oil, Butter, Gravy and More

Gravy off the edge of a plate. A slice of pizza that landed cheese-side down. Butter, salad dressing, cooking oil from the kitchen, or the black bike-chain grease someone rolled across the living room. Grease stains are some of the most common calls we get between Thanksgiving and New Year's — and some of the most misunderstood. Grease does not act like other stains, so the usual "water and scrub" approach makes it worse.

Here is what our crews tell people on the phone: how to get grease and oil out of carpet step by step, what to use for each kind, and why some spots come back dark a week later.

Why grease is different from other carpet stains

Most spills — coffee, juice, soda — are water-based. Water cleans them. Grease is oil, and oil and water don't mix. If you pour water on a grease spot, the water just moves the oil around and pushes it deeper.

Three more things make grease tricky:

• It spreads. Oil wicks along carpet fibers, so a small drop can become a bigger, fuzzy-edged spot over a few hours.
• It's sticky. Even after the color is gone, a thin oily film can stay on the fibers. That film grabs dirt from shoes, and the clean spot turns gray or black within days.
• It ages. Old oil oxidizes and can leave a yellow or brown shadow that is much harder to remove.

The good news: fresh grease on most synthetic carpet comes out very well if you go in the right order — absorb first, then cut the oil, then rinse.

How to get grease out of carpet: step by step

1. Lift off everything you can

Scrape up any solid food or thick grease with a spoon or a dull butter knife. Work from the outside edge toward the center so you don't make the spot bigger. Then blot — press, don't rub — with a dry paper towel or white cloth to pick up as much liquid oil as possible.

2. Pull the oil out with baking soda or cornstarch

Cover the spot with a thick layer of baking soda or cornstarch. Both are fine powders that soak up oil. Press lightly with your fingers so the powder touches the fibers, then leave it for at least 15 to 30 minutes. For a big spill, leave it longer. When the powder looks clumpy or darker, vacuum it up. If the spot still looks oily, repeat once.

3. Cut the grease with dish soap and lukewarm water

Mix about a quarter teaspoon of clear grease-cutting dish soap into one cup of lukewarm water. Dampen a clean white cloth — don't pour — and blot the spot from the outside in. Dish soap is made to break up kitchen grease. Use only a little — more soap just means more residue.

4. For a stubborn oily shadow, try a dry solvent

If a faint oily mark is still there, a solvent can dissolve what soap couldn't. Put a small amount of rubbing alcohol, or a store-bought solvent-based carpet spot remover, on a white cloth — never directly on the carpet — and dab the spot. Test it first in a hidden place, like inside a closet. Solvents can damage the latex glue in carpet backing if you soak it, so use very little. Skip this step on wool, silk and viscose.

5. Rinse, then dry fast

Blot the area with a cloth dampened in plain water to remove the soap. This step is the one most people skip — and it's the reason the spot comes back dark. Then put a stack of dry white towels on the spot with something heavy on top, like a few books. Change the towels until they come up dry, and run a fan over the area.

What to use for each kind of grease

"Grease" means many different things in a home. Here's what we use as a first step for the common ones:

Candle wax and crayon are oily too, but they need a different method. See our guide to removing wax, gum and slime from carpet.

Mistakes that make grease stains worse

• Pouring water on it. Water floats the oil deeper into the backing and pad, where it slowly wicks back up.
• Rubbing hard. Rubbing spreads the oil and frays the fiber tips, so the area looks fuzzy and different even when it's clean.
• Too much soap. Leftover soap is sticky, just like grease. It's the most common reason a spot "comes back."
• WD-40 or other oily sprays. They may loosen a stain, but you've just added more oil to remove.
• Bleach or mixing products. Bleach removes carpet color for good. Never mix cleaners — rinse between products.
• The iron and paper bag trick on grease. It can work for wax, but on liquid grease the heat often pushes oil deeper and can melt synthetic fibers. We don't recommend it.

Why the spot turns dark again a week later

A gray shadow shows up where you cleaned. This is called resoiling, and it almost always has one of two causes:

• Residue. A little grease or soap stayed on the fibers and is now collecting dirt from shoes.
• Wicking. Oil that reached the backing is slowly moving back up to the surface as the carpet dries.

For residue, blot again with plain water and dry well. For wicking, surface cleaning won't reach the source. A professional rinse with hot water extraction flushes the fibers and pulls the oily water back out at the same time, so nothing is left to wick.

Grease on rugs, couches and kitchen tile

Wool and Oriental rugs

Absorb with cornstarch, then blot with a very mild soap solution and rinse. Skip solvents and strong degreasers, which can strip wool's natural oils or make dyes run. Viscose and "art silk" rugs are much more delicate: blot and absorb only, then call a pro. Our area and Oriental rug cleaning is done in your home or at our facility, with rug pickup and delivery.

Sofas and chairs

Before you touch a grease spot on a couch, check the cleaning code on the tag. Many sofas are coded "S" (solvent only), which means water and soap can leave a ring. Our guide to upholstery cleaning codes W, S, WS and X explains what each one allows. For headrest and armrest oil — the dark spots from hair and skin — our upholstery cleaning removes them without soaking the cushions.

Kitchen floors

Cooking grease lands on the floor, settles into grout lines and turns them dark — then gets tracked into the next room. Our guide on how to clean grout covers safe DIY steps, and our tile and grout cleaning deep cleans what scrubbing can't reach.

Hosting Thanksgiving or the holidays? A quick plan

• Keep a box of baking soda, clear dish soap and a stack of white towels near the dining room.
• Put a washable runner or mat under the serving table and in the path from kitchen to dining room.
• Deal with spills the same night. Fresh grease is easy; grease that sat through a weekend of foot traffic is not.

When to call a professional

DIY works for most small, fresh food spills. Call a pro when:

• The spot is still visible after two careful tries.
• It's motor oil, bike grease or another black petroleum stain.
• A dark ring keeps coming back after the carpet dries.
• The rug is wool, silk, viscose or an heirloom.
• There's a grease trail across a hallway, a dining room or a restaurant floor.

Our IICRC-certified technicians identify the fiber first, pre-treat with a degreaser matched to it, then rinse and extract during our carpet cleaning. We use organic, kid- and pet-safe products, and carpets are usually dry within a few hours. Restaurants, offices and lobbies with grease tracked in from the street can book commercial carpet cleaning after hours, and we provide certificates of insurance (COI) for buildings that need them.

Our crews cover every borough — from brownstones in Park Slope to homes across Nassau County and Suffolk, including the Hamptons.
