How to Get Grease Out of Carpet

The slice of pizza is off the floor, but there's still a dark patch where it landed. Or you've found a line of oily footprints leading in from the garage. Both are grease stains, but what came with the grease helps explain what you'll need to remove.

Start by lifting any food or thick grease with a spoon, then blot loose oil with a dry white cloth. Once the excess is out, choose a carpet spot cleaner labelled for grease and suitable for your carpet's fibre. The final rinse matters: you want to remove the oil and the cleaner, so the spot doesn't stay sticky.

Why a greasy food stain can leave two different marks

A drop of cooking oil may leave an oily patch without much colour. Pizza or gravy can leave oil along with coloured food residue. Removing the greasy feel doesn't necessarily remove the red or brown mark, and that remaining colour isn't a reason to keep adding degreaser.

Motor oil tracked in on shoes may bring other grime with it. If you know where it came from, keep the container details. If you've simply found an old dark spot, don't assume it's grease from appearance alone.

Choose your cleaner before wetting the carpet

Look for a product that names both carpet and grease or oil on its label. A spray intended for cooker hoods or garage floors isn't an interchangeable option. For wool, check for approval for wool specifically; our wool and natural-fibre care guide explains why it needs a different approach.

Read how the product is removed, too. If it requires extraction and you only have cloths, choose a method you can finish properly or ask for help. Have white towels, a spoon and any water required for rinsing ready before you begin.

How to remove a fresh grease stain

1. Lift the material sitting on top

Use a spoon to pick up butter, food or thick grease, working from the edges towards the middle. Wipe the spoon between passes. Pressing down or scraping back and forth works the material further into the carpet.

2. Blot the loose oil

Press a dry white cloth onto the patch, lift it and fold to a clean section. Repeat while you're picking up oil. Keep shoes and paws away from the spot so one mark doesn't become a trail through the room.

3. Try the cleaner in a hidden spot

Test it at the label's dilution on a spare offcut or an out-of-the-way area. Let it dry and check the colour and texture. Dye coming onto the cloth, fading or a change in feel means you should stop using that product.

4. Work on the remaining oily patch

Apply the cleaner as its label describes, using the stated amount and contact time. Blot gently and keep moving to clean cloth. Give the first treatment time to work; adding another spray or scrubbing harder can leave more residue or roughen the pile.

5. Remove the cleaner as well as the grease

Complete the product's rinse or extraction step. For a cleaner that allows blot-rinsing, use small amounts of clean water and absorb them with a fresh towel. Pouring water over the patch makes it harder to recover what you've loosened. If using a portable extractor, follow its instructions too, and never use it to collect flammable solvents.

6. Check the spot once it's dry

Blot out the remaining moisture and keep traffic off the area until it dries. Then look at the colour and gently compare its feel with the surrounding carpet. If it still feels oily or sticky, the cleanup may be incomplete even if the dark mark has faded.

These first steps follow the Carpet and Rug Institute's spot-cleaning guidance: remove the spill, test the product, blot gently and remove the cleaning residue.

Can you use washing-up liquid?

It's an understandable choice: it removes grease from plates. The difference is that a plate can go under the tap, while soap in carpet has to be recovered from the fibres. A generous squirt can leave a sticky patch that's difficult to rinse.

Use dishwashing liquid only if your carpet's care instructions give a diluted recipe, and measure that recipe rather than guessing. Dishwasher detergent, laundry detergent and kitchen degreaser are different products and shouldn't be substituted.

Old grease and oil from the garage

For an old mark, start with what you know: where it is, whether it feels oily and what you've already used. A patch beside a dining chair might include food residue; a footprint by the garage door may have a different source. Those are clues for choosing a treatment, not proof of what the stain contains.

Blot fresh motor oil and prevent anyone tracking it farther. For a large spill, a strong chemical smell or oil that has soaked down into the carpet, get advice before wet cleaning. Don't use petrol, brake cleaner or automotive solvents on the carpet.

Why the same spot can keep returning

If the patch gradually darkens again as people walk over it, leftover grease or detergent may be collecting new dirt. If it reappears while drying, material from deeper in the carpet may be moving back towards the surface. A cleaner needs to investigate before deciding which explanation fits.

That is why another round of the same spray may not solve it. Make a note of when the mark returned and whether it feels sticky. Both details are useful when arranging treatment.
