Grease stains on carpet can quickly become unsightly, whether it’s a cooking mishap in the kitchen or oil from machinery in a home workshop. Learning how to remove grease stains from carpet effectively can save time, money and stress—especially when you’re juggling a busy schedule.

For a complete walkthrough on maintaining spotless flooring, learn how to clean carpet full edition with our in-depth guide.

Understanding Grease vs. Oil Stains

Though often used interchangeably, ‘grease’ and ‘oil’ stains differ slightly. Grease tends to be thicker—think butter, margarine or frying oil—whereas oil spills (such as engine oil or salad dressing) can be more fluid.

Both penetrate carpet fibres, attracting dirt and grime over time. Synthetic carpets (nylon, polyester) usually resist grease better than natural fibres (wool, cotton), but all carpets can benefit from prompt treatment.

Why Prompt Action Is Critical

Grease is hydrophobic, meaning it repels water and clings strongly to fibres. The longer it sits, the deeper it bonds with the carpet backing and underlay.

• Immediate Blotting: Absorbs excess before it spreads.
• Avoid Rubbing: Prevents grease from embedding further.
• Layered Treatment: Fresh stains need only one pass; older ones often need repeat attempts.

Essential Tools and Materials

Before you begin, gather these items to tackle the stain swiftly:

• Clean white cloths or paper towels
• Cornstarch or baking soda
• Vacuum cleaner (with hose attachment)
• Dishwashing liquid (dye-free, mild)
• Warm water and spray bottle
• Soft-bristled brush (e.g., toothbrush)
• Commercial carpet degreaser (optional)
• Protective gloves

Step-by-Step Guide to Remove Grease Stains from Carpet

1. Blot Up Excess Grease

Gently press a clean cloth onto the stain to absorb as much grease as possible. Work from the edges towards the centre to avoid spreading.

2. Apply an Absorbent Powder

Sprinkle a generous layer of cornstarch or baking soda over the stain. These dry powders draw oil out of the fibres.

Leave for at least 15–30 minutes—or overnight for set-in marks.

3. Vacuum the Powder

Use your vacuum’s hose attachment to remove the powder. You should see a noticeable lightening of the stain.

4. Mix Dishwashing Liquid Solution

Combine one teaspoon of mild dishwashing liquid with one mug of warm water. Pour the mixture into a spray bottle.

5. Pre-Treat the Stain

Lightly mist the stained area—avoid soaking. Allow 5 minutes for the detergent to break down remaining grease.

6. Blot and Brush Gently

Blot with a new white cloth to lift the dissolved grease. For stubborn edges, use a soft-bristled brush to agitate fibres gently.

7. Rinse Thoroughly

Spray plain warm water to rinse out detergent residue. Blot with a dry cloth until the carpet feels only slightly damp.

8. Repeat or Use a Commercial Degreaser

If traces remain, repeat steps 2–7. For very tough stains—such as automotive oil—apply a specialist carpet degreaser following the manufacturer’s instructions and patch-test first.

9. Final Dry and Groom

Once clean, allow the area to air-dry fully. Use a clean brush to lift the carpet pile, restoring its texture.

Alternative Home Remedies

If you’re keen on natural methods, consider:

• White Vinegar: Mix one part vinegar with two parts water. Test on a hidden patch first to avoid discolouration.
• Club Soda: Blot the stain with club soda; its carbonation can lift fresh grease.
• WD-40: Spray lightly, blot immediately, then follow with dish soap. Always test a discreet area first.

FAQs

How quickly should I treat a grease stain?

Tackle it as soon as possible—ideally within minutes. Fresh grease is far easier to remove than set-in oil.

Can I use white vinegar on coloured carpets?

When diluted (one part vinegar to two parts water), it’s generally safe. Always patch-test first to ensure no discolouration.

Is it better to use cornstarch or baking soda?

Both work well. Cornstarch is slightly finer and may feel gentler on delicate fibres.

Will dishwashing liquid damage my carpet?

Mild, dye-free detergents are safe when diluted correctly. Rinse thoroughly to avoid sticky residue.

My stain is old—what next?

Older grease stains often require professional intervention. If home methods fail after two attempts, contact Glohus for expert cleaning.
