How to Remove a Grease Stain from a Wool Rug
A grease stain on a wool rug can leave a dark, oily mark, but you can lift it with dish soap and baking soda. Here's a practical guide for fresh and set-in stains, with wool-specific precautions.

How to Remove a Set-In Grease Stain from a Wool Rug
Set-in grease stains are more challenging, but you can still lift them with a combination of dish soap and baking soda. Here's how:
- Apply baking soda to the stain and let it sit for 1-2 hours to absorb as much grease as possible. Vacuum it up.
- Mix a paste of 1 part dish soap and 2 parts baking soda with a little water to make a spreadable consistency.
- Apply the paste to the stain with a soft brush or your fingers, working it in gently.
- Let it sit for 15-20 minutes to allow the paste to break down the grease.
- Blot the area with a damp cloth to remove the paste, then rinse with a cloth dipped in plain water.
- Blot dry and allow the rug to air dry completely. Vacuum once dry to restore the pile.
If the stain persists, you can repeat the process. For very stubborn set-in grease, you may need to use a commercial wool-safe spot cleaner, but always test it on an inconspicuous area first.
What Not to Do
Wool is sensitive to heat, harsh chemicals, and excessive moisture. Avoid the following:
- Do not use hot water – it can set the stain and shrink the wool.
- Do not use bleach or ammonia – these can damage the protein fibers and cause yellowing.
- Do not rub the stain – rubbing can damage the wool fibers and spread the grease.
- Do not use a steam cleaner – the heat and moisture can cause the wool to shrink or distort.
- Do not use a hair dryer – heat can set the stain and damage the rug.
