Whether it's an old or new stain, grease can be intimidating to remove from carpet. However, with a few key products and some patience, you can get the grease up. Some stains may need all of the methods, while others may only require the first.
Scrape up any excess grease with a butter knife.
Sprinkle baking soda on the grease stain. Allow it to sit for about 15 minutes to soak up some of the grease.
Vacuum the baking soda from the spot. Be careful not to rub at the stain with your vacuum.
Blot at the stain with dry-cleaning solvent using a clean, white cloth until the solvent is absorbed.
Place 1 tbsp. of grease-cutting dish washing detergent in 2 cups of warm water along with 1 tbsp. of white vinegar.
Dip a clean, white cloth into the solution and place on the stain.
Blot at the spot until the solution is absorbed. Keep switching to clean areas on the cloth or get a new cloth when this one is completely dirty.
Use a sponge and cold water to flush the area of the detergent solution. Blot dry.
