Carpeting is wickedly expensive to replace, so it’s important to know how to clean carpet stains the right way. A stained carpet can make your home look dirty even when everything else is clean.
How to Clean Carpet Stains
General carpet stains
Fresh carpet stains from food, beverages, pets, grease, and other substances will usually come up warm water and a small amount of liquid dish detergent. (I use Dawn Original. In the UK, try Sunlight Dishwashing Liquid.) If this doesn’t completely remove the stain, immediately move onto one of the methods below, so the mess doesn’t have a chance to set.
Foods, feces, mud and latex paint
Clean any remaining stain with a solution of 1 part white vinegar to 3 parts hot water. Spray the area and blot the stain away with a clean, white cloth. Rotate the fabric as you work so you aren’t spreading the mess.
Blood, chocolate, wine, ketchup, and coffee
Blot up as much of the spill as possible, then dab with club soda and a clean cloth. For stubborn stains, mix 1 tablespoon of clear household ammonia in 1/2 cup of water. Spray on stain, but don’t soak the carpet padding beneath. Dab it with a clean cloth, rinsing and changing your fabric often as the stain transfers to it.
Once the stain is gone, clean the area with fresh water to remove the remaining ammonia then blot dry.
Greasy carpet stains
Blot the area until it’s dry to touch. Sprinkle with 1/4 cup of baking soda and rub this into the stain. In a small bowl, combine 1 cup hot white distilled vinegar, 1/2 cup hydrogen peroxide (3%), and 1/2 teaspoon of liquid dish detergent. Have a stack of clean, white cloths handy.
Slowly pour the soapy vinegar over the stain. The bubbling chemical reaction between the vinegar and baking soda will pull the stain out of the carpet fibers. Once you’ve finished pouring, blot the stain away. Let dry then vacuum.
Other common carpet stain treatments
Old Carpet Stains
1. First, see if warm water with a few drops of liquid dish detergent can lift the stain out. Use a clean, white cloth and change it frequently as you work.
2. Next, spray the area with 1 part white vinegar and 3 parts warm water, then spread a towel over it and go over the carpet stain with an iron using the steam setting. This will transfer the mess to your cloth, so you’ll need to change it out often as you work. Let dry, and vacuum to restore the carpet’s fluff. (You can see how well this worked on my carpets.)
3. Stain still there? Use 1 part clear household ammonia and 3 parts hot water. Spray on, scrub into the rug with a stiff-bristled brush, and use the ironing-transfer process described above. Be sure to spray with fresh water and blot with a clean towel to remove the ammonia then let it dry and vacuum thoroughly.
