How to Get Coffee Stains Out of Carpet and Mugs

Americans drink over 400 million cups of coffee per day, and a fair number of those cups end up tipped, splashed, or dripped onto carpet, clothing, and countertops. Coffee stains because of tannins — the same compounds that make tea and wine stain. These tannins bond with fabric fibers and become harder to remove the longer they sit.

The good news is that coffee is a water-based stain, which means it responds well to common cleaning solutions. This guide covers how to remove coffee from carpet, clothing, mugs, and countertops — both fresh and dried.

Removing Fresh Coffee Stains from Carpet

Speed is everything with coffee on carpet. The tannins begin bonding with carpet fibers within minutes.

1. Blot immediately. Use a clean white cloth or paper towels to absorb as much coffee as possible. Press firmly and work from the outside edges inward to contain the stain. Do not rub.
2. Flush with cold water. Pour a small amount of cold water onto the stain to dilute the remaining coffee. Blot again to absorb the diluted liquid.
3. Apply cleaning solution. Mix one tablespoon of liquid dish soap, one tablespoon of white vinegar, and two cups of cold water. Apply to the stain with a clean cloth, working from the edges inward.
4. Blot and repeat. Blot with a dry cloth to absorb the solution and lifted coffee. Reapply the cleaning solution and blot again until the stain is gone.
5. Rinse with cold water. Dampen a clean cloth with plain cold water and blot the area to remove soap residue.
6. Dry the area. Place a stack of paper towels over the wet spot and weigh them down with a heavy book. Leave for several hours to absorb remaining moisture and prevent mold.

Removing Dried Coffee Stains from Carpet

Dried coffee stains require rehydration before treatment.

1. Dampen the stain. Apply cold water to the dried stain and let it sit for 5 minutes to loosen the tannins.
2. Apply the dish soap and vinegar solution described above. Let it sit for 10 minutes.
3. Blot and repeat until the stain lightens.
4. For stubborn stains, apply a paste of baking soda and water. Let it sit for 30 minutes, then vacuum.
5. If the stain persists on light carpet, dab 3% hydrogen peroxide onto the remaining stain. Let it sit for one hour, then blot with a damp cloth. Test in a hidden area first — peroxide can lighten carpet color.

Coffee with Cream or Milk

Coffee with dairy additives is harder to remove because you are dealing with two stain types: tannin (coffee) and protein (milk). Use an enzyme-based cleaner like Folex or Biokleen Bac-Out after the initial dish soap treatment. Enzyme cleaners break down the protein component that regular soap leaves behind.

Removing Coffee Stains from Clothing

Fresh Coffee on Clothes

1. Run cold water through the back of the stain (opposite the stained side) to push the coffee out of the fabric.
2. Apply liquid laundry detergent or dish soap directly to the stain.
3. Rub the fabric gently against itself to work the soap into the stain.
4. Let it sit for 5 minutes, then rinse with cold water.
5. If the stain remains, soak the garment in a mixture of one quart cold water and one tablespoon white vinegar for 15 minutes.
6. Wash in the washing machine on the cold setting.

Do not put the garment in the dryer until the stain is completely gone. Heat from the dryer sets coffee stains permanently.

Dried Coffee on Clothes

Soak the garment in a solution of warm water and oxygen-based bleach (like OxiClean) for 1 to 4 hours. Then wash on the warmest setting the fabric allows. Check the stain before drying — repeat soaking if necessary.

Removing Coffee Stains from Mugs and Cups

Those brown rings inside your favorite mug are tannin buildup from repeated use. They are easy to remove:

Method 1: Baking Soda Paste

1. Sprinkle baking soda into the stained mug.
2. Add just enough water to make a paste.
3. Scrub with a sponge or cloth for 30 seconds.
4. Rinse and repeat if needed.

Method 2: Vinegar Soak

1. Fill the mug with equal parts white vinegar and warm water.
2. Let it soak for 15 to 30 minutes.
3. Scrub with a sponge and rinse.

Method 3: Denture Cleaning Tablets

Drop a denture cleaning tablet into the mug, fill with warm water, and let it fizz for 30 minutes. The effervescent action lifts stains from ceramic and stainless steel travel mugs. Rinse thoroughly.

Removing Coffee Stains from Countertops

• Laminate and quartz: Wipe with a cloth dampened with baking soda paste or a multi-surface cleaner. Coffee stains rarely penetrate these non-porous surfaces.
• Granite and marble: Make a paste of baking soda and water, apply it to the stain, cover with plastic wrap, and let it sit overnight. The paste draws the stain out of the porous stone. Do not use vinegar on natural stone.
• Butcher block: Sprinkle salt and baking soda on the stain, scrub with half a lemon, and rinse. The acid in the lemon helps lift the tannins from wood.

Prevention Tips for Coffee Lovers

• Use a travel mug with a secure lid to prevent spills on carpet and furniture.
• Rinse coffee mugs immediately after use — tannin buildup happens when coffee dries in the cup.
• Keep stain remover accessible. A small spray bottle of the dish soap and vinegar solution stored under the sink means you can treat spills within seconds.
• Use coasters and placemats to protect wood and stone surfaces from coffee ring stains.
• Treat carpet with a stain-resistant spray like Scotchgard in high-traffic areas if you frequently drink coffee on the couch.

Do Not Let Coffee Stains Win

Coffee stains look bad but respond well to simple household products — dish soap, vinegar, and baking soda handle the vast majority of coffee spills. The key is treating the stain quickly and avoiding hot water, which sets the tannins. For dried or large stains on carpet, enzyme cleaners and hydrogen peroxide provide the extra power you need.
