How often do you spill coffee or tea on your favorite cup? If you’re like me, you probably clean them off immediately after each incident. But did you ever wonder why they don’t come out easily?
There are a number of ways to get rid of coffee stains on cups. Some involve soaking the stain in water, while other methods include rubbing alcohol, dish soap, or even vinegar. But none of these methods really work well, especially if you want to remove the stain permanently.
Here’s a quick guide to removing coffee stains from cups.

Why coffee gets dishes dirty
Coffee can leave stains on dishes because it contains a number of compounds that can leave behind pigments when they come into contact with certain materials. These compounds include tannins, which are a type of plant pigment found in coffee beans and other plant-based foods and beverages. Tannins are responsible for the astringent taste of coffee and can also cause staining when they come into contact with certain materials, such as ceramic and glass.
In addition to tannins, coffee also contains other pigments, such as chlorogenic acids and melanoidins, which can also contribute to staining. The pH of coffee is also slightly acidic, which can cause it to react with certain materials and cause staining.
The intensity of the stain that coffee leaves on dishes can depend on a number of factors, such as the strength of the coffee, the type of cup or dish it is served in, and how long the coffee is allowed to sit on the surface before it is cleaned.
What you’ll need
To remove coffee stains from cups, you will need the following supplies:
- Warm water
- Dish soap
- Soft scrub brush or sponge
- White vinegar (optional)
- Commercial stain remover (optional)
- Bleach (optional)
You may also need a sink or basin to soak the cup in, depending on the method you choose to use. Be sure to have clean towels or paper towels on hand to dry the cup after it has been cleaned.
Remember to use caution when handling bleach and to follow the instructions on the package for best results. It is important to rinse the cup thoroughly with clean water after using bleach to remove any residue.
The removal process
To remove coffee stains from cups, follow these steps:
- Rinse the cup with warm water to remove any loose debris.
- Mix a few drops of dish soap into a basin of warm water. Submerge the cup in the soapy water and let it soak for at least 30 minutes to loosen the stain.
- After the cup has soaked, use a soft scrub brush or sponge to gently scrub the stain in circular motions. This can help loosen and lift the stain from the surface of the cup.
- If the stain is still present after scrubbing, you can try using a mixture of equal parts water and vinegar. Apply the mixture to the stain and let it sit for a few minutes before scrubbing again.
- Alternatively, you can use a commercial stain remover specifically designed for removing coffee stains. Follow the instructions on the package for the best results.
- Rinse the cup thoroughly with clean water to remove any soap or cleaning solution residue. Dry the cup with a clean towel or paper towel.
Remember to be gentle when scrubbing the cup to avoid damaging it. If the stain is still present after trying these methods, you may need to soak the cup in a solution of water and bleach for a longer period of time. However, be sure to rinse the cup thoroughly with clean water after soaking it in bleach to remove any residue.
Common mistakes
Some common mistakes that people make when trying to remove coffee stains from cups include:
- Using too much pressure when scrubbing: Scrubbing too hard or using too much pressure when trying to remove a stain can damage the cup or make the stain more difficult to remove. It is important to be gentle when scrubbing the cup to avoid damaging it.
- Using the wrong cleaning solution: Using the wrong cleaning solution or using too much of a cleaning solution can cause damage to the cup or leave behind a residue. Be sure to use a cleaning solution that is safe for the material of the cup and follow the instructions on the package for the best results.
- Not rinsing the cup thoroughly: It is important to rinse the cup thoroughly with clean water after cleaning to remove any soap or cleaning solution residue. If the cup is not rinsed thoroughly, the residue can cause additional staining or affect the taste of future beverages.
- Not drying the cup thoroughly: Allowing the cup to air dry can cause water spots or streaks to form on the surface of the cup. Be sure to dry the cup thoroughly with a clean towel or paper towel after cleaning to prevent this from occurring.
- Not treating the stain promptly: The longer a coffee stain is allowed to sit on a cup, the harder it can be to remove. It is important to treat the stain as soon as possible to increase your chances of successfully removing it.
