What You'll Learn

Using baking soda
Coffee stains on plastic can be difficult to remove, but baking soda is a gentle abrasive that can help scrub them away. It is a natural cleaning agent that can absorb the stain and remove it from the plastic.
To use baking soda to remove coffee stains from plastic containers, start by sprinkling one to two tablespoons of baking soda into the container. Then, slowly add warm water to create a paste. The paste should be slightly thinner than toothpaste, so it spreads easily but isn't too runny.
Once you have the right consistency, smear the paste all over the stained areas of the container. Let the paste sit for 10 to 30 minutes. The longer you leave it, the more effective it will be at breaking down the tannins and oils in the coffee.
After the paste has had time to work, use a damp cloth to wipe it around the container, paying particular attention to the stained areas. Then, rinse the container with warm water and dish soap to remove any residue.
If there are still stubborn stains, you can use a damp toothbrush to scrub them away with baking soda. Be sure to rinse the container thoroughly with warm water to remove any traces of baking soda.
The baking soda method is a safe and natural way to eliminate coffee stains from plastic containers. It is also environmentally friendly and helps reduce your carbon footprint.

Bleach
To use bleach for stain removal in plastic containers, create a bleach solution by mixing one part chlorine bleach with ten parts water. Apply this mixture to the stained areas of your plastic containers using a sponge or damp cloth. Allow the solution to sit on the stains for 10 to 15 minutes before rinsing thoroughly with warm water. It is important to ensure that the container is thoroughly rinsed and free of any bleach residue before using it again.
While bleach is effective in removing stains, it may not be suitable for all types of plastic containers, especially those used for food storage. In such cases, it is recommended to use alternative methods, such as vinegar, baking soda, or oxygen bleach, which are gentler on plastic and safe for food contact. Oxygen bleach, also known as Oxiclean, can be dissolved in boiling water to effectively remove coffee stains without the same risks associated with chlorine bleach.
When using bleach or any other cleaning agent, it is important to follow the instructions and take the necessary precautions to ensure your safety. Always test the solution on a small area of the plastic container before applying it to the entire surface, especially if it is a coloured container, to ensure that it does not cause discolouration. Additionally, never mix bleach with other cleaning agents or substances, as it can cause dangerous chemical reactions.
By following these instructions and taking the necessary precautions, you can effectively use bleach to remove coffee stains from your plastic containers, restoring them to their original condition.

Lemon juice
To use this method, start by removing any leftover coffee grounds and filters from your plastic container. This ensures that the lemon juice can effectively remove the coffee stains without any interference from used coffee grounds or filters. Next, rub the stained areas of the container with lemon juice. You can also sprinkle salt on the stained areas before applying the lemon juice, as the tiny grains of salt will act like mini scrub brushes that can help dislodge the stain particles.
After applying the lemon juice, leave the container in direct sunlight for one to two days. The sun's UV rays will work together with the lemon juice to remove the stains. If you don't have access to direct sunlight, you can also let the lemon juice sit on the stains for a few minutes before rinsing.
Finally, rinse the container thoroughly with warm water and allow it to dry. Repeat this process if necessary until all discolouration is removed.
While lemon juice is a natural and effective way to remove coffee stains, it may take some time for the process to work. For quicker results, you may want to consider using commercial cleaning products or other household items such as baking soda, vinegar, or hand sanitizer.

Soapy water
Initial Steps:
Firstly, it is important to remove any remaining coffee grounds or filters from the container. This can be done by gently tapping the container against a trash bin or compost container. For more stubborn residues, a simple initial soak in warm water for around 15 minutes can help loosen the coffee stains.
Prepare Soapy Water:
Fill a sink or large bowl with warm water and add a mild dish soap to create a mix of soapy water. The water should be warm, not hot, to avoid any potential warping or damage to the plastic. The amount of soap will depend on the size of your container, but aim for a few pumps or a generous drizzle of soap. You can also add a few drops of regular dish soap to a wet scrubby sponge and scrub the stained areas.
Soak or Scrub:
There are two main methods to use the soapy water: soaking or scrubbing. For the soaking method, place the plastic container inside the sink or bowl filled with soapy water and let it soak for at least 15 minutes. This will help lift any remaining stains. For more stubborn stains, use a clean cloth or sponge to gently scrub the stained areas while the container is soaking.
Alternatively, for the scrubbing method, use a clean cloth or sponge soaked in the soapy water to scrub the stained areas directly. Pay particular attention to any stubborn spots, and gently scrub them until the stains start to lift.
Rinse and Dry:
After soaking or scrubbing with soapy water, thoroughly rinse the container with clean water to remove any soap residue. Shake off any excess water, and then let the container air dry completely. Ensure that all soap residue is removed, as it can leave a film or discolouration if not properly rinsed.
By following these steps, you can effectively use soapy water to remove coffee stains from plastic containers, restoring their appearance and functionality.

Vinegar
To use vinegar to remove coffee stains from a plastic container, start by mixing equal parts vinegar and water. For every gallon of water, use two cups of vinegar. You can also use a ratio of one tablespoon of vinegar to one cup of water. Soak a clean cloth in the solution and apply it to the stain. Leave the solution on the stain for a few minutes. Then, wipe the area with a clean, damp cloth and dry it with a clean, dry cloth.
For more stubborn stains, you can try the baking soda and vinegar method. First, mix equal parts baking soda and water to form a thick paste. Apply the paste to the stained areas of the container and let it sit for about 10-15 minutes. Next, pour a solution of equal parts vinegar and water onto the baking soda paste and allow it to fizz. Once the fizzing stops, scrub the stained areas gently with a soft brush or sponge. Finally, rinse the container thoroughly with water and let it dry.
If your container is very stained, you can try soaking it in the vinegar solution for one to two hours before scrubbing and rinsing. You can also try an initial soak in warm water for 15 minutes to help loosen the stains before applying the vinegar solution.
