Tea stains on plastic containers can be unsightly and stubborn, but they're not permanent. There are several ways to remove them using common household items. For example, a paste made of baking soda and water can be applied to the stained area and left to sit for up to 30 minutes before being rinsed and dried. Another option is to use a natural cleaning solvent like vinegar, which is safe and effective. Diluted bleach is a powerful cleaning agent but should be used with caution and followed by a thorough wash. For a hands-off approach, simply leaving the container in direct sunlight for a few hours can help to naturally remove stains and eliminate lingering scents.

What You'll Learn

Bleach
To use bleach to remove tea stains from a plastic container, start by mixing a solution of one part chlorine bleach with ten parts water. Apply this mixture to the stained area of the container using a sponge or damp cloth. Allow the solution to sit on the stain for 10-15 minutes before rinsing it off with water. It is recommended to avoid exposing bleached items, especially plastic containers, to direct sunlight immediately after cleaning, as this may enhance discoloration.
Alternatively, you can create a bleach soaking solution to remove tea stains from plastic containers. Mix one tablespoon of bleach with one cup of water, and let the container soak in this solution for one to two hours. After soaking, wash the container as usual.
While bleach is effective at removing tea stains, it may not be suitable for all situations. Bleach can leave a bad taste on items, and it can also fade colors and degrade plastic over time. Always use bleach in well-ventilated areas and follow the manufacturer's instructions for proper handling and dilution rates.

Vinegar
To remove tea stains from plastic containers, you can use a solution of vinegar and water. Mix equal parts of white vinegar and warm water. Soak the stained plastic in this mixture for about 30 minutes. Then, rinse the container thoroughly with hot water. It is important to note that vinegar can be too strong for some plastics, so it is recommended to dilute it with water to avoid potential damage to the plastic.
Another method is to fill a spray bottle with distilled white vinegar and cover the entire stain with vinegar. Wait 15-20 minutes, then rub the container with a warm cloth to remove the vinegar and the stain. Finally, rinse the container with warm water and wash it as usual.
While vinegar is effective in removing tea stains, it may not work for all types of stains. For tougher stains, you can add baking soda to the vinegar solution to boost its cleaning power. Simply make a paste by mixing baking soda with some water, apply it to the stain, and let it sit for 15-20 minutes before rinsing with warm water. Be careful not to scrub too hard, as baking soda is abrasive and could scratch the plastic.
Additionally, vinegar is great for removing odours from plastic containers. If you are mainly concerned about removing smells rather than stains, vinegar can be an effective solution.

Another method is to sprinkle a thin layer of baking soda inside the container, covering the tea stains. Add a small amount of water to create a paste.

The sooner you clean the stain, the easier it will be to remove.

Denture tablets
Step 1: Fill the Container with Warm Water
Start by filling the stained plastic container with warm water. The amount of water you use will depend on the size of your container. You want to ensure that the water level is high enough to completely cover the stained areas.
Step 2: Add the Denture Tablet
Take a denture tablet and drop it into the warm water. You may use a single tablet for a small container, but for larger containers, you may need two or more tablets to ensure effective cleaning.
Step 3: Allow the Tablet to Dissolve and Soak
Once the denture tablet is added, it will start to fizz and dissolve. Allow it to completely dissolve and then let the container soak. For light tea stains, a couple of hours of soaking may be sufficient. However, for heavily stained containers, it is recommended to let them soak overnight.
Step 4: Scrub and Rinse
After soaking, pour out the solution and scrub the container with a sponge or brush. The tea stains should come off easily. Finally, rinse the container thoroughly with hot water to remove any residue.
Additional Tips:
- While denture tablets are safe for most surfaces, always check the manufacturer's guidelines before using them on certain materials.
- Denture tablets can also be used to clean tea stains from mugs, kettles, coffee makers, and even jewellery.
- For extremely stubborn stains, you may need to repeat the process or try a different cleaning method.
By following these steps, you can effectively use denture tablets to remove tea stains from plastic containers, leaving them clean and stain-free.

Rubbing alcohol
If the stained item is a container, pour the rubbing alcohol into it and let it sit for a few minutes. If the item is not a container, you can pour the alcohol into something that can hold the item and allow it to soak. Once the stains disappear, rinse the item thoroughly and dry it.
Hand sanitizer can also be used to remove tea stains from plastic containers because its active ingredient is alcohol. Apply the hand sanitizer directly to the stain and let it sit for about an hour. Then, gently scrub the area with a moist cloth, rinse, and dry.
Be cautious when using hand sanitizer to avoid potential discoloration. Test a small area first before applying it to the entire stain. Do not leave the sanitizer on for more than an hour, and always remember to rinse thoroughly afterward.
