What You'll Learn
Using baking soda
Baking soda is a natural ingredient that can be used to gently scrub away stains and odours from plastic containers. It is especially useful for removing tea dyes from plastic pitchers. Here are some methods you can try:
Baking Soda and Water Paste
Make a paste by mixing baking soda and water. The paste should be a little thinner than toothpaste, so it spreads easily but is not runny. Apply this paste to the stained areas of the container and let it sit for 30 minutes to 2 hours. Then, wipe the paste away with a damp cloth or sponge, rubbing it well, and rinse with warm water and dish soap.
Baking Soda and Lemon
After sprinkling the container with baking soda, use half a lemon as a sponge. Rub the lemon into the baking soda and around the surface of the container. Rinse well and dry thoroughly before storing. The acid from the lemon can also be used with the sun's UV rays to fade stains and kill bacteria.
Baking Soda and Salt
For stubborn stains, use a two-part method of baking soda and salt. Sprinkle salt onto a damp cloth and rub it into the stained plastic in small circular motions before rinsing the container.
Baking Soda and Vinegar
Baking soda can also be used with vinegar to remove tomato sauce stains and other aromas. Mix equal parts water and vinegar, pour the solution into the container, and let it soak for 2 to 3 hours. Then, wash and dry the container.
Removing Odours
If the baking soda removes the stain but not the food odours, crumple some newspaper and pack it into the container. Seal the container and let it sit for 1-2 days, then wash with hot soapy water.

Hand sanitiser
To remove hand sanitiser stains from plastic, you can use white vinegar, which is known to be effective in breaking down stain particles. It is also non-abrasive, so it will not damage the plastic material. Mix 1-2 tablespoons of white vinegar with equal amounts of water in a small bowl. Dab a dry microfiber cloth into the solution and use it to wipe down the stained area.
Alternatively, you can use a mild dish soap. Add 1 part of any mild dish soap to 10 parts of water in a small bowl and mix well. Dip a microfiber cloth into the solution and use it to wipe down the stained area, then dry the surface with a different cloth.
For tougher stains, you can try using baking soda. Sprinkle a thick layer of baking soda on the bottom of the container, then sprinkle water over it to form a thick paste. Spread the paste over the stained areas and let it sit for 30 minutes. Rinse the paste away, then wash the container with hot soapy water and air dry.
If the stain still persists, you can try using a commercial cleaner. However, be sure to choose one that is safe for use on plastics and does not contain any harsh chemicals or abrasive ingredients, as these can scratch the surface.

Bleach
Step 1: Prepare the Bleach Solution
Mix one part chlorine bleach with ten parts water. This will create a potent bleach solution. For example, mix one tablespoon of bleach with one cup of water.
Step 2: Apply the Bleach Solution
Using a sponge or damp cloth, apply the bleach solution to the stained area of the plastic container. Make sure to wear rubber gloves to protect your skin from irritation.
Step 3: Let the Solution Sit
Allow the bleach solution to sit on the stained area for 10 to 15 minutes. You can let it sit for up to 45 minutes for tougher stains. Do not let it sit for too long, as it can eventually eat away at the plastic and may result in discolouration.
Step 4: Rinse and Wash
After the solution has sat for the desired amount of time, thoroughly rinse the container with fresh, clean water. Wash the container with hot, soapy water to ensure no residue or bleach remains.
Step 5: Dry the Container
Completely dry the container by draining all water and wiping it down with an absorbent towel. You can also let it air dry with the lid off until all moisture has evaporated.
Safety Precautions:
- Always wear gloves when handling bleach to protect your skin.
- Use bleach in a well-ventilated area to avoid inhaling harmful fumes.
- Never mix bleach with other cleaners inside the plastic containers, as certain combinations can produce toxic gases.
- Avoid exposing bleached plastic containers to direct sunlight immediately after cleaning, as this may enhance discolouration.
- Always test bleach solutions on a small, hidden area of the plastic container first to ensure it won't harm or discolour the plastic.
By following these steps and safety precautions, you can effectively use bleach to remove stains from your plastic containers.

Lemon juice
Prepare the Lemon Juice
Start by extracting fresh lemon juice. Roll an uncut lemon on a countertop, applying gentle pressure with your palm to soften it and make it easier to squeeze. Cut the lemon in half and squeeze out the juice. You can also use store-bought lemon juice or lemon concentrate if you prefer.
Apply Lemon Juice to the Stained Area
Pour or squeeze lemon juice directly onto the stained area of your plastic container. Make sure to cover the entire stained surface. Lemon juice acts as a natural bleach, and its acidity will penetrate the stain, helping to lift it off the plastic.
Use Lemon Juice with Salt for Extra Scrubbing Power
For stubborn stains, combine lemon juice with salt to create an effective scrubbing mixture. Sprinkle salt generously over the stained area, then squeeze lemon juice onto the salted surface. The tiny grains of salt act like miniature scrub brushes, helping to dislodge stain particles from the plastic.
Allow the Lemon Juice to Work Its Magic
Let the lemon juice sit on the stained area for a while. The exact time may vary depending on the severity of the stain. For lighter stains, a few minutes might be sufficient, while deeper stains may require a longer soaking time.
Rinse and Repeat If Necessary
After allowing the lemon juice to work, thoroughly rinse the plastic container with warm water. If the stain has faded but is still visible, you can repeat the process until the stain is completely removed.

Dish soap and water
To use this method, start by adding a few pumps or drops of liquid dish soap to your stained container. Then, add some warm water. The exact amount of water is flexible, but aim for enough to cover the bottom of the container. Next, tear up a few pieces of paper towel and put them into the container as well. Secure the lid on the container and shake vigorously for 45 seconds to a minute. Finally, rinse the container with clean water to remove the soapy water and paper towel residue.
If you are dealing with a greasy or stubborn residue, you can try a slightly different method. Begin by running the container under warm water to loosen the grease. Then, fill the container with liquid dish soap and warm water. Allow the container to sit for several minutes. Finally, scrub the container clean using the soapy water and a scrubber, sponge, or nylon bristle brush if necessary.

Frequently asked questions
There are several ways to remove stains from plastic containers. You can use baking soda, hand sanitiser, bleach, vinegar, lemon juice, or dish soap.
It depends on the type and extent of the stain. For stubborn, set-in stains, bleach is the strongest option. However, it is important to note that bleach can be dangerous and harmful to human health if not used properly. For a more natural approach, lemon juice and sunlight can work well together to remove stains.
To prevent plastic containers from staining, avoid heating containers filled with tomato-based sauces in the microwave. You can also line containers with silicone cups or use silicone or glass containers for foods with tomato sauce.
