Grease stains on plastic containers can be challenging to remove due to the hydrophobic nature of grease, which makes it difficult to clean with just water. However, there are several effective methods to tackle this issue using common household products. These methods include using a combination of soap and water, vinegar, baking soda, bleach, hand sanitiser, and other degreasing solutions. The key steps involve initial surface grease removal, applying the chosen cleaning agent, allowing it to sit, and then thoroughly rinsing the container. While some people prefer hand washing, others suggest utilising the high-temperature settings on dishwashers for grease-cutting cycles. Additionally, preventative measures, such as lining containers with parchment paper or silicone liners, can simplify the cleaning process.

What You'll Learn

Using baking soda and water paste
To remove grease stains from plastic containers using baking soda and water paste, start by sprinkling 1 to 2 tablespoons of baking soda in the bottom of the container. Then, slowly add warm water and mix until you have a paste that is slightly thinner than toothpaste. Spread the paste all over the stained areas of the container, ensuring that all greasy surfaces are covered. Let the paste sit for about 5 minutes to 30 minutes.
Afterward, use a damp cloth to wipe the paste around, rubbing it well into the stained areas. Finally, rinse the container with warm water and dish soap to remove the paste and any remaining grease. You can also use your fingers or a sponge to ensure all the baking soda is washed away.
For an even more thorough cleaning, you can scrub the container with the paste using a cloth or a scrubbing brush. This method can effectively remove grease stains from plastic containers without causing damage.
Alternatively, you can first try wiping away excess grease with a paper towel or cloth before applying the baking soda paste. Additionally, you can substitute lemon juice for vinegar when creating the paste, as it can also help remove grease stains.

Soaking in a bleach solution
Prepare the Bleach Solution
Mix one tablespoon of bleach with ten parts water to make a potent bleach solution. You can make the solution in a sink, a container, or a bathtub. Always use caution when mixing bleach to avoid splashing it onto your clothes or bare skin. Wear protective gloves and clothing that covers your body to protect yourself from bleach splashes.
Soak the Plastic Containers
Submerge the plastic containers in the bleach solution for 5 to 10 minutes. Make sure the containers are completely covered by the solution. Use gloves when handling the containers to avoid skin irritation.
Scrub the Containers
After soaking, scrub the containers with a sponge or cloth to remove any remaining dirt or grime. Rub the sponge or cloth over the containers, focusing on areas with caked-on dirt or grease.
Rinse and Dry the Containers
Thoroughly rinse the containers with clean water to remove any bleach residue. Air dry the containers by letting them sit out for about 30 minutes or until they are completely dry.
Additional Tips
- Avoid exposing bleached plastic containers to direct sunlight immediately after cleaning, as this may enhance discolouration.
- Never mix bleach with other cleaning products inside the containers, as certain combinations can produce toxic gases.
- If you don't want to use bleach, you can try using vinegar, baking soda, or denture tablets as alternative cleaning solutions.

Using vinegar and water solution
Vinegar is an excellent natural cleaner, with its acidic properties working wonders in breaking down stain particles. Its effectiveness in removing grease, mildew, and hard water stains, as well as its disinfecting abilities, make it a popular choice for cleaning plastic containers.
To create a vinegar and water solution, mix equal parts white vinegar and warm water in a container. The ratio is important, as too much vinegar could damage the plastic, while too little might not be effective. For a large container, use one tablespoon of vinegar per cup of water.
Once you have prepared your solution, apply it to the stained plastic container. You can do this by pouring the solution directly into the container and letting it sit for 30 minutes to an hour. Alternatively, you can liberally spray or spritz the solution onto the stained areas, ensuring they are saturated.
After allowing the solution to sit, scrub the container with a clean cloth or sponge, paying extra attention to areas with built-up grime. Finally, rinse the container thoroughly with hot water and dry it with a towel.
If the stain persists, repeat the process or try another method, such as a baking soda paste or diluted bleach solution.

Soaking in hot water
Soaking your plastic containers in hot water is an effective way to remove grease stains. Here is a step-by-step guide on how to do it:
Step 1: Prepare the Soaking Solution
Fill your sink or a large container with hot water. The water temperature should be as hot as you can handle. Add a generous amount of dish soap to the water and mix it well to create soapy water. You can also add a cup of white vinegar or a small amount of bleach to enhance the cleaning power. If using bleach, be cautious and wear protective gloves.
Step 2: Soak the Containers
Completely submerge your greasy plastic containers in the hot, soapy water. Ensure that the water level is high enough to cover all the greasy areas. Let the containers soak for several minutes. The duration of soaking may vary depending on the severity of the grease buildup. For tough grease stains, you may need to let the containers soak for a more extended period.
Step 3: Scrub and Rinse
After soaking, use a sponge or a washcloth to scrub the containers and remove any remaining grease. You can also add a small amount of dish soap directly to the sponge for extra degreasing power. Rinse the containers thoroughly with plain water to remove any soap residue.
Step 4: Dry the Containers
Once the containers are free of grease, dry them thoroughly. You can place them on a drying rack or use a clean cloth to wipe them dry. Ensure no water spots or residue is left behind.

Using hand sanitiser
Grease stains on plastic containers can be a pain to get rid of, but hand sanitiser can be an effective solution. Here's a step-by-step guide on how to use hand sanitiser to remove those stubborn grease stains:
Step 1: Choose the Right Hand Sanitiser
Opt for a hand sanitiser that is free from added colours and fragrances. The absence of these additives ensures that your container doesn't retain any unwanted smells or discolouration. Additionally, choose a hand sanitiser that contains alcohol, as it is an effective solvent for breaking down grease.
Step 2: Apply the Hand Sanitiser
Pour or pump enough hand sanitiser onto the stained area of the plastic container to completely cover it. Make sure the hand sanitiser comes into direct contact with the grease stain. You may use your fingers or a clean cloth to gently work the hand sanitiser into the stained area.
Step 3: Let it Sit
Allow the hand sanitiser to remain on the stain for at least 30 minutes to an hour. During this time, the alcohol in the hand sanitiser will work to break apart the grease molecules, making it easier to remove the stain.
Step 4: Wipe and Wash
After letting the hand sanitiser sit, use a paper towel or a damp cloth to wipe away the hand sanitiser. You will notice that the grease stain transfers onto the paper towel or cloth as you wipe. Once most of the hand sanitiser has been wiped away, proceed to wash the container with warm water and dish soap. This final step will ensure that any remaining traces of the stain, as well as the hand sanitiser, are completely washed away.
Tips and Precautions:
- Hand sanitiser can be effective in removing stains, but it may require a significant amount, depending on the size and severity of the stain.
- Always wash the container with soap and water after using hand sanitiser to ensure that any residual hand sanitiser is rinsed away.
- If you're concerned about the environmental impact of using large quantities of hand sanitiser, consider alternative methods like vinegar, baking soda, or denture tablets.
By following these steps, you can effectively use hand sanitiser to remove grease stains from your plastic containers, leaving them clean and stain-free!
