Over time, the plastic on your fridge can turn from gleaming white to an unsightly yellow, making it look old and unsanitary. Fortunately, there are several ways to restore yellowed plastic to its original colour. For example, you can soak the plastic in a solution of vinegar and water, or submerge it in a bleach bath. You can also try using lemon juice, which, when combined with sunlight, can effectively whiten plastic. Alternatively, you can use a commercial cleaning product, but be sure to test it on a small, hidden area first to ensure it doesn't cause damage.

What You'll Learn
Using a lemon
If the plastic on your fridge has turned yellow, you can use a lemon to whiten it. Lemons contain acid, which interacts with UV rays from the sun to whiten the plastic. This method is similar to using lemon juice to lighten hair.
Prepare the lemon:
Cut a lemon in half. You can also use bottled lemon juice, but fresh lemons are usually more effective.
Apply the lemon:
Rub the lemon halves over the yellowed plastic on your fridge. Make sure to coat the area evenly and thoroughly. You can also use a spray bottle to apply lemon juice if you don't want to rub it directly with the lemon.
Allow it to sit:
Let the lemon juice sit on the plastic for a few minutes. This gives the acid in the lemon juice time to penetrate the discoloured areas and start the whitening process.
Place the item in the sun:
After a few minutes, transfer your fridge outdoors or to a sunny spot indoors. Avoid direct sunlight if your fridge has electrical components, as the heat can damage sensitive machinery. Place the item in a spot that receives indirect sunlight.
Let it sit in the sun for 3-4 hours:
The UV rays from the sun will interact with the lemon juice, helping to whiten the plastic. Leave the item in the sun for at least three hours for the best results.
Repeat if necessary:
If the yellowing is still visible, you can repeat the process. Try leaving the lemon juice on the plastic for a little longer before placing it in the sun, or leave the item in the sun for a longer period.
Other tips:
- If you are working on a small plastic item, you can soak it in lemon juice for an hour before placing it in the sun.
- For heavily stained plastic, rub the pith of the lemon directly onto the discoloured areas to help lift the stains.
- Always check weather reports before starting this process to ensure you have a few hours of sunlight.

Hydrogen peroxide
If the plastic in your fridge has turned yellow, there are a few methods you can try to restore it to its original colour. One of the most effective ways is to use hydrogen peroxide, which is an anti-fungal and disinfectant.
To start, gather the necessary supplies, including towels, nylon sponges, a bucket, distilled water, mild dish soap, and microfiber cloths, as well as gloves, safety goggles, and, of course, hydrogen peroxide. You can use regular liquid 3% hydrogen peroxide, or opt for a stronger cream peroxide, which ranges from 9-12% concentration and is available at hair supply stores.
If you're using liquid hydrogen peroxide, simply fill a plastic bag or container with enough peroxide to cover the yellowed plastic pieces. Submerge the plastic in the peroxide and set it out in direct sunlight for 3-4 hours. This process allows the peroxide to work on the discolouration and stains, lifting them from the plastic.
For cream peroxide, use a paintbrush or toothbrush to apply the product evenly to the plastic. Be sure to wear gloves to protect your skin. Then, place the plastic in a sealed bag and set it in direct sunlight, rotating it occasionally for even sun exposure. The UV light will react with the cream peroxide, reversing the yellowing effect.
If you're dealing with smaller plastic items, like stained plastic dishes or utensils, you can soak them in a hydrogen peroxide bath until the discolouration lifts. Alternatively, you can spray the interior of the fridge with hydrogen peroxide and let it sit for as long as possible before wiping it clean and repeating if necessary.
With these methods, you can effectively use hydrogen peroxide to restore yellowed plastic in your fridge to its original brightness.

Bleach
Once you have prepared the mixture, you can apply it to the yellowed plastic on your fridge. Use a sponge or cloth to wipe the solution onto the affected areas. Allow the bleach solution to sit for about 10 minutes. Then, use a clean, wet sponge to wipe the appliance again. You may need to repeat this process a few times for the best results. Make sure to wait the full 10 minutes each time you apply the solution.
Alternatively, you can try a stronger bleach solution by mixing 4 cups of water, 1/2 cup of bleach, and 1/4 cup of baking soda. Apply this mixture to the fridge and let it sit for 10 minutes before rinsing. This stronger solution may be more effective on severe stains.
When using bleach, always exercise caution and follow safety guidelines. It is important to dilute the bleach to prevent any damage to the plastic. Additionally, make sure the area is well-ventilated to avoid inhaling bleach fumes. Keep bleach away from children and pets.
If you are hesitant to mix your own bleach solution, you can explore commercial cleaners designed to remove yellowing from white plastic. These products offer a convenient alternative to homemade solutions and can be found at most home improvement or hardware stores.

Vinegar
To use vinegar to rewhiten yellowing plastic, start by mixing equal parts vinegar and water. You can either apply this mixture to the affected areas and scrub gently or place the plastic item directly into the solution and let it soak for several hours or overnight. If you're dealing with a larger appliance like a fridge, you might find it easier to simply spray the vinegar solution onto the yellowed areas. After letting it sit, scrub gently and then rinse with water.
If you want to enhance the whitening effect, you can try adding baking soda to the vinegar solution. Sprinkle baking soda over the vinegar-soaked plastic, and this will create a paste that can help lift stains and restore the plastic's original colour.
It's important to note that while vinegar is a safe and effective option, it may not produce immediate or dramatic results, especially for heavily stained or discoloured plastic. For more severe cases of yellowing, you may need to repeat the vinegar treatment multiple times or explore other whitening methods.
Additionally, when working with vinegar, it is recommended to wear cleaning gloves to protect your hands, as vinegar can sting any cuts or scrapes on your skin. Always be cautious when handling any cleaning solutions, and ensure the area is well-ventilated.

Sunlight
If you are using a 3% peroxide solution, leave the appliance in the sunlight for as long as possible. The more diluted the solution, the more time it will take to work. Bring the item inside and rinse the cream off with a wet cloth. If you still notice some yellowing, wait for the appliance to dry completely and then reapply the peroxide cream and repeat the process.
You can also use a lemon to whiten the plastic. Cut a lemon in half and rub both parts over the yellowed part of your appliance. Leave the juice to sit on the plastic for a few minutes, then transfer the appliance outdoors. Set it in a spot that receives decent sunlight but not too much direct light, as the heat may cause damage to the machinery of your appliance. The lemon method is also a safe way of whitening children's toys.
Another method is to create a baking soda paste and apply it to the yellowed plastic. Mix water and baking soda until it forms a paste, then apply it to the plastic and let it sit for several hours. Then, scrub the paste off with a sponge or rag and rinse well. For this method, sunlight is the key to ending the staining.
