What You'll Learn
Use a non-abrasive, non-corrosive cleaner
To whiten a yellowed plastic shower, you can use a non-abrasive, non-corrosive cleaner. This method is particularly useful if the discolouration is due to exterior staining.
First, clean the shower thoroughly with a non-abrasive, bleach-free cleaner. You can use a mild detergent, or an all-purpose household or bathroom cleaner. You can also use shampoo or body soap. If you're using a liquid cleaner, mix an ounce of it in a gallon of water and scrub with a sponge or plastic scrubbing pad.
Next, you can use a paste made from baking soda and water. Scrub the paste into the plastic with a sponge or plastic applicator.
Another option is to use white distilled vinegar. Spray the vinegar directly onto the stains, let it sit for a few minutes, and then scrub it off.
If you want to remove stains caused by dye, paint, or pigments, you can use acetone or turpentine. Wipe these solvents onto the plastic with a soft cloth.
Be sure to avoid using bleach, as it is corrosive and may discolour the plastic further.

Try a peroxide-based acne cream
If you want to whiten your shower's yellowed plastic, one method you can try is using a peroxide-based acne cream. This method involves using a product like Benzoyl Peroxide, which is a medication that comes in the form of a skin cream, gel, or lotion and is used to treat mild to moderate acne. You can find this product under brand names such as Acne Medication, Acne-10, Acneclear, Benzac, and more.
Before using any peroxide-based acne cream, it is important to take certain precautions. For instance, avoid using other products that dry the skin, such as abrasive cleaners or products containing alcohol. Do not use other acne products on the same areas of the skin unless advised by a healthcare professional. Additionally, this medication can increase sun sensitivity, so it is recommended to stay out of the sun, or if exposure is unavoidable, wear protective clothing and sunscreen.
When using the acne cream to whiten yellowed plastic, it is important to protect yourself with rubber gloves and goggles. You can fill a bucket with hydrogen peroxide and add ¼ teaspoon of Oxy laundry booster for each gallon of peroxide. Wet a paper towel with this solution, squeeze out the excess, and press it against the yellowed plastic surface. If needed, you can use plastic wrap and tape to keep the paper towel in place. The whitening process can take anywhere from 2 to 6 hours.
While this method can be effective, it is important to note that it may not work on all types of yellowed plastics. Additionally, it is crucial to prevent the cream from drying up, especially under direct sunlight, as it can cause irreversible bleaching or streaking effects. Regularly check on the progress and turn the plastic items to ensure even exposure to sunlight. If practical considerations make it challenging to monitor the process closely, consider using a UV lamp to provide the necessary UV light without the heat.

Use a mixture of vinegar and borax
If your plastic shower has yellowed, it's likely due to exterior staining or simply from ageing. A mixture of vinegar and borax can effectively remove these stains. Vinegar contains acetic acid, which dissolves the salts in hard water that may have caused the yellowing.
To start, mix vinegar with borax to create a paste. You can adjust the ratio of vinegar to borax until you achieve a thick, cake batter-like consistency. Spread this paste liberally over the discoloured areas of your shower. To prevent the paste from drying out, periodically spray it with vinegar. After about an hour, scrub the paste off. If the yellowing is particularly stubborn, you may need to repeat this process.
For extra cleaning power, you can also add baking soda to your vinegar and borax paste. This combination is especially useful for caked-on gunk and soap scum buildup. Mix one cup of baking soda, one tablespoon of water, and adjust the amount of vinegar and borax until you achieve the desired consistency.
Before applying any paste, ensure the shower surface is damp to prevent scratching. Additionally, always ensure proper ventilation by opening windows and turning on fans. This is important whenever using any cleaning products.

Soak paper towels in bleach and cover the plastic
If you want to whiten yellowed plastic in your shower, one method is to use bleach. However, it is important to note that bleach may weaken the plastic over time. If you decide to use bleach, the following is a step-by-step guide:
Prepare the Bleach Solution
Fill a bucket or large bowl with one part bleach and one part water. The amount of the solution depends on the size of the yellowed plastic area. Make sure to wear gloves when handling bleach, as it is very strong.
Soak the Paper Towels
Submerge paper towels in the bleach solution until they are thoroughly soaked. If the plastic item cannot be submerged in the bucket, you will need to use the paper towel method described below.
Apply the Soaked Paper Towels to the Plastic
Remove the soaked paper towels from the bucket and cover the yellowed plastic with them. Firmly press the paper towels against the surface of the plastic, ensuring they are in contact with the discoloured area. If the paper towels start to dry out, re-wet them with the bleach solution using a spray bottle. Be careful not to let the bleach solution come into contact with surrounding areas, as it may discolour them.
Remove the Paper Towels
Once the plastic has reached the desired level of whiteness, carefully remove the paper towels. Rinse the plastic thoroughly to remove any remaining bleach residue. If necessary, wash the area with dish detergent and water to ensure all traces of bleach are gone.
Alternative Methods
There are alternative methods to whiten yellowed plastic, such as using hydrogen peroxide or Retrobrite. These methods may require the use of UV light or sunlight to activate the whitening process. Additionally, baking soda and vinegar can be used, but this method requires more effort and "elbow grease".

Use a commercial cleaner like Comet
To whiten a yellowed plastic shower, you can use a commercial cleaner like Comet. This is a mild abrasive cleanser designed for tubs, sinks, showers, and countertops. It is available in powder and soft cleanser form, with the latter containing bleach.
Before using Comet, it is important to moisten the plastic shower surface. Place the cleaner on a scrubbing sponge and scrub the yellowed areas. This process requires effort and time, but will effectively remove the yellow stains. Once the yellow stains are removed, wash the shower with water and dish detergent, and then rinse it thoroughly with clean water. Allow the shower to air dry completely.
While Comet can be an effective solution, it is important to note that some sources advise against using powdered or abrasive cleaners on fiberglass surfaces, as they can damage the thin gel coat and make it more difficult to clean in the future. Therefore, it is crucial to exercise caution and consider the material of your plastic shower before using Comet or any other commercial cleaner.
Additionally, it is always important to follow the manufacturer's instructions when using any commercial cleaner. Some cleaners may need to be diluted with water before use, while others can be used directly from the bottle. Always test the cleaner on a small, inconspicuous area first to ensure it does not cause any damage to the surface.
By following these steps and using Comet or a similar commercial cleaner, you can effectively whiten a yellowed plastic shower and restore its original shine.

Plastic turns yellow due to a chemical reaction when it is exposed to light, oils, and other substances.
You can use a variety of products, including:
- Bleach
- Comet cleaner
- Hydrogen peroxide
- Oxy laundry booster
- Baking soda and vinegar
- Oven cleaner
You can prevent yellowing by limiting the plastic's exposure to light, especially UV light.
