A yellowed plastic or fibreglass bathtub can be unsightly, and many cleaners for enamel bathtubs can be too harsh and abrasive for plastic tubs. The good news is that there are several methods to whiten yellowed plastic jacuzzi jets, including using a product like Salon Care 40 cream hair developer, which contains 12% hydrogen peroxide. Another method is to lightly sand the jets and spray them with appliance white spray paint, although it is important to note that only marine paint that is submersible would be suitable.

What You'll Learn

Hydrogen peroxide cream
To whiten yellowed plastic jacuzzi jets, you can use a cream containing hydrogen peroxide. This method is known as "retro-brighting" and has been used to restore old plastic gadgets and appliances.
Firstly, you need to purchase a cream containing hydrogen peroxide. One recommended product is Jerome Russell Bblonde cream peroxide (40 Vol 12%), which can be found at beauty supply stores or on Amazon. Alternatively, Salon Care, another brand, can be purchased from local beauty supply stores.
When applying the cream, it is important to wear plastic gloves to protect your skin. Use an old toothbrush or a small paintbrush to apply the cream liberally to the yellowed areas of the jacuzzi jets. Ensure that you cover all the areas you want to treat.
After application, cover the jets with plastic wrap to prevent the cream from drying out too quickly. Place the treated jets in direct sunlight or under a UV lamp. The UV light is essential to the whitening process, as it reverses the yellowing caused by sunlight/UV light exposure over time.
Leave the jets in the sun or under the UV lamp for at least 24 hours. Some sources suggest leaving them for up to 48 hours, depending on the severity of the yellowing. Check on the progress regularly, and if using sunlight, turn the jets regularly to expose all sides to the UV light.
Finally, after the required time has passed, rinse the cream off the jets thoroughly with water. Ensure that no residual cream remains on the jets.
It is important to note that this method may not work on all yellowed plastics, and the results may vary. Additionally, be cautious to avoid letting the cream dry under direct sunlight, as it may cause an irreversible bleaching effect.

Hair developer products
If you're looking to whiten yellowed plastic jacuzzi jets, one possible solution is to use hair developer products. Hair developer products contain a concentrated amount of hydrogen peroxide, and when combined with UV light, can reverse the process that causes white plastic to yellow.
Salon Care 40 cream hair developer, which contains 12% hydrogen peroxide, has been recommended by some as a cheap and easy way to whiten yellowed plastic jacuzzi jets. To use this product, wear plastic gloves and paint it onto the jets with an old small paintbrush. Cover the jets with plastic wrap and wait 24 hours before rinsing off. It may be necessary to repeat this process to achieve the desired results.
Alternatively, you can use a hair developer product with a lower volume of hydrogen peroxide, such as 20 or 30 volume, if you are concerned about the strength of the product on the plastic. These products can be purchased at beauty supply stores or online at Amazon or Walmart for around $5-10. When using these products, it is important to wear gloves and cover the item with plastic wrap to prevent the product from drying out. Leave the product out in direct sunlight or under indoor UV lights for 48 hours before rinsing.
It is worth noting that some people have reported that using a heat gun or Mr Clean Magic Erasers can also help remove yellowing from plastics, although it may not be as effective as using hair developer products. Additionally, it is important to thoroughly rinse off any hair developer product after the whitening process to avoid any residue.
Overall, using hair developer products is a cost-effective and relatively simple way to whiten yellowed plastic jacuzzi jets, and with a bit of time and effort, you can have your tub looking clean and bright again.

Spray bottle application
To whiten yellowed plastic jacuzzi jets using a spray bottle, you can use a common household product—hydrogen peroxide. Fill a spray bottle with 3% hydrogen peroxide, which can be purchased at drugstores or convenience stores.
Before applying the hydrogen peroxide, ensure that you move any fabric items such as bath mats, towels, and washcloths to a safe location, as hydrogen peroxide will bleach fabric. Also, remove any bathing or showering supplies, such as shampoo, soap, and shower caddies, from the bathtub area.
Then, simply spray the hydrogen peroxide onto the yellowed plastic jacuzzi jets. Allow the solution to soak for 10 to 15 minutes. Finally, wipe the jets with a wet, clean, non-abrasive sponge. If more whitening is needed, you can repeat the process until the yellowing is completely removed.
Alternatively, you can use a hair developer cream that contains 12% hydrogen peroxide, such as Salon Care 40. Wear plastic gloves and paint the product onto the jets with a small paintbrush. Cover the jets with plastic wrap and wait 24 hours before rinsing off. You may need to repeat this process for the best results.

Non-abrasive sponges
To whiten yellowed plastic jacuzzi jets, you can use a few different methods, including natural solutions like lemon juice and vinegar, or stronger cleaners like hydrogen peroxide and bleach. It's important to test any cleaning method on a small, hidden area first to ensure it doesn't cause further discolouration or damage. When using these methods, non-abrasive sponges are a key tool to ensure you do not scratch the plastic.
When using a non-abrasive sponge to clean yellowed plastic, it's important to be gentle and patient. Some stains may require multiple treatments, so it's essential to persist and not scrub too hard, which could damage the plastic. For example, when using lemon juice to clean yellowed plastic, you would gently rub the juice onto the stains with a sponge, let it sit for 10-15 minutes, then rinse and dry the plastic. Similarly, a diluted bleach solution can be applied gently with a sponge, left for a short time, then rinsed off. It's important to wear protective gear when handling bleach and to avoid mixing it with other cleaning agents.
Another method that can be used with a non-abrasive sponge is a baking soda paste. The paste is made by mixing baking soda with water, then applied to the yellowed plastic with the sponge. It should be left for a few hours, then scrubbed gently and rinsed off with warm water. This method may need to be repeated multiple times to fully remove the stain.
In summary, non-abrasive sponges are an important tool when cleaning yellowed plastic, as they prevent scratching and further damage. Natural sponges or soft, non-abrasive alternatives made from natural fibres are ideal. When used with gentle cleaning solutions and a patient, persistent approach, these sponges can effectively remove stains and restore yellowed plastic to its original brightness.

Soaking and rinsing
Soaking
Start by purchasing a hydrogen peroxide cream, such as "Salon Care," from your local beauty supply store. Put on some plastic gloves to protect your hands. Using a small paintbrush, carefully paint the cream onto the yellowed plastic jets. Make sure to cover all the discoloured areas evenly. Once you have applied the cream, cover the jets with plastic wrap. This step is essential to prevent the solution from drying out. You can use plastic wrap that sticks to the tub's surface, such as Press'n Seal or Cling Wrap.
Waiting and Repeating
Let the solution sit for 24 hours, then assess the progress. Depending on the severity of the discolouration, you may need to repeat the process. If the jets are still yellow, remove the plastic wrap and reapply the hydrogen peroxide cream. Cover them again with plastic wrap and let them sit for another 24 hours. Some people recommend putting the treated jets in the sun or using a UV light after applying the solution and covering them with plastic wrap. This step may enhance the whitening effect.
Rinsing
After the soaking and waiting process, it's time to rinse. Remove the plastic wrap and thoroughly rinse the jets with water to remove any remaining cream or residue. Ensure that you rinse the jets multiple times to eliminate any potential irritants before using the jacuzzi.
It is important to note that while this method has proven effective for many people, it may not work for everyone. The severity of discolouration and the type of plastic used in your jacuzzi jets can influence the outcome. Always exercise caution when handling chemicals, and if you are unsure, consult a professional or refer to your jacuzzi's manufacturer instructions for specific cleaning guidelines.
