Soak in tea or coffee
Tea or coffee soaks can be used to change the colour of white plastic to cream. However, it is important to note that not all plastics react the same way to tea or coffee soaks, and some may not change colour as easily as others.
To use a tea soak, start by preparing a strong cup of tea. Allow the tea to cool to room temperature, then pour it into a container large enough to submerge the plastic item. Place the plastic item in the tea and let it soak for several hours or until it has reached the desired colour. Remove the item from the tea and rinse it with water to remove any residue. Allow the item to air dry completely before use.
Alternatively, you can use coffee in the same way as tea. Prepare a strong cup of coffee and allow it to cool to room temperature. Pour the coffee into a container large enough to submerge the plastic item and place the item in the coffee. Let it soak for several hours or until it has reached the desired colour. Remove the item from the coffee and rinse it with water to remove any residue. Allow the item to air dry completely before use.
It is important to note that tea and coffee contain tannins, which can stain plastics. Therefore, it is recommended to test the soak on a small, inconspicuous area of the plastic item first to ensure that the desired colour is achieved without causing permanent staining.
In addition to tea and coffee soaks, there are other methods to change the colour of white plastic to cream. One method is to use sunlight to artificially age the plastic, giving it a cream colour. Simply leave the plastic item in direct sunlight for several days or weeks, checking periodically to ensure that the desired colour is achieved without causing discolouration. Sanding the plastic before exposing it to sunlight can also help to achieve the desired colour and texture.

Leave in the sun
Leaving white plastic in the sun is a simple and cost-effective method to change its color to cream. This technique utilizes the power of the sun's ultraviolet (UV) rays to initiate a chemical process that alters the plastic's pigmentation. Here's a detailed guide on how to achieve the desired cream color by exposing white plastic to sunlight:
Select an Outdoor Space: Choose an outdoor area that receives direct sunlight for extended periods. Ensure that the spot you select is relatively flat and free from obstructions that may cast shadows on the plastic, as consistent sunlight exposure is crucial for even color transformation.
Prepare the Plastic Surface: Clean the white plastic surface thoroughly using mild soap, water, and a soft cloth. Ensure that all dirt, dust, and grease are removed, as contaminants may hinder the sun's ability to bleach and discolor the plastic evenly. Once clean, allow the plastic to dry completely before proceeding.
Positioning the Plastic: Place the white plastic item in the chosen outdoor space. Orient it in a way that maximizes its surface area exposure to direct sunlight. If you're trying to change the color of a plastic container, for example, lay it on its side and rotate it periodically to ensure all sides are evenly exposed.
Sun Exposure Duration: The duration of sun exposure depends on the intensity of sunlight and the desired shade of cream. In general, leaving the plastic exposed for extended periods will result in a more pronounced color change. Start with a few hours of sun exposure daily, and gradually increase the duration by an hour or two each day. Inspect the color change periodically to ensure it's progressing as desired.
Monitor and Adjust: Regularly monitor the plastic's color transformation, especially during the initial phases. The rate of color change can vary depending on factors such as the type of plastic, the intensity of sunlight, and the ambient temperature. If you desire a lighter shade of cream, reduce sun exposure time accordingly. Conversely, for a deeper cream hue, extend the sunbathing duration.
Natural Fading Agents: To accelerate and enhance the color transformation, you can introduce natural fading agents. Lemon juice, for example, is a mild, natural bleaching agent. Dilute lemon juice with water and apply it to the plastic's surface using a soft cloth. Then, leave the plastic in the sun, and the combination of lemon juice and UV rays will expedite the color change.
By following these steps and regularly monitoring the process, you can effectively change white plastic to a desirable shade of cream using the power of the sun. This method is environmentally friendly and provides a unique, natural patina to plastic items.

Use peroxide cream
Peroxide cream is an effective way to lighten cream-coloured plastic that has turned yellow. It is commonly used to lighten hair, so it can be found at hair supply and beauty stores.
To use peroxide cream, it is recommended to put on a pair of gloves and safety goggles. Then, apply a thin layer of peroxide cream onto the stained plastic. Cover the plastic piece with plastic wrap and set it under sunlight or UV light for 12 to 24 hours.
If you are looking to remove stains from appliances and electronics, peroxide cream is a good option. It is important to note that this method may not be suitable for all types of plastic, and it is always a good idea to test on a small area first. Additionally, if you are working with electronics, it is recommended to remove the plastic pieces before treating them with peroxide cream.
Peroxide cream is a gentle and effective way to lighten cream-coloured plastic that has turned yellow due to sun exposure or other discolouration. It can be easily found at most beauty supply stores and is a cost-effective way to restore your plastic items to their original colour.
It is important to note that, while peroxide cream is a gentle and effective method, it may not work for all types of plastic or discolouration. In some cases, the discolouration may be too severe, or the plastic may not react to the peroxide cream. In these cases, it is recommended to try alternative methods, such as soaking the plastic in vinegar or bleach, or using a baking soda paste.

Soak in bleach
Soaking plastic in bleach is a common method used to remove yellow stains and restore the plastic to its original white colour. This technique is often applied to plastic toys, containers, utensils, and other items that have discoloured over time.
To effectively soak plastic in bleach, follow these steps:
Prepare the Bleach Solution
Dilute the bleach with water. The recommended ratio is 1 tablespoon (15 ml) of bleach to 1 cup (240 ml) of water. It is important to wear protective gear, such as gloves and safety goggles, when handling bleach.
Submerge the Plastic
Fully submerge the plastic item in the bleach solution. Ensure that the item is completely covered by the solution. This method is suitable for various plastic items, including containers, utensils, and toys. However, it is important to note that electronics and electrical appliances should not be soaked in bleach.
Soaking Time
Let the plastic item soak in the bleach solution for 1 to 2 hours. The duration may vary depending on the severity of the discolouration. For stubborn stains, a longer soaking time may be required. It is recommended to check the progress periodically to avoid over-bleaching.
Rinsing and Drying
After the desired soaking time has passed, remove the plastic item from the bleach solution. Rinse the item thoroughly with soap and water to remove any residual bleach. Finally, allow the plastic item to air dry completely before using it.
It is important to note that while bleach can effectively remove yellow stains and restore whiteness, it will not change the plastic to a different colour. Additionally, bleach may not always deliver a pure" white colour and may affect the smoothness of the plastic finish. Therefore, for specific colour changes and smooth finishes, alternative methods such as painting may be more suitable.

Scrub with baking soda paste
While it is not possible to change the colour of plastic from white to cream using baking soda, you can use it to remove yellow stains from white plastic.
To make a baking soda paste, pour some baking soda into a small cup or container. Add water slowly, mixing it with the baking soda until it forms a thick paste. You can also add dish soap to the paste. Moisten the plastic with a bit of water. Scoop up some paste onto a sponge or paper towel and rub the paste into the plastic in circular motions. Green cleaning expert Susan Stocker recommends "rubbing it really well" and "pressing hard so that you get the paste inside the little 'pores' of the plastic".
Let the paste sit for a few hours. Stocker suggests leaving it for a day before rinsing it off. You can also apply a little more paste after scrubbing so that it doesn't dry out too quickly, giving the paste "time to 'eat' the stains". Once the paste has been left to sit, scrub the stain and rinse the paste off with warm water. Finally, dry the plastic with a towel.
