Red plastic can lose its vibrant colour over time due to various factors, including sun exposure, harsh weather conditions, and oxidation. While it is challenging to restore faded red plastic to its original state, several methods can improve its appearance. One common approach is to use a plastic restorer, which contains conditioning agents to reverse ageing and protect the surface. For hard plastics, creating a solution of soapy water and sandpaper can help restore the colour, while softer plastics may benefit from a mixture of detergent, household cleaner, water, and bleach. Additionally, some creative solutions, such as using peanut butter or specific products like Turtle Wax, can be explored. However, it's important to note that any intervention may degrade or weaken the plastic over time.

What You'll Learn
Use a heat gun
Using a heat gun is an economical and convenient way to restore faded red plastic. It offers a high degree of control, making it easy to adjust the intensity and direction of the heat to suit specific restoration needs.
Before using a heat gun, ensure you have the necessary safety gear, including heat-resistant gloves and safety goggles. Prepare the area by applying heat-resistant tape or protective sheets to surrounding areas that could be sensitive to the heat, such as glass, metal, and other plastic surfaces.
When using the heat gun, start by adjusting it to a low setting, usually around 200°F (93°C). Hold the gun around 6-8 inches away from the plastic surface and apply heat to a test area. Once you're satisfied with the results, move on to the actual restoration.
Hold the heat gun 4-6 inches away from the plastic and move it in a back-and-forth motion over a small section. Keep the heat gun moving to evenly distribute the heat and prevent the plastic from warping or burning. Continue heating until the faded plastic returns to its original colour, then move on to the next section.
After using the heat gun, you may want to consider additional steps to ensure the restored plastic retains its appearance. These steps can include sanding, polishing, and coating the plastic.

Try a plastic restorer
If your red plastic has faded, you can try using a plastic restorer to restore its colour. There are a few different products available that can help bring back the shine to your faded plastic items.
One such product is Carfidant Trim & Plastic Restorer, which claims to not only make dull plastic shine but also protect it from drying, aging, and fading. It is safe to use on all surfaces and colours of plastic and rubber. It is also easy to apply and mess-free. Simply apply it to the surface, leave it for a few minutes, and then buff it out with a microfiber cloth.
Another option is Polytrol Color Restorer, a deep-penetrating oil that restores the original colour and appearance of dull or tarnished plastics. It can be used on both horizontal and vertical surfaces and is simple to apply using a cloth or soft brush. It dries to a tough, flexible finish that does not peel or flake and provides long-lasting protection. However, it may not work on surfaces that have a clear coat applied over the coloured composite.
If you're looking for a more natural solution, you can try using vinegar and water to scrub the faded areas. This method works well for vinyl plastic, commonly found on exterior siding, car mats, computer cases, and gym mats. Mix vinegar and water in a spray bottle and spray the solution onto the faded areas. Then, use a clean sponge to scrub the solution into the surface.
For softer plastics, you can mix detergent, household cleaner, water, and bleach to create a spray solution. Put on protective gear, including rubber gloves and goggles, before handling this solution. Mix 1/3 cup of liquid laundry detergent with 2/3 cup of household cleaner, 1 quart of bleach, and 1 gallon of water. Add the mixture to a spray bottle and spray it onto the discoloured area. Let it soak for a few minutes before rinsing with cold water and then thoroughly washing the plastic with soap and water.

Sand it down
Sanding down faded plastic is an effective method to restore it. This method is particularly useful for hard plastics that haven't been painted, such as storage bins, cutting boards, acrylic aquariums, and plastic furniture. It's worth noting that any treatment to plastics will degrade or weaken them over time, so proceed with caution.
Firstly, fill a bucket with soap and water. Dip 150-grit sandpaper into the soapy water and rub the surface of the faded red plastic in a circular motion. Cover each faded area 5-6 times. This process will help remove any oxidation and restore the plastic's original colour.
Next, grab a sheet of 220-grit sandpaper and repeat the process. Again, ensure you cover each section 5-6 times before rinsing the surface. If there are any remaining scratch marks, you can continue using a finer grit sandpaper until the surface is smooth.
After sanding, it is important to rinse the plastic surface thoroughly with soap and water to remove any remaining residue. You can also try other methods, such as using a plastic restorer or a heat gun, but be cautious as the heat from the heat gun can damage paint and make the plastic more brittle over time.
Additionally, you can use this sanding technique in combination with other treatments. For example, after sanding, you can apply peanut butter to the plastic surface, leave it in a plastic bag, and then repeat the process several times until it shines. This combination of sanding and treating can enhance the restoration process. However, it's important to note that some treatments, like using a blow torch, may provide a temporary solution but can have negative long-term effects.

Bleach, detergent and water
Restoring faded red plastic with a solution of bleach, detergent, and water can be an effective method, but it is important to exercise caution. Bleach can be too harsh on certain plastics, so it is recommended to use diluted bleach and to test a small area first. Avoid using this method on coloured plastics, as bleach may alter the original hue.
Before attempting to restore the faded red plastic, it is important to clean the surface thoroughly with soap and water. This will help remove any dirt or grime that may be contributing to the fading. Additionally, regular cleaning can help prevent further fading by reducing micro-scratches that accelerate UV damage.
To make the solution, it is recommended to mix one-third cup (79 mL) of liquid laundry detergent with two-thirds cup (160 mL) of all-purpose household cleaner. Then, add one quart (950 mL) of bleach and one gallon (3.8 L) of water. Always wear thick rubber gloves and protective goggles when handling bleach and other chemicals.
Mix the ingredients together and pour them into a spray bottle. Take the faded red plastic item outside or to a well-ventilated area. Spray the discoloured areas generously with the solution, making sure to saturate the surface. Allow the solution to soak into the plastic for 2-3 minutes.
Finally, rinse the treated areas with cold water to remove any residue. Thoroughly wash the plastic item with soap and water to ensure that all traces of the solution are removed. Allow the item to air dry completely.
It is important to note that this method may not work for all types of plastic and that testing on a small, hidden area first is always recommended. Additionally, for deep discoloration, plastic dyes or paints may be a more effective solution.

Paint it
If your plastic item has been painted in the past, the only way to fix fading is to repaint it. Begin by placing the plastic item on top of a drop cloth outside. Then, spray the entire item with a spray primer designed for plastic. Wait 1-2 hours for the primer to dry. Next, grab a can of spray paint made for plastic and hold the nozzle 8–12 inches (20–30 cm) away from the surface. Move the can back and forth while holding the nozzle down to apply a layer of paint. You can also use a brush and an acrylic paint designed for plastic if you prefer. Wait 1-2 hours for the paint to dry.
Before painting, use masking tape to cover any surfaces that you don't want to get paint on. If you only paint the affected area, the new paint will clash with the older layers of paint.
If the plastic hasn't been painted, you can try other methods to restore its colour before resorting to paint. For hard plastics, fill a bucket with soap and water. Dip 150-grit sandpaper into the soapy water and rub the surface in a circular motion. Cover every faded area 5-6 times. Then, grab a sheet of 220-grit sandpaper and repeat the process. Cover every section 5-6 times before rinsing the surface off. You can continue using a finer grit sandpaper if there are any scratch marks remaining.
For softer plastics, mix 1⁄3 cup (79 mL) of liquid laundry detergent with 2⁄3 cup (160 mL) of all-purpose household cleaner. Add 1 US quart (950 mL) of bleach and 1 US gallon (3.8 L) of water. Put on thick rubber gloves and protective goggles, then pour the mixture into a spray bottle and apply it to the plastic. Let it soak for 2-3 minutes before rinsing the area with cold water. Wash your plastic thoroughly with soap and water after doing this.
