Faded plastic is a common issue, especially in items exposed to sunlight, such as patio chairs, car trims, and garden tools. The good news is that there are several ways to restore water-faded plastic, ranging from DIY solutions to professional-grade restorers. For instance, a mixture of baking soda and water can be rubbed into the plastic, or a solution of vinegar and water can be used to scrub the surface. Soaking plastic in hydrogen peroxide (3% concentration) under sunlight can reverse discolouration. For a more long-lasting solution, a ceramic coating can be applied to seal and protect the plastic.
| Characteristics | Values |
|---|---|
| For hard plastics that haven’t been painted | 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. |
| Faded plastic that isn’t discoloured | Caused by oxidization. Remove oxidation using a cleaning solution. |
| Softer plastics | Use detergent, cleaner, and bleach. Mix 1/3 cup of detergent, 2/3 cup of cleaner, 1 quart of bleach, and 1 gallon of water. Spray the mixture on the plastic, let it soak for 2-3 minutes, then rinse. |
| Headlights | Clean them thoroughly and use white vinegar and water to restore them. |
| Plastic with painted surfaces | Protect with masking tape. Use a heat gun to restore the plastic. |
| Discoloured plastic on vehicles | Usually a combination of dirt and sun damage. Use a heat gun to melt the discoloured layer off. |
| Plastics with deep fading, yellowing, or long-term exposure damage | Soak in hydrogen peroxide (3% concentration) under sunlight to reverse discolouration. |
| Soft outdoor plastics like chairs, patio furniture, or toys | Use a diluted mix of bleach, mild detergent, and water to clean and brighten. |
| Preventing plastic from fading | Apply a UV-resistant sealant like Graphene VRT or 303 Aerospace Protectant. |
| Permanent restoration of black plastic trim | Clean the plastic trim with isopropyl alcohol, then apply Solution Finish Trim Restorer. |
| Long-lasting restoration | Use a ceramic-based trim restorer, or a product like CERAKOTE. |
| Short-term restoration | Use quick-fix fillers like WD-40, Vaseline, oils, or peanut butter. |

What You'll Learn
Use soapy water and sandpaper
To restore water-faded plastic, you can use soapy water and sandpaper. This method works best on rigid plastics like bins or outdoor fixtures and reveals a brighter layer underneath. The soap acts as a lubricant, helping to avoid scratches.
First, ensure your plastic is very clean. Use warm soapy water and a towel to dry the plastic. Next, fill a bucket with soap and water. Then, 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, rubbing in the same way. 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 on the plastic.
Always follow manufacturer instructions, and consider wearing gloves to avoid skin irritation. Remember to dry the plastic thoroughly to prevent water spots or mineral buildup. Regular cleaning helps keep plastic surfaces smooth, preventing micro-scratches that accelerate UV damage.

Bleach, detergent and water
Bleach, detergent, and water can be used to restore faded plastic, but caution must be exercised as bleach can weaken plastic fibres, alter the original colour, and even cause cracking or discolouration. It is therefore important to always dilute bleach and test it on a small area first.
To restore softer plastics, mix one-third of a cup (79 mL) of liquid laundry detergent with two-thirds of a cup (160 mL) of all-purpose household cleaner. Then, add one US quart (950 mL) of bleach and one US gallon (3.8 L) of water. Combine the ingredients and pour them into a spray bottle. Take the faded plastic outside and spray the discoloured area. Allow it to soak for 2-3 minutes, then rinse the area with cold water. After this, wash the plastic thoroughly with soap and water.
Before applying any restoration treatment, it is important to clean the plastic surface thoroughly with soap and water to remove any dirt, dust, oils, or debris. This helps to improve adhesion and achieve more even results. A thorough cleaning can also be achieved by using a mixture of liquid laundry detergent and warm water. Following this, dry the plastic completely with a clean, dry cloth or let it air-dry.
For mild fading, a diluted solution of bleach and water can be applied to the affected area. Alternatively, equal parts of bleach and water can be combined and the plastic can be soaked overnight in this solution. The plastic should then be rinsed, and left in sunlight for two days.
It is important to note that this method of restoration using bleach, detergent, and water is not suitable for coloured plastics as bleach may alter the original colour.

Vinegar and water
To restore water-faded plastic using vinegar and water, you can try the following methods:
For vinyl plastic
Mix a solution of 5 parts hot water to 1 part white vinegar, then spray it onto vinyl or soft plastics. Leave the solution on the surface for a few minutes before wiping it off. This method is an eco-friendly option for light surface discolouration.
For car headlights
Clean the headlights thoroughly and use a mixture of white vinegar and water to restore them. Protect any painted surfaces surrounding the plastic with masking tape.
For car mats, computer cases, and gym mats
Spray the plastic with vinegar and water. If the plastic is still faded, scrub the mixture into the surface with a clean sponge.
For other plastic items
Mix baking soda and water to form a thick paste, then rub it into the plastic.

Baking soda and water
To use this method, create a paste by mixing baking soda with a few drops of water. Apply this paste to the faded area of the plastic and rub it in with a soft cloth, using circular motions. Ensure you rub gently to avoid scratching the plastic. Once complete, rinse the plastic thoroughly with clean water and dry the surface.
For tougher oxidation, a stronger cleaning solution may be required. One option is to create a vinegar and baking soda bath for the plastic to soak in. Leave the plastic in this solution for several hours, then rinse off with clean water.
Another option is to create a thicker paste using baking soda and water, and really work this into the plastic. This method is particularly effective on vehicle plastics, which typically fade due to a combination of dirt and sun damage.
For very tough oxidation, a commercial plastic restorer may be required to fully restore the plastic.

Professional-grade restorer
If you're looking for a professional-grade restorer to address water-faded plastic, there are several options available that offer effective and long-lasting results. Here are some detailed instructions and recommendations for choosing and applying these products:
Firstly, it is important to understand the type of plastic you are working with and the extent of the fading. Different types of plastics require specific restoration methods. Hard plastics, such as storage bins, cutting boards, and plastic furniture, can often be restored using sandpaper and soapy water. Soft plastics, on the other hand, may require a different approach, such as a diluted mix of bleach, detergent, and water.
Ceramic-Based Restorers
For a professional and durable solution, consider using a ceramic-based plastic restorer. These products, such as IGL Ecocoat Trim, offer enhanced resistance to UV rays and water damage. By creating a protective barrier, they prevent further fading and deterioration. Ceramic-based restorers are known for their longevity, with some products claiming to last up to a year or more, even in diverse climates.
Silicone-Free Formula
Another professional option is to use a silicone-free formula restorer. This type of product penetrates deep into the plastic rather than just coating the surface. It is especially suitable for severely faded or oxidized black trim. While it may come with a higher price tag and require protective gear during application, the results are long-lasting and effective.
UV Protection
To prevent future fading, look for restorers that offer UV protection. Products like Solution Finish and TriNova Plastic & Trim Restorer include UV protection, shielding the plastic from sun damage. This helps prolong the restored look and maintains the appearance of your plastic items.
Application Process
When using professional-grade restorers, always follow the manufacturer's instructions carefully. Clean the surface thoroughly with soap and water, removing all dirt, dust, and oils. If needed, lightly sand the surface to improve adhesion. Then, apply the restorer using a microfiber or foam applicator, ensuring you wear protective gear, such as gloves and eye protection. Allow the product to dry completely before determining if a second application is necessary.
By following these instructions and choosing a high-quality professional-grade restorer, you can effectively restore water-faded plastic and protect it from future damage.
