What You'll Learn
Use a plastic restorer like Mothers Back to Black or Plastic Renew
To restore the colour of your bicycle plastic, you can use a plastic restorer like Mothers Back to Black or Plastic Renew. Mothers Back to Black is a plastic restorer that removes light oxidation, dirt, wax residue and surface film, restoring the original colour of the plastic. It also protects against deterioration caused by sun exposure, smog, ozone, water, chemicals and airborne contaminants.
Before applying Mothers Back to Black, it is recommended to clean the plastic surface with a mild detergent and water. Then, using a soft cloth or the Mothers applicator sponge, apply the product to the plastic surface in small circular motions. Allow the product to absorb into the plastic for several minutes, and then buff off any excess product with a clean, dry cloth.
It is important to note that sanding the plastic surface before applying the restorer is not necessary but can be beneficial. Sanding allows the product to stick and absorb better, resulting in a more even and durable finish. However, it can add significant time to the restoration process.
Plastic Renew is another popular option for restoring bicycle plastic. It is essential to note that this product may require you to sand down the plastics beforehand, as mentioned in some reviews. While the exact process for applying Plastic Renew is not readily available, it is likely similar to Mothers Back to Black, involving the application of the product, absorption, and buffing.
Both Mothers Back to Black and Plastic Renew are effective in restoring the colour of bicycle plastics, and the choice between the two depends on personal preference and the specific requirements of the restoration project.

Sand down the plastic to remove scratches and reveal a new layer
Sanding down the plastic on your bicycle is a great way to remove scratches and restore its colour. It is important to proceed with caution, as using the wrong technique could dull the finish or create more scratches.
Before you begin, assess the depth of the scratch. If it is a shallow scratch that your fingernail does not catch on, you can treat it with light abrasives such as toothpaste or baking soda. If toothpaste or baking soda does not work, move on to wet sandpaper. If your nail does catch on the scratch, it is deeper and will require a series of passes with super-fine grit wet sandpaper.
When using sandpaper, always sand in a gentle, circular motion, ensuring you do not apply too much pressure to avoid creating new scratches. Start with a lower grit sandpaper, such as 800-grit, and gradually move up to a finer grit, such as 1000-grit or 1200-grit, until the scratch has completely disappeared. Sanding the plastic will level out the surface and allow products to stick and absorb better.
Once you have removed the scratch, clean the surface with a damp cloth. You may notice that the plastic has lost its lustre, so you can apply a small amount of plastic or metal polishing compound in circular motions to restore its shine. Finish by polishing the area, along with the rest of the surface, so that it blends in and looks as good as new.

Apply a plastic conditioner to neutralise yellowing or fading
To restore the colour of yellowing or fading plastic on your bicycle, you can apply a plastic conditioner. This is a simple process, but it does require specific supplies and a bit of time.
Firstly, clean the plastic pieces from any dust or debris. This will ensure that the conditioner can properly absorb into the plastic surface. Next, apply the plastic conditioner to the bicycle's plastic components. Make sure to cover the entire surface evenly. Follow the specific instructions provided with your chosen product for the best results. Some products may require you to leave the conditioner on for a specific duration or to buff the surface after application.
There are various plastic restoration products available, including those designed for automotive use, which can be found at automotive stores and general retailers. These products are formulated to neutralise yellowing and fading, restoring the plastic to its original colour.
It is important to note that not all plastic restoration products are created equal. Some may require additional preparation, such as sanding the plastic surface, to ensure the product adheres and absorbs effectively. Always read the instructions and take the necessary precautions when working with any chemicals or restoration products.
By following these steps and applying a suitable plastic conditioner, you can effectively neutralise yellowing or fading on your bicycle's plastic components, restoring them to their original colour and shine.

Use a utility blade to scrape away oxidation
Restoring the colour of bicycle plastic can be a satisfying task, and one method to achieve this is by using a utility blade to scrape away oxidation. This method is a straightforward and effective approach to removing the discoloured layer of plastic.
When using a utility blade, it is important to exercise caution and control to avoid damaging the underlying plastic or causing injury. Start by assessing the extent of oxidation on the bicycle plastic. Identify the areas that require attention and determine whether the oxidation is limited to the surface or has penetrated deeper into the plastic. This initial assessment will help guide the scraping technique and ensure a more precise and controlled process.
Holding the blade at a low angle to the surface, begin scraping away the oxidised layer with gentle yet firm strokes. It is crucial to maintain a consistent angle to avoid digging into the plastic. Apply light pressure and gradually increase it as needed, being careful not to gouge the surface. Work in the direction of the oxidation, following its grain, to efficiently lift and remove the discoloured material. Take your time and work in small sections to ensure a thorough and precise scraping process.
In some cases, the oxidation may be more severe or deeply embedded in the plastic. In such situations, it is beneficial to soften the oxidised layer before scraping. This can be achieved by applying heat carefully with a heat gun or hair dryer. Alternatively, chemical solvents can be used to soften the oxidation; however, it is essential to select a solvent that is safe for use on plastic and to follow the necessary safety precautions. Always test on a small area first to ensure the solvent does not damage the plastic.
Once the oxidation has been adequately softened, resume the scraping process with the utility blade. The softened layer will be more pliable, allowing for easier removal. Maintain a gentle touch to avoid damaging the underlying plastic, especially when working on detailed or curved sections of the bicycle plastic. By carefully scraping away the oxidation, you will gradually reveal the original colour of the plastic, restoring its aesthetic appeal.
By following these steps and employing a utility blade to scrape away oxidation, you can effectively restore the colour of bicycle plastic. This method offers a practical solution for revitalising faded plastic surfaces and can be a rewarding process for bicycle enthusiasts and DIYers alike.

Apply a coating to extend the life of the plastic
Restoring the colour of your bicycle's plastic parts can be a simple process that doesn't require spending a lot on tools or replacement parts. One way to restore the colour is by applying a coating to the plastic to extend its life. Here are some tips and instructions for applying a coating to your bicycle's plastic parts:
- Choose the Right Product: Select a suitable coating product designed for restoring plastic. Some products, like Plastic Renew, require sanding before application, while others may not. Consider the level of preparation required and choose a product that best suits your needs.
- Prepare the Plastic Surface: Ensure the plastic surface is clean and free of dirt and grime. Wash the plastic parts with soapy water and rinse them thoroughly. If there are scratches, you may need to sand them out before proceeding. Fine-grit sandpaper can help smooth out the scratches and create a uniform surface for the coating to adhere to.
- Apply the Coating: Follow the instructions on the chosen product for application. Typically, you'll work the coating into the plastic surface using a cotton rag in a circular motion. Allow the coating to absorb into the plastic, restoring its colour and shine.
- Drying and Curing: Allow sufficient time for the coating to dry and cure. Depending on the product, it may take a few hours or even longer. Refer to the product instructions for specific drying times and recommendations.
- Buffing: Once the coating has dried, you may want to buff the plastic surface to enhance the shine. Buffing can be done using a clean, soft cloth or a buffing wheel, creating a smooth and glossy finish.
- Maintenance: To extend the life of the plastic and maintain its restored colour, consider applying the coating periodically. Regular maintenance will help protect the plastic from the sun's ultraviolet rays, which can cause fading over time.
Remember to wear appropriate protective gear, such as gloves and a respirator, when working with chemicals and during the application process. Always refer to the specific instructions and safety guidelines provided by the manufacturer of the coating product you choose.
