Sun exposure can cause plastic to crack and lose its colour. To restore a sun-faded plastic slide, you can try using a heat gun, sandpaper, hydrogen peroxide, or wax. Heat guns can be used to melt away the discoloured layer of plastic. This method should be practised on a small area first, as it may not be suitable for all types of plastic. Sandpaper can be used to remove oxidation, which causes plastic to wear down and become rough. For hard plastics, sandpaper can be dipped in soapy water and rubbed in a circular motion. For softer plastics, a mixture of detergent, household cleaner, water, and bleach can be sprayed on the area. Hydrogen peroxide can be used to reverse discolouration in white, grey, or yellow plastic. The cream variety is easier to spread and can be painted on with a brush. Finally, wax paper can be used to create a smooth surface on the slide.

What You'll Learn
Use hydrogen peroxide to reverse sun damage
Sun-damaged plastic can be restored using hydrogen peroxide. This method is especially useful for reversing discolouration in white or grey plastic products that have turned yellow due to bromine in the plastic.
To restore sun-damaged plastic using hydrogen peroxide, follow these steps:
- Clean the plastic surface thoroughly with rubbing alcohol or another cleaner to remove dirt that may cause streaking and spots.
- Tape off or cover any coloured areas with clear tape or masking tape to protect them from the hydrogen peroxide.
- Use a 12% hydrogen peroxide cream instead of the liquid variety. Brush an even layer of the cream over the discoloured area using a paintbrush, foam brush, or an old toothbrush.
- Seal the plastic item in a clear plastic bag to prevent the cream from drying out. Tie the opening shut or use a zippered storage bag.
- Place the bagged item outdoors in direct sunlight. Avoid placing it on a hot surface, such as asphalt.
- Rotate the bag every hour or so for about four hours, ensuring that the sunlight hits the discoloured area evenly.
- Rinse off the cream with a damp rag before it dries.
- If necessary, repeat the process, adding more hydrogen peroxide, bagging the item, and placing it in the sun again.
- Finally, wash the plastic with soap and water, and dry it with a microfiber cloth.
It is important to note that hydrogen peroxide will damage most metals, so be sure to remove any metal trim from the plastic item before beginning the restoration process. Additionally, avoid letting the cream dry up, especially under the hot sun, as it can cause an irreversible ugly bleaching effect.
As an alternative to sunlight, you can expose the hydrogen peroxide-coated plastic to ultraviolet (UV) light using a UV lamp or LED UV light source. This method provides more control over the intensity and duration of UV exposure, reducing the risk of melting or distorting the plastic.

Treat with commercial plastic conditioning products
To restore a sun-faded plastic slide, one can use commercial plastic conditioning products. Firstly, wash and dry the slide. Dampen a microfiber cloth in lukewarm water and use it to wipe down the slide, removing any dirt, dust, or debris. Dry the slide fully with a clean microfiber cloth. Next, apply a plastic conditioning product. Squeeze out about a coin-sized amount of the product onto the slide. Using a clean, soft microfiber cloth, wipe the cloth in a circular motion until the conditioner is no longer visible on the slide. Finally, wipe off any excess conditioner and let the slide dry.
If the conditioner pools and has no effect, repeated applications will likely not restore the plastic. Instead, use a plastic buffing product if there are any scratches. Look carefully at the slide, as sun damage can leave behind cracks. Place a coin-sized amount of the buffing product on a cloth rag and buff out the scratch using circular motions. Always wipe using circular motions and avoid scrubbing, as this will wear down the plastic. Wipe off the buffing product with a microfiber cloth.
There are also other ways to prevent plastic from sun damage. One way is to apply a UV-resistant sealant. Products like Graphene VRT or 303 Aerospace Protectant form a protective barrier that blocks ultraviolet rays and helps lock in color and moisture. Apply the sealant with a microfiber cloth on clean, dry surfaces. Reapply every few months, depending on exposure and product instructions.

Buff out scratches with a plastic buffing product
If you notice any scratches on the plastic slide, you can use a plastic buffing product to restore its appearance. Firstly, carefully inspect the slide for any sun damage, as this can cause unsightly cracks in the plastic.
To begin the buffing process, place a coin-sized amount of the plastic buffing product onto a cloth rag. Then, using circular motions, buff out the scratches. It is important to always wipe using these circular motions and avoid scrubbing, as this can wear down the plastic.
Buffing products come in varying strengths, so choose one that is suitable for the depth of the scratches. If the scratches are light, a product designed for shallow marks will be sufficient. For deeper scratches, you will need a stronger product.
Once you have finished buffing, wipe away any remaining product with a microfiber cloth. Ensure that you remove all of the buffing compounds before continuing to the next step, as any leftover product could further abrade the slide.
If there are still some visible scratches, you may need to repeat the buffing process or try using a finer-grit sandpaper to smooth out the scratches. Additionally, you can apply a small amount of plastic polishing compound to restore the shine to the slide.

Use sandpaper to restore hard plastic
To restore sun-faded plastic, you can use a heat gun, hydrogen peroxide, or sandpaper. While the heat gun method is popular, it can be risky as it involves melting the surface of the plastic. If done incorrectly, it can cause further damage. Similarly, hydrogen peroxide can be effective, but it is only suitable for white or grey plastic.
Using sandpaper is a good option for restoring hard plastic. Here is a step-by-step guide:
First, ensure your plastic is clean. Wash it with warm soapy water and towel dry. Next, fill a bucket with soap and water. Dip 150-grit sandpaper into the soapy water and rub the surface of the plastic in a circular motion. Cover each faded area 5-6 times. Then, use a sheet of 220-grit sandpaper and repeat the process. Again, cover each section 5-6 times. Finally, rinse the surface.
It is important to use the correct type of sandpaper and technique to avoid damaging the plastic. Coarse-grit sandpaper is best for removing heavy imperfections, such as deep scratches, but it can be too aggressive and cause deep gouges if not used carefully. Finer-grit sandpaper is better for smoothing out the surface and removing scratches. Silicon carbide sandpaper is recommended for plastic as it cuts efficiently without excessive friction or clogging.
If there are still scratches after using sandpaper, you can use a plastic buffing product. Place a coin-sized amount on a cloth rag and buff the scratch using circular motions. Always wipe off the product with a microfiber cloth afterward.
Practising on an old piece of plastic first is a good way to get a feel for the process and avoid damaging the slide.

Repaint the slide
If your plastic slide has lost its colour due to sun damage, you can repaint it to restore its appearance. Before you begin, ensure you are wearing protective gear, such as thick rubber gloves and goggles, to safeguard yourself from any harmful chemicals.
Firstly, clean the slide thoroughly to remove any dirt, dust, or debris. Use a damp microfiber cloth to wipe down the slide, and then dry it completely with a clean cloth. For tough stains, you can use a mixture of liquid laundry detergent and warm water. Alternatively, scrub the slide with sandpaper dipped in soapy water to remove any stubborn dirt or discolouration.
Once the slide is clean and dry, you can apply a primer or a commercial plastic conditioner to prepare the surface for painting. This step will help the new paint adhere better to the plastic and create a more even finish. Follow the instructions on your chosen product for the best results.
When the primer or conditioner is dry, it's time to select the right paint for the job. Choose a paint that is specifically designed for use on plastic surfaces. You can find these paints at most hardware stores or online. Make sure to select a colour that matches the original slide colour or your desired new colour.
Before you begin painting, it is recommended to practice your technique on an inconspicuous area of the slide or on a similar piece of plastic. This will help you get a feel for the paint and ensure that you are happy with the colour and finish.
Now, you can start painting the slide. Use a paintbrush, foam brush, or spray paint designed for use on plastic surfaces. Work in small sections, following the direction of the slide's curves, and avoid overloading your brush to prevent drips. Allow each section to dry completely before moving on to the next, following the instructions on your paint for drying times.
Finally, once the paint is dry, apply a clear sealant to protect the new paint job and add a layer of shine. This sealant will help extend the life of your slide by creating a barrier against the elements.
Remember to follow all safety precautions when working with chemicals and paints, and ensure the slide is completely dry and safe before allowing anyone to use it.
