Plastic is a versatile material used in a variety of applications, from car interiors to outdoor furniture. However, it is susceptible to degradation from prolonged sun exposure, resulting in a dull or discoloured appearance. Additionally, plastic surfaces can become scratched, cloudy, or faded over time, requiring renewal to restore their original finish. The renewal process involves several steps, including cleaning the surface, assessing the severity of scratches or sun damage, and applying suitable restoration products like polishing compounds, heat treatment, or protective coatings. With proper care and maintenance, plastic surfaces can be renewed and protected from further deterioration.

Removing scratches
For light scratches, a gentle abrasive like toothpaste or baking soda can be used. Toothpaste contains silica, which helps remove stains from teeth, and can be used to remove scratches from black plastic or any other item with superficial surface scratches. Simply apply a non-gel toothpaste to the scratched area and, using a dry cotton cloth, work in small circles to buff away the scratches. Rinse the area frequently with warm water and repeat the process until the scratch is gone.
Baking soda can be used in a similar way for slightly deeper scratches that don't disappear with toothpaste. Create a baking soda paste and buff out the scratches.
For deeper scratches, micro-grit sandpaper is the easiest option. Dampen the sandpaper to prevent further damage to the item and carefully polish out the scratches.
For clear plastic, a plastic polishing compound is the best option for removing scratches. Make sure to rinse periodically during the process to observe your progress and avoid over-buffing.
After removing scratches, WD-40 can be applied to the plastic item and buffed with a cotton rag to add shine. If the plastic is intended for eating off of, olive or coconut oil can be used instead of WD-40.

Restoring colour
The sun is the biggest enemy of plastic, with ultraviolet (UV) rays slowly drying out the oils in plastic and damaging the material at a molecular level. This makes it difficult to restore a now-damaged piece of trim, as the oil dries out, dehydrates, and loses its colour. Other environmental factors, such as excessive dirt and salt laid down to combat snow, can also cause discolouration.
To restore the colour of plastic, you must first assess the extent of the damage. Clean the plastic surface to remove dirt, debris, and any residues. If the plastic has developed a cloudy look, add half a cup of distilled white vinegar per gallon of warm, soapy water to help restore the original finish.
For light scratches, use a gentle abrasive like toothpaste or baking soda. Toothpaste contains silica, which helps remove stains. Use a non-gel formula and squeeze out enough to cover the scratched area. Using a dry cotton cloth, work in small circles to buff away the scratches. Rinse the area frequently with warm water and check the scratches. You may need to repeat the process several times.
For deeper scratches, use wet micro-grit sandpaper. Always remove scratches when they are small, as accumulated or deeper scratches will be more difficult or impossible to remove. After removing scratches, apply WD-40 to your plastic item and buff it to a shine using a cotton rag. If you plan on eating off the plastic, try olive or coconut oil instead of WD-40.
Sun-faded plastic can be restored by applying even heat with a heat gun. This will bring the oils stored inside to the surface and revive the plastic's shine. You can also use a plastic restorer compound to bring life back to the surface.

Preventing sun damage
Sunlight damage to plastic is a significant problem, affecting plastic products' quality, performance, and durability. The sun, more specifically, ultraviolet rays or UV, is the biggest enemy of plastic. These rays slowly dry out the oils in the plastic and damage the material at a molecular level, making it difficult to restore. The oil dries out, loses its colour, and the plastic becomes brittle and prone to cracking.
There are several effective measures that can be taken to prevent sunlight damage to plastic. One of the most effective methods is to limit the amount of direct sunlight exposure the plastic receives. This can be done by placing the plastic in a sheltered area, using a protective cover, or coating the plastic with a protective film or coating designed to reflect UV and IR radiation.
Another option is to use a plastic restorer compound to bring life back to the surface. WD-40, for example, can be used on plastic to restore fading. It can be sprayed onto the plastic and rubbed in with a clean, dry cloth. However, it should be noted that WD-40 should not be used on polycarbonate and clear polystyrene plastic.
Additionally, using plastic additives is another way to reduce the effects of sunlight damage. These additives are specially formulated to be added to the plastic during the manufacturing process to improve the plastic's ability to withstand UV and IR radiation.
Finally, some types of plastic are naturally more resistant to sunlight damage, such as acrylic, polycarbonate, and ABS plastics. These plastics are better able to withstand direct sunlight and are less likely to become brittle or break over time.

Using polishing kits
When it comes to renewing a plastic surface, polishing kits offer a straightforward solution. These kits are designed to restore and repair faded, scratched, or dulled plastic, bringing items like trophies, CDs, antiques, and display signs back to life. Before using any polishing kit, it is essential to assess whether your plastic item is suitable for polishing. Some plastics have a thin film coating that may be damaged by abrasive chemicals in the polish. Therefore, always ensure that the plastic is cool to the touch before starting the process.
One popular option is the NOVUS Plastic Polish 3-step system. This kit is designed to address scratches, haze, and abrasions on plastic and acrylic materials. The first step is to clean the surface thoroughly using a product like NOVUS No. 1 Clean & Shine, which gently cleans plastics without leaving scratches. It is important to remove any dust, dirt, or debris before proceeding to the next steps.
The second step involves applying a scratch remover, such as NOVUS No. 2 Fine Scratch Remover, to eliminate fine scratches, haziness, and light abrasions. If deeper scratches are present, you may need to use a product like NOVUS No. 3 Heavy Scratch Remover, which is designed for more severe damage. Apply the product liberally and use a clean, soft cloth to polish the surface with firm, back-and-forth motions at right angles to the scratches. Reapply the product uniformly in a circular motion using light pressure.
For heavy scratches, multiple applications of the scratch remover may be necessary. After addressing the scratches, it is important to buff the surface to a slippery glaze using firm, short strokes with a clean cloth. Finally, you can use a product like NOVUS No. 1 polish to restore shine and protect the surface. It is recommended to test these products in an inconspicuous area before applying them to the entire surface.
In addition to commercial kits, there are also household items that can be used for polishing plastic. For example, toothpaste can be effective for shallow scratches, and baking soda mixed with water can be used as an alternative method. Wet sanding with sandpaper can be useful for deeper scratches, as it slowly evens out the plastic's surface. Always ensure to work in a well-ventilated area and wear personal protective equipment when using polishing compounds and power tools.

Cleaning plastic
Plastic is a versatile material found in many household items, from kitchenware to furniture. It is durable and designed to withstand dirt and heavy usage, but it is not indestructible and can degrade over time, especially when exposed to the sun. Here are some tips to keep your plastic items clean and well-maintained:
General Cleaning
To clean plastic items, it is recommended to use a mild dish detergent or soap with warm water and a soft sponge or microfiber cloth. For heavily soiled areas, a baking soda paste can be applied first, followed by a gentle scrub with a soft-bristled brush. Rinse the item with clean water and dry it with a towel. If using a dishwasher, place plastic items on the top rack, ensuring that the dirtiest side faces the water spray. Avoid overcrowding the racks to allow for proper water spray and air circulation.
Removing Scratches
For light scratches, a non-gel toothpaste or a baking soda paste can be used. Apply the paste to the scratched area and use a dry cotton cloth to buff it out in small circles. Rinse the area frequently with warm water and repeat the process if necessary. For deeper scratches, wet micro-grit sandpaper can be used carefully to avoid further damage. After removing scratches, apply a small amount of WD-40 or olive oil to restore shine.
Restoring Faded Plastic
Plastic surfaces exposed to sunlight may become sun-faded and dull. To restore the colour and shine, you can use a plastic restorer product or WD-40 Silicone Lubricant, which is safe for use on plastic. Spray the product onto the surface and rub it in with a clean, dry cloth. For sun-faded car interiors, a heat gun can be used to apply even heat, bringing the oils back to the surface and reviving the shine.
Removing Odours and Disinfecting
To remove unpleasant odours from plastic items, you can use natural deodorizers like lemon or orange zest. Place the zest inside the container and seal it for 10-15 minutes before washing it out. For disinfecting, a solution of vinegar and water can be used. Spray the solution onto the plastic surface, scrub built-up grime, and then rinse with clean water.
