Clean with mild soap, pH-balanced cleaners, or diluted bleach
To keep your plastic items looking new, regular cleaning with mild soap, pH-balanced cleaners, or diluted bleach is essential. Dust, dirt, and air pollutants can slowly degrade plastic over time, so it is important to clean plastic surfaces gently yet thoroughly. Avoid harsh chemicals like undiluted bleach, as these can weaken plastic fibres, discolour surfaces, and cause cracking, especially on soft plastics.
When using bleach, always dilute it according to the instructions and wear gloves. You can mix diluted bleach with detergent, a household cleaner, and water, and then spray this solution onto discoloured areas of plastic. Alternatively, you can use a mild soap solution and a soft cloth or sponge to wipe down plastic surfaces gently. Ensure you dry the surfaces thoroughly after cleaning to prevent water spots or mineral buildup.
For more intensive cleaning, you can use sandpaper dipped in soapy water to scrub hard plastic. This method effectively removes dirt and oxidation, which can cause discolouration and a rough texture. If you are dealing with vinyl plastic, a mixture of vinegar and water can be sprayed onto faded areas.
In addition to cleaning, it is important to protect your plastic items from sun exposure, as UV rays are the main cause of colour fading and material breakdown. Store plastic items away from direct sunlight, and consider using a UV sealant to protect them further. By combining gentle cleaning techniques with shaded storage, you can effectively maintain the appearance of your plastic items and keep them looking new.

Dry thoroughly to prevent water spots
To keep plastic looking new, it's important to dry it thoroughly to prevent water spots and mineral buildup. This is because dust, dirt, and air pollutants can slowly degrade plastic over time. Here are some tips to ensure your plastic items are dried properly:
Firstly, after cleaning your plastic items with mild soap or pH-balanced cleaners, rinse them well to remove any soap residue. Then, use a soft, clean cloth or towel to wipe down the surfaces. Ensure you dry all surfaces, including any crevices or hard-to-reach areas. You can also use a hairdryer on a low setting to speed up the drying process, but keep a safe distance from the plastic to avoid potential melting or warping.
If your plastic item is outdoors or exposed to the elements, such as garden furniture or car interiors, it's crucial to dry them thoroughly after cleaning. Use a microfiber cloth to absorb any standing water, and consider using a mild blower to remove moisture from hard-to-reach places. Always ensure complete drying before using the item or exposing it to direct sunlight or harsh weather conditions.
In the case of vehicles, discolored plastic is often a combination of dirt and sun damage. After cleaning and drying, you can use a heat gun on its lowest setting to restore the color. Keep the heat gun moving and at least 5-10 cm away from the surface to avoid damage. Alternatively, products like tire shine or dedicated plastic restorers can be applied and left to dry, giving your plastic surfaces a refreshed appearance.
For smaller plastic items, such as toys or household objects, you can gently pat them dry with a soft cloth. If needed, you can use a hairdryer on a cool setting to assist in the drying process. Ensure that all surfaces are completely dry before use or storage.
Remember, thorough drying helps prevent water spots and maintains the integrity of your plastic items. By taking the time to dry them properly, you can keep your plastic possessions looking new for longer.

Store away from sunlight
Sun exposure is a major cause of discolouration and deterioration in plastic items. Therefore, it is important to store plastic items away from direct sunlight to keep them looking new.
UV rays from the sun cause colour fading and material breakdown, so it is essential to keep plastic items out of direct sunlight when they are not in use. This includes items such as patio chairs, garden tools, containers, and vehicles. For example, consider parking your car in a covered area or using a windshield sunshade to protect the interior plastics. Even indirect sunlight can cause fading over time, so it is important to consistently store plastic items away from sunlight.
Additionally, when storing plastic items, it is beneficial to use shaded storage solutions such as garages, sheds, or closets. If possible, cover plastic items with a shade cloth or tarp to provide an extra layer of protection from the sun's rays. By taking these precautions, you can effectively reduce the impact of UV radiation on your plastic belongings.
Furthermore, when choosing a storage location, opt for areas that remain cool and well-ventilated. High temperatures can cause warping or melting of plastic, especially when combined with direct sunlight. By maintaining a moderate temperature in the storage area, you can help preserve the integrity and appearance of your plastic items.

Use a heat gun on a low setting
Using a heat gun on plastic can be a delicate process, as applying too much heat can melt, warp, or permanently damage the plastic. To keep plastic looking new, follow these steps:
First, ensure the plastic surface is clean and free of any debris or grease. Regular cleaning with mild soap or pH-balanced cleaners can help maintain the surface integrity of the plastic and prevent UV damage. Keep plastic items away from direct sunlight, as UV rays are the main cause of colour fading and material breakdown.
Next, if your plastic item has rough edges, trim them with a sharp blade or sandpaper before applying heat. This will ensure a smooth finish.
Now, it's time to use the heat gun. Start by setting the heat gun to its lowest setting. Keep the gun moving and avoid prolonged exposure to any single spot, as this can melt or damage the plastic. Hold the heat gun at least 5-10 cm away from the surface of the plastic and move it slowly and evenly across the area you want to treat. You can gradually increase the temperature until you see the desired results, but be cautious to avoid overheating.
Once you have achieved the desired results, allow the plastic to cool and solidify completely before handling it. If your heat gun has a fan-only function, you can use it to manually cool the plastic. After the plastic has cooled, you may want to trim any excess plastic or rough edges that remain with a blade or sandpaper.
By following these steps, you can effectively use a heat gun on a low setting to restore the appearance of plastic items and extend their lifespan.

Apply hydrogen peroxide or paint as a last resort
To keep plastic looking new, you can try applying hydrogen peroxide or painting it as a last resort.
Using Hydrogen Peroxide
Before applying hydrogen peroxide, ensure the plastic is clean and dry. Use a scrub brush to clean the surface, removing any loose paint, dirt, mildew, or algae. You can also use soapy water to remove dirt and grime. If the plastic has mildew or algae, you may need to scrub harder.
Once the plastic is clean and dry, you can apply hydrogen peroxide. Wear thick rubber gloves and place the plastic item on a stable work surface with a towel underneath it. Use a paintbrush with natural bristles to apply hydrogen peroxide cream or simply pour the hydrogen peroxide directly onto the surface.
For deeper discoloration, apply a thick layer of hydrogen peroxide cream to the affected areas. Make sure to cover all discolored sections. You can also use hydrogen peroxide hair cream designed for bleaching hair, ensuring it contains 9-12% hydrogen peroxide.
After applying the hydrogen peroxide, leave it to work for a few hours. Check on it periodically to ensure that the cream has not dried out. If it has dried out, apply a fresh layer of hydrogen peroxide. Rinse the plastic thoroughly after the discoloration has disappeared.
It is important to note that hydrogen peroxide should be handled with caution. Always read the instructions and take the necessary safety precautions. For example, 35% hydrogen peroxide is extremely concentrated and must be diluted before use.
Painting Plastic
If the plastic is still discolored after trying other methods, you can consider painting it. Choose a paint specifically designed for plastic, such as Krylon Fusion for Plastic or Rust-Oleum Specialty Plastic Primer Spray. These paints are formulated to stick better to plastic surfaces and resist peeling.
Before painting, ensure the plastic surface is clean and dry. Use a scrub brush or sandpaper to roughen the surface, which will help the paint adhere better. If the surface is too glossy, the paint may not stick properly.
When painting, hold the can at an angle and lightly mist the surface from about 12 inches away. Avoid spraying from too far away, as this can result in a dusty, grainy coat. After the first coat, let the paint dry for a few hours before applying a second coat.
You can also use a brush and acrylic paint designed for plastic, but this may leave brush marks. If you only paint the affected area, the new paint may clash with the older layers. Consider painting larger sections or the entire item for a more consistent finish.
By following these steps, you can effectively use hydrogen peroxide or paint to restore discolored plastic and keep it looking new.
