Plastic bumpers are prone to fading, discolouration, cracking, and deterioration over time due to exposure to sunlight and harsh weather conditions. This can make your vehicle look old and neglected. Fortunately, there are several methods to rejuvenate faded plastic bumpers and restore them to their former glory. This includes using dedicated plastic restoration products, applying heat guns or olive oil, and painting. It is also important to protect the bumpers from future damage with sealants or protectants.

What You'll Learn
Clean with soap and water
If your car's plastic bumpers are looking a little worse for wear, a good clean with soap and water can be a great first step to rejuvenate them. This method is especially useful if your bumpers are only mildly deteriorated, with some surface grime, dust, and dirt.
First, grab a bucket of warm water and add some car soap. You can also use regular soap, but car soap is designed to remove dirt and grime from your car's exterior and is less likely to cause damage or discolouration. Dip a soft cloth or sponge into the soapy water and start scrubbing your bumpers. If you're dealing with stubborn dirt or grime, you might need to use a soft-bristled brush, like a toothbrush, to really get into the grooves of the plastic.
Rinse the bumpers with clean water to remove any remaining soap and dirt. If needed, you can repeat the process until your bumpers are looking clean. Once you're happy, grab a microfiber towel and dry the bumpers thoroughly. This step is important, especially if you plan to apply any products after cleaning. A dry surface will ensure that any oils, moisturizers, or restorers you apply will absorb properly.
While soap and water are great for a general clean, it might not be enough to remove paint transfer or more stubborn marks. In these cases, you may need to use a lacquer thinner to remove the marks, repeating the process until they're gone. You can also try a vinyl cleaner on a rag to wipe down the bumpers, followed by a soft brush to remove any remaining gunk.
Remember, if your bumpers are severely weathered, with large cracks or deep scratches, a simple soap and water clean might not be enough. In these cases, you may need to explore other rejuvenation methods, such as using a plastic trim restorer or even replacing the bumpers altogether.

Use a plastic restorer
Using a plastic restorer is an easy and cost-effective way to rejuvenate a plastic bumper. You can purchase a plastic restorer from an auto parts shop or online store. The typical instructions for application are as follows:
First, wash the plastic bumper with soapy water to remove surface grime, dust, and dirt. You can also use isopropyl alcohol for this step to ensure there is no residue, only bare plastic. Rinse well with clean water and wipe dry with a microfiber towel.
Next, apply the plastic restorer. You can use a microfiber applicator or foam applicator to do this. Wipe off any excess product with a clean towel. Allow the plastic to dry for around 6 hours.
After the first application, your plastic bumper should stay black and look new for approximately 8 months or more. You can then apply a second coat, which will last even longer.
It is important to note that some sources advise against using a plastic restorer as it can damage the plastic. Torching or using a heat gun on the plastic will eventually turn it grey and dull again, and repeated applications can further damage the plastic.
Another option is to use a black plastic trim moisturizer, which can be purchased from most automotive stores. These products restore car trims and bumpers by adding moisture to their surface. You can also use olive oil, which can restore black plastic's natural colour and clear up any faded or discoloured areas.

Try olive oil
If your car's plastic bumpers are looking a little worse for wear, you might be wondering what you can do to rejuvenate them. One option is to try olive oil.
Cleaning the Bumper
First, you'll want to clean the bumper thoroughly. Use warm soapy water to remove any dirt, dust, and grime. Rinse the bumper with clean water and then dry it off with a microfiber towel. It's important to ensure the bumper is completely dry before moving on to the next step.
Applying the Olive Oil
Pour a coin-sized amount of olive oil (extra virgin is best) onto a clean, dry microfiber cloth. You can also use a paper towel or a washcloth. Gently rub the oil onto the faded plastic using small circular motions. If the cloth becomes dirty, turn it over, add more oil, and continue rubbing until all faded areas are covered. Remember, a little olive oil goes a long way, so you don't need to use too much at once.
Letting the Oil Absorb
Allow the plastic to absorb the olive oil. Let it soak for about 5 to 10 minutes. The olive oil will help restore the plastic's natural colour, bringing back its original shine.
Buffing the Surface
After the oil has had a chance to absorb, grab a separate, dry microfiber towel. Buff the surface lightly using rapid circular motions. Turn the towel over and give it a final buff to ensure an even finish.
Maintaining the Results
Keep in mind that the results of using olive oil on plastic bumpers are not permanent. The shiny, black finish will eventually fade after repeated washings or exposure to weather. To maintain the rejuvenated look, reapply olive oil at least once a week. This will not only keep your bumpers looking new but will also provide protection from harsh UV rays.

Apply heat
If you are looking to rejuvenate a plastic bumper, one method is to apply heat. This can be done using a heat gun, which can be purchased at an auto body supplier or hardware store. Before applying heat, it is important to clean and dry the plastic bumper to avoid burning in any dirt or stains. Cover nearby non-plastic objects with a tarp, as heat guns can warp or discolour non-plastic surfaces.
When using a heat gun, it is important to hold it several inches away from the surface and move it in small circles to avoid burning the plastic. The heat from the gun will make the plastic pliable, allowing it to be reformed and reducing the risk of cracking. It is important not to heat the plastic too much, as this can make it untouchably hot and more brittle, increasing the chances of it cracking or breaking.
The heat from the gun will also bring the oils in the plastic to the surface, which can restore its colour and shine. However, this is a temporary solution, as the plastic will eventually fade again. Each time heat is applied, the plastic becomes more brittle, so it is recommended to use a rejuvenation product instead of heat treatment.
After applying heat, you can follow up with a plastic trim restorer or polish to maintain the restored colour. You can also use olive oil or a black plastic moisturiser, which can be applied in the same way as olive oil, to restore the colour and add moisture to the surface.

Seal with a protectant
After restoring the plastic trim and bumpers, it is important to protect them from future damage. You can do this by applying a dedicated plastic protectant or sealant. These products provide a layer of defence against harmful UV rays, environmental contaminants, and moisture.
There are various products available to protect your plastic trim and bumpers. You can use a dedicated plastic sealant or protectant, which will help prevent fading, cracking, and discolouration. These products create a barrier that keeps your trim and bumpers looking pristine for longer. You can also use a plastic restoration compound or polish, which contain abrasive particles that help remove surface imperfections and restore clarity to the plastic.
Regular maintenance is key to preserving the results of your restoration efforts. Routinely clean the trim and bumpers with a mild automotive detergent and protectant-safe microfiber towels to remove dirt and grime. Avoid using harsh chemicals or abrasive tools that could damage the restored surfaces.
If you are looking for a more natural solution, olive oil can be used to restore black plastic's natural colour, clearing up any faded or discoloured areas. You can also use black plastic moisturizers, which restore car trims and bumpers by adding moisture to their surface.
It is important to note that some protection methods are more effective than others. For example, using a heat gun can offer a temporary fix, but it may make the plastic more brittle. Similarly, using a silicone-based product will initially look great, but it will speed up the fading process in the long term.
