The easiest way to restore faded plastic bumpers is to purchase a can or bottle of plastic trim restorer from your favorite auto parts shop or online store. Most are easy to apply and require almost zero elbow grease, although most are also pricey at about $15 to $40 per bottle. The typical instructions are to wash the plastic parts with soapy water, wipe dry, apply the product, and buff lightly. In most cases, repeated or periodic treatments are necessary to maintain that coveted like-new look.
If your plastic bumpers are severely weathered and have signs of folding, shrinking, large cracks, or deep scratches, it could be better to replace them altogether. But if you don’t want to spend big money, there are DIY solutions worth trying, but it’s essential to curb your expectations from the onset. The restoration methods listed below are great for mildly deteriorated surfaces. The steps would only take a few minutes, and most require only essential household items.
