How to: Remove scratches from piano black trim by hand

After shopping at Costco and loading the Explorer with groceries I took a closer inspection of the car’s piano black trim. To my surprise It looked like someone accidentally cleaned the trim with a scruff pad. It had so many swirls it started looking like the Starry Night painting. Look at the above picture and see how scratched it looks.

Good news is that I was able to remove majority of the scratches by hand.  I’ll show you how I accomplished it.

What I’ll be using

Step One: Clean the piano black trim. I used soapy water to clean the dirt off, then rinsed with water, and then wiped dry.

Step Two: Once the area is cleaned put some Meguiar’s M10508 Mirror Glaze Ultra-Cut Compound onto a applicator pad. Then polish the area in a circular motion if possible. I polished the area for a good 5 minutes.

Step Three: Wipe the polish away with a microfiber towel and inspect. I was happy with the result of from step two so I went onto the next step. If there’s any noticeable defects then I would have went back to the previous step.

Step Four: I then used Meguiar’s M20508 Mirror Glaze Ultra Finishing Polish to finalized the polish. I used the same circular motion when applying the polish.

Step Five: Wipe the polish away with a microfiber towel and inspect. I was really happy with the result so I finalized this step with wax.

Before and After


It no longer looked like a painting of the Starry Night. It did remove majority of the scratches and made it glossy. However upon closer inspection, there was still some deep scratches. Here’s a close up of what it looks like:

Overall, I was happy with the outcome and the scratches weren’t as noticeable compared to before. It’s possible that I could have spent more time on step two to remove the remaining scratches. But I know in the future, there will be more scratches. How to prevent future scratches? Unfortunately, there’s only so much that can be done to prevent future piano black from scratching. The best option is to put on a 3M Clear Paint Protection vinyl film to protect the trim.
