Your car’s rims are not just functional; they’re a statement of style and pride. Unfortunately, over time, even the most carefully driven vehicles can fall victim to scratched and scuffed rims. The good news is that you don’t have to live with unsightly blemishes. With the right tools and techniques, you can restore your scratched rims to their former glory. In this guide, we’ll explore how to make scratched rims look new using a powerful tool—the angle grinder.


Understanding the Damage:

Before diving into the restoration process, it’s crucial to assess the extent of the damage. Surface scratches, scuffs, and minor abrasions are usually the result of day-to-day driving and can be effectively addressed with the right tools. However, deep gouges and structural damage may require professional intervention.


Materials and Tools:

  • Angle Grinder:Choose a quality angle grinder with variable speed settings and a polishing attachment. The angle grinder will be the workhorse in removing scratches and bringing back the shine.
  • Safety Gear: Prioritize safety with protective gear such as safety glasses, gloves, and a dust mask. Safety should always come first when working with power tools.
  • Sandpaper: Get a variety of sandpaper grits, ranging from coarse to fine. This will be used to progressively smooth out the scratches.
  • Polishing Compound: A high-quality polishing compound will help bring back the shine to your rims.
  • Microfiber Towels: These are essential for wiping away debris and polishing the rims.


Step-by-Step Guide:

Step 1: Safety First

Before you start any work, put on your safety gear—safety glasses, gloves, and a dust mask. Ensure that your work area is well-ventilated, and if possible, work outdoors to minimize the inhalation of dust particles.

Step 2: Clean the Rims

Start by thoroughly cleaning the rims with a mild detergent and water. This removes any dirt, brake dust, or grime that might interfere with the restoration process.

Step 3: Assess the Damage

Examine the rims closely to identify the depth and severity of the scratches. If they are superficial, an angle grinder can effectively address the issue.

SANDPAPER FOR CARStep 4: Choose the Right Sandpaper Grit

Begin with a coarse-grit sandpaper (around 80 grit) to eliminate deep scratches. As you progress, move to finer grits (e.g., 120, 240, 400 grit) to smooth out the surface. Be patient and make sure to sand evenly.

Step 5: Use the Angle Grinder

Attach a sanding disc to the angle grinder and set it to a low speed. Hold the grinder steadily, applying even pressure to the scratched areas. Move the grinder in a circular motion to avoid creating uneven surfaces. Check your progress regularly.

Step 6: Switch to Finer Grits

As you work through the sandpaper grits, you’ll notice the scratches becoming less prominent. Switch to progressively finer grits to refine the surface further. This process will prepare the rims for polishing.

Step 7: Apply Polishing Compound

Once the rims are smooth and the scratches are nearly gone, switch to a polishing attachment on the angle grinder. Apply a small amount of polishing compound to the rims and use the grinder to buff the surface. This step will bring back the shine and remove any remaining imperfections.

Step 8: Final Touches

Inspect the rims for any overlooked scratches or uneven areas. If necessary, repeat the sanding and polishing process until you achieve the desired result.

Step 9: Clean the Rims Again

After completing the restoration, clean the rims thoroughly to remove any residue from the polishing compound.

Step 10: Protect the Finish

To keep your rims looking new, consider applying a protective coating or wax. This will help guard against future scratches and make maintenance easier.



Restoring scratched rims with an angle grinder is a DIY project that can yield impressive results when done with care and precision. By following these steps and investing time and effort, you can bring back the shine to your rims and enhance the overall appearance of your vehicle. Remember, patience and attention to detail are key to achieving professional-looking results. If the scratches are too deep or extensive, it’s advisable to consult with a professional to ensure the structural integrity of the rims is not compromised. With the right tools and techniques, you can take pride in the rejuvenated appearance of your once-scratched rims.
