How to Polish Aluminum Wheels to a Mirror Finish: A 5-Step Guide

Want to restore dull aluminum wheels without leaving swirl marks? Start by checking the finish. This process is for bare aluminum or wheels being refinished; painted, clear-coated, and diamond-cut wheels need different treatment.

1. Clean and inspect.

Remove brake dust and grease. Check for cracks, bends, or deep curb damage: polishing only improves the surface.

2. Prepare the metal.

If refinishing, remove damaged coating by a suitable method. Sand through progressively finer grits, removing each previous scratch pattern. Weike coated abrasives can help prepare the surface; use smaller tools around spokes.

3. Cut the haze.

Pair a firm stitched cotton buffing wheel with a cutting compound suitable for aluminum. Make light, overlapping passes and keep the wheel moving to control heat. Avoid aggressive sisal on delicate wheel faces.

4. Finish the shine.

Change to a clean, soft cotton or airway buffing wheel with a fine finishing compound. Keep cutting and finishing wheels separate to prevent coarse residue from scratching the finish.

5. Protect the result.

Remove compound residue, inspect under bright light, and apply a suitable protective finish. Bare polished aluminum needs regular care to stay bright.
