Buff aluminum to a shiny finish with jeweler's rouge.

Jeweler's rouge achieves stunningly smooth results when used to polish metals. The rouge comes in several colors, each of which represents a different grit. Powders of varying fineness make up the rouge compounds. The best color for a specific project depends on the metal, its condition and the smoothness of the sheen desired. According to jeweler's rouge manufacturer Schaffner Manufacturing Co., white "produces a clear, brilliant, mirror-like finish" on aluminum. However, you must first polish scratched aluminum with a grittier jeweler's rouge and then re-polish it with progressively finer-grit rouges until you've removed the scratches; then apply a finish polish.

Continue buffing until you have polished the entire surface.

Step 7

Repeat with a finer-grit rouge if you desire a shinier surface.

Step 8

Wash the aluminum in warm, soapy water to remove any rouge residue. Dry with a soft, scratch-free cloth.

For badly scratched aluminum, sand the scratches out with sandpaper before polishing the piece with jeweler's rouge.
