Some tips for aluminum polishing include cleaning the surface of the object first, buffing or sanding scratched areas of the metal and wearing appropriate safety gear. It also helps to use polishing products especially designed for aluminum.
A bit of preparation makes a big difference when polishing aluminum. Some of the tools involved in the process are power tools, so it is important to protect the skin and eyes from damage. A pair of safety goggles is essential, and a heavy pair of work gloves can help keep the hands safe from rough tools and compounds. As compounds and polishes can stain clothes, a shop apron is also a useful item to have on hand.
When polishing any metal, make sure the item is clean before getting started. Oil and dirt can work its way into the metal while buffing, so it is important to clear it away.
Scratched or rough surfaces can reduce the shine of the aluminum, so it is important to sand out any marks during the polishing process. Ideally, sand out rough patches and scratches with a buffer and an abrasive compound. A buff kit usually includes all of these materials. If these tools are not available, some wet/dry sandpaper can do the trick; however, it can be tricky to sand down large areas of metal with sandpaper.
If the piece has a lot of grooves or texture, use a brush to remove leftover compound from grooves and other hard-to-reach areas after buffing.
To make the aluminum shiny again, finish off the process with a metal polish designed for aluminum. Helpful products include Mothers Billet Polish and Eagle One Nano-Polish.
