Aluminum is one of those metals that oxidize, that is, they react with the oxygen in the air. Aluminum forms on its surface a layer of aluminum oxide, also called alumina, of black color. This reaction is slower than the formation of rust on iron, which is why when one decides to clean blackened aluminum, the layer is generally quite thin or consists of only a few scattered black spots. The alumina protects the metal but it is not satisfactory from an aesthetic point of view. This is why cleaning aluminum is an eternal restart, unless it is covered with a protective layer. Here are some tips for cleaning aluminum and making it shine.

If you are still not satisfied, you will place some coarse salt on the surface to complete the cleaning with a light abrasive action. Be careful not to scratch the surface!
Clean aluminum with white vinegar
