Two methods- I have used both. First, try spraying with Testors Dullcoat.

An old ham trick used on aluminum radio panels: Mix up a solution of one about a half tablespoon of draino or other lye drain cleaner in a gallon of water. Clean aluminum first with soap and water, then immerse in solution for about a minute or so. It should bubble vigorously. If left in too long, black deposits will form, but these can be rubbed off.

ModelGeeks.comhttp://www.modelgeeks.com/Uwe/Forums.aspx/models/200703/1 If you want the finish to be really durable, you could have them anodized to a clear satin finish. I had that done to all my Sherline lathe's aluminum handwheels. Looks great and no more discoloration from touching them.

A bit pricey because most commercial metal finishers have a minimum price. Mine was something like $75US.

If you don't need the durability, spray them with Testors Dullcote, Floquil flat finish or another clear flat lacquer available in various hobby or hardware stores.

Of course you might have a big mess to clean up after rubbing ham all over it.
