Siding, machinery, boats, blinds, appliances, cans, paints, pots and pans, gutters…the list is endless. Many aluminum items grow dull with a layer of aluminum oxide. It doesn’t harm aluminum, it protects it. Even if aluminum is common and the aluminum oxide isn’t harmful, clean metal is nice to look at, and if you follow the directions in this article you won’t damage the metal at all.

How to Clean Metal Safely

There are scads of metal polishes and metal cleaners on the market. Go to the chemical aisle of any grocery store and you’ll find a handful of brands. They work well. In almost every case they will do their job as advertised. But I won’t use most of them. Neither would any of the other writers for How to Clean Things, and not just because we are frugal and handy. Many of the companies will not disclose their ingredients – it’s proprietary and all that. A company’s rights will trump an individual’s “right to know” in our profit-driven society. That is why do-it-yourself cleaning is the right approach for cleaning metal. That way, at least you know what you’re working with. If you’d rather buy than make your metal cleaner, well, we’ve researched a few products for each metal. These commercial metal cleaning products can be found in the right sidebar of each page. Enjoy.
