Beside this, does vinegar clean aluminum?

Aluminium doesn't get clean with any alkaline-based substance such as laundry powder. Use acid-based substances such as citrus juice or white vinegar (basically, any mild acid). Scrub hard with or boil in a vinegar or lemon juice solution.

Likewise, does vinegar etch steel? Lemon juice is citric acid, and vinegar is acetic acid (Ketchup and mustard have vinegar in them). Vinegar works best when warmed to about 100°F and allowed a long soak. It will not noticeably affect stainless steel. Plain white vinegar is what you want, but any vinegar will work.

In this way, can you etch aluminum?
