Intact metal
Metal rust is common. Metals oxidize due to their low ionization, and yes, I am implementing terms that I studied in my chemistry class, but it’s just so interesting I can’t help it. Anyways, a good way to get rid of the rust is using aluminum foil.
Take a sheet of aluminum foil and fold it into a small ball. Then rub it on the rusted surfaces with a little vinegar. Aluminum and vinegar make a perfect combination. There is not much science behind this trick. Try it!
