Rust forms when iron combines with oxygen, creating the familiar brownish-orange layer on a metal surface. When aluminum is rubbed against the rust, the aluminum loses electrons while the iron oxide gains them, turning back into metal, as per the Homes and Gardens report.The aluminum acts as a reactive surface that helps remove the rust while also forming a layer of oxide.According to cleaning experts, adding an acid such as vinegar or lemon juice can speed up the reaction, as per Homes and Gardens report. The foil can be dipped in the acid, or the item can be soaked when possible.You Might Also Like:Can You Use Aluminum Foil on Other Metal SurfacesAluminum foil can also be used to help remove rust from metals such as chrome and steel.
