Removing rust from vintage metal stools is a simple process that can be achieved using items you already have in your home, including white vinegar and aluminum foil.
Using natural products such as distilled white vinegar reduces the risk of damaging the underlying metal frame on your vintage piece, while aluminum is less abrasive than other products such as steel wool which are typically used for cleaning away rust.
To clean your stool, fill a spray bottle with white vinegar and completely cover the stool’s rusted area. Allow it to soak for 30 minutes, then take a piece of aluminum foil and scrunch into a ball, dip it in more vinegar and gently scrub at the rust in small circular motions.
If you have a significant rust problem, use a commercial cleaner made using oxalic acid and follow the manufacturer’s instructions.
