How to Remove Rust on a Bicycle

Put some metal polish on the brass or bronze wool.

Rub the wool over the rusted spot, moving it back and forth until the rust starts scraping off. Do not move the wool in a circular motion, as this will scratch your bike. Instead, move the wool back and forth or up and down. Make small, conservative movements. Be careful not to rub the spot after the rust is gone, as this will also scratch your bike.

Repeat this process on all rust spots until they are gone.

Finish by using a rag or an old t-shirt to polish your bike until it looks nice and shiny.

Grab a medium-sized piece of foil (about the size of a piece of printer paper). Create a loose ball with the foil, leaving room for air pockets.

Rub the foil over the rust. Rub lightly at first, applying more pressure until the rust starts to come off. Be careful not to rub too hard or you might get scratches on the chrome.

Repeat until the rust is gone.

Wipe down your bike with a wet rag and let it dry.

Squeeze lime juice onto the steel wool. Rub the wool onto the rust until it disappears. Do not use a circular pattern when rubbing, but rather use an up and down or a left and right pattern.

Rinse the lime juice with water. You don't want to leave the citric acid on your bike, because this will corrode the metal.

Thoroughly dry with a paper towel, checking to make sure you've got all of the water and citric acid off of your bike. Leaving either one behind can harm your bike.
