How to Get Rid of Rust in the Sink Drain

The strategy for getting rid of rust in a sink drain should depend on what substance the rust is on: porcelain or metal.

Porcelain Sink

Fortunately, porcelain is harder than a pumice stone, and pumice stones are harder than rust. Therefore, they are an excellent tool for removing rust on porcelain. Many people suggest using steel wool to remove rust from metal, but if you want to make sure not to scratch the surface, a simple non-metallic scrub pad may suffice. Barring that, the acid in Coke works wonders if you can keep the rust wet long enough.

Purchase a pumice stone in the cosmetics section of a drugstore.

Moisten the end of the pumice stone.

Rub it against the rust, like you were erasing it with a pencil eraser. The rust will come right off.

Metal Sink

Rub the rust roughly with a moistened scrub pad. That alone may be enough to get the stain out safely without scratching your surface. If not, go on to the next step.

Dry the sink drain.

Moisten a few paper towels with Coca-Cola.

Layer them on top of the rust stain and leave them overnight.

Wipe what remains of the stain the next morning with a dry paper towel.
