Things You'll Need
1/2 cup baking soda
1/4 cup white vinegar
The surface of bathroom sinks become marred by a thick film of soap scum and white scale from hard water. These tough stains cling to your sinks despite wiping with commercial bathroom cleaners. Soap scum and water stains require products that break down and dissolve the substances without harming the sink surface. Using abrasive tools on the sink may leave tiny scratches within the surface. Use the right tools and products to remove dingy stains from bathroom sinks.
Mix 1/2 cup baking soda with 1/4 cup white vinegar in a bowl. Add a little more vinegar if needed to create a thick paste.

Wet the bathroom sink with warm water. Sprinkle salt generously over the bathroom sink.
Apply the baking soda and vinegar paste to the stains on the sink with a sponge. Allow the paste to remain on the stains for five to 10 minutes.
Scrub the stains and the entire sink and faucet with a nylon scrubber. Use an old toothbrush to scrub around the base of the faucet and the drain hole. Add more paste to the stains if they remain on the sink surface. The agitation from the paste, salt and nylon scrubber help to remove the stains.
Wet the nylon scrubber periodically to help with scrubbing. Rinse the sink with cool water and a sponge after removing all the stains.
Dry the sink and faucet with a towel to prevent the appearance of water spots.
