Step One: Rinse with hot water.
Step Two: Sprinkle all over with baking soda. I use a damp cloth to cover the rim, sides of the sink and the tap.
Step Three: Spray with white vinegar. Watch the two fizz together.
Step Four: Scrub with a soft-bristled brush. Make sure to also clean the sink strainers.
Step Five: Rinse off with warm water. Use a cloth on the rim of the sink and the tap. Buff with a dry, clean cloth.
Enjoy your shiny sink!
