There’s just something nice about a shiny stainless-steel sink, and thankfully, it’s really easy to make it clean and shiny. No special cleaners needed. No chemicals. No weird combinations of various cleaning supplies. Just one thing: baking soda
Remove stuck on food and grease and then sprinkle a light amount of baking soda all over your sink, paying special attention to the corners and drain.
Get out an old toothbrush (a sponge would work too, but I find that a soft toothbrush works best in the corners and drain, so I just use it for the whole sink), run it under water (in your sink with baking soda) for a few seconds and start scrubbing (lightly!) in circles.
Start with the sides of your sink, moving down, and finishing with the drain. Scrub the drain well, since that’s where most of your stains will likely be. If you need more water, run a bit in the sink and then shut it off. Don’t leave the water running, or all your baking soda will disappear.
Finish off your cleaning by rubbing a mixture of baking soda and water on the top of your sink, and on the faucet (use a rag or sponge for this). Wipe clean with a damp rag. Rinse out your sink so there is no baking soda residue. If you still see stains, add some more baking soda and scrub again.
That’s it! A clean, shiny stainless-steel sink in only 15-20 minutes, using only 1 very inexpensive product.
