Porcelain sinks are notoriously susceptible to stains and scratches and require a consistent cleaning regimen. If you've ever defaulted to harsh chemicals like bleach to spruce up your porcelain sink, we have an alternative, environmentally-friendly solution for you to consider. With a little attention and some natural household products like baking soda and lemon juice, your porcelain sink will be back to its shiny self in no time.

How Often to Clean a Porcelain Sink

The longer you leave food residue and toothpaste gunk lingering in your porcelain sink, the harder it will be to remove. Tackle grime before has a chance to set and stain. The best way to keep your porcelain sink looking squeaky clean is with a light cleaning every so often. We recommend you use a gentle scrubber or a sponge, some dish soap, and a little warm water at least once a week.


Avoid using hard abrasive materials like steel wool to clean your porcelain sink. The rough material can dull the finish on your sink and may even scratch it.

How to Clean a Porcelain Sink

  1. Start With a Quick Clean

    Before you pull out the big guns, give your porcelain sink a quick clean with some gentle dish soap and a sponge. Wipe away any grease or soap scum, then rinse everything down the drain.

  2. Sprinkle With a Layer of Baking Soda

    Sprinkle some baking soda over the stains or directly onto a damp sponge or microfiber cloth when you're ready to deep clean your sink. Scrub lightly and in a circular motion.

    The baking soda alone may lift the stains from your porcelain sink, but if you need a tougher solution, move on to the next step before rinsing your sink clean.

  3. Add Hydrogen Peroxide to the Mix

    If the baking soda hasn't relieved your sink of all its stains, hydrogen peroxide may do the trick. Cover your sink in a layer of paper towels, then use a spray bottle to spray the hydrogen peroxide all over. You want the paper towels to cling to the sink's surface, then leave them to sit for at least 30 minutes (up to an hour).


    If you don't have hydrogen peroxide handy, an alternative solution is white vinegar. This household cleaner is often paired with baking soda, and the combo can be used to clean many other areas of your home.

  4. Rinse Your Sink Clean

    After the baking soda has done its job and the hydrogen peroxide has had a chance to sit, remove the paper towels and rinse out your sink thoroughly. Wipe the inside of your sink with a microfiber towel to finish the job. If you see any leftover stains, move on to the final two steps.

  5. Tackle Tough Stains

    If you see an orange or red discoloration in your porcelain sink, it's likely a rust stain and should be cleaned with a separate method. Add a few drops of lemon juice or spray the stain with white vinegar. Avoid mixing either of these acids with each other or hydrogen peroxide, as the combination can be toxic. Whichever you choose, allow the liquid to sit for a half hour. You should notice the stain change color, after which you can rinse away the residue with warm water.

  6. Finish With a Thorough Rinse and Buff

    When you've finally removed all the gunk and grime, give your porcelain sink one last rinse with warm water. Feel free to use a little dish soap as well, to be sure you've washed away any remaining cleaning solution. To finish, wipe down the sink, faucet, and surrounding area with a microfiber cloth.
