How to Clean A Porcelain Sink

Cleaning Tips

4 Aug

Porcelain sinks are notorious for scratching and staining. Many think you need to grab harsh chemicals, like bleach, to really get it clean and white again, but there is an easy method that completely whitens, brightens, and cleans a porcelain sink with no harsh chemicals and minimal work. Ready to learn how to clean a porcelain sink… naturally?

How to Clean A Porcelain Sink Naturally
 

I have a porcelain sink in my kitchen and it seems to stain and scratch so easily. For the longest time, I cleaned it with diluted bleach, but I didn’t like using such a harsh chemical; and it didn’t remove any of the scratches. I started looking for an alternate cleaning solution. I have two sides to my porcelain sink, so I tried out two different methods. My intention was to share both cleaning solutions, but one was far superior in cleaning the porcelain sink, so I decided to just share one! (I’ll share what didn’t work as well, so you don’t waste time with that method.)

What You Need to Clean A Porcelain Sink

Items needed to clean a porcelain sink: baking soda and hydrogen peroxide

Ingredients Needed to Naturally Clean A Porcelain Sink

  • Baking Soda
  • Hydrogen Peroxide

Supplies Needed to Clean A Porcelain Sink

  • Sponge

How to Clean A Porcelain Sink

Begin by wetting down the bottom and sides of the sink with water, then sprinkle on some baking soda. You just need a fine layer; no need to heap it on.

Using a sponge, scrub the baking soda around the sink. Baking soda is a very mild abrasive that absorbs stains. I immediately noticed the brownish color start to disappear with hardly any effort.

Scrubbing porcelain sink with baking soda
 

Once the sink has been thoroughly scrubbed with the baking soda, add a small amount of hydrogen peroxide to the sponge and scrub a little more.

The scratches should start to disappear and the sink will whiten up. You may have a few baking soda clumps in the sink. No worries; this is normal. After thoroughly scrubbing with the hydrogen peroxide, rinse everything down the drain.

As I mentioned, I tried an alternate method using equal parts Cream of Tartar and Vinegar. I scrubbed and scrubbed, and while it worked a little, it was nothing like the method described above. Here’s the process on the other side of the sink.

How Much Can You Save?

Buy Sink Cleaner

  • Bar Keepers Friend= $11.31 for 24 oz. (Price on Amazon 3/27/24 at 8:33pm. Prices subject to change)- The reason I chose this particular sink cleaner is because it had a lot of great reviews and it looks like it does an amazing job. If you are interested, go for it. However, if you are looking for a cheaper, more natural version, see below.

Make Your Own Porcelain Sink Cleaner

  • Approximately 1/4 Cup Baking Soda=  12¢ (based on Target’s price of 99¢ for 16 oz.)
  • Approximately 2 Tbsp. of Hydrogen Peroxide= 3¢ (based on Target’s price of 99¢ for 32 oz.)

The total amount made was 3 ounces, based on 2 oz. of Baking Soda and 1 oz. Hydrogen Peroxide.

Savings

This means that for 24 ounces of sink cleaner from Amazon (costing $11.31), you could make 24 ounces of your own sink cleaner for $1.20, saving $10.11.

    I forgot about wiping down the after I put baking soda on the porcelain. So I took paper towels and laid them on top of baking soda and poured hydrogen peroxide and let it soak all night. I have a brand new sink. Thank you for the idea

    I have an old farmer’s sink that is so stained and scratched. I’d like to try this. Question is: Why are you plugging the sinknif you’re not putting any liquid in it? My sink can’t be plugged so wondering if I should even try.
    Thanks

    • Erin says

      March 7, 2018 at 9:23 AM

      The only reason I plugged the sink was to keep the baking soda from going down the drain before I finished scrubbing it around. There is certainly no need to plug the drain 🙂

      “Once the bottom and sides of the sink are wet, plug the drain and sprinkle on some baking soda. You want a fine layer of baking soda; no need to heap it on. Scrub the sink using a sponge. This is like a magic stain eraser. The brownish color in the sink literally started disappearing before my eyes and was soaked up in the baking soda.

    I can’t believe how beautiful it looks now after using your technique. I don’t care if it dulls it more or not, it looks 100% better. Thank you, thank you and thank you

    My other tabs I have open on my browser are “Bar Keepers Friend” on Amazon and “How much does a new sink cost” on Google results. My sink was so disgusting I truly thought it was done for. I went from brown, scratched, truly ugly porcelain sink to a brand new looking sink in about 10 minutes (I got so excited I didn’t read down to where it said leave it sitting for 10-15). I just got the sink wet, sprinkled a good quarter of a box of baking soda all over it, dumped some peroxide haphazardly on a sponge, and started scrubbing. I used a toothbrush to get the stainless drains. It is literally just the sink just came out of the box. THANK YOU.

      Hi Susie- Thanks for your question. Using baking soda does create a mild abrasive, which could, potentially, dull your sink. I have had great success with it, however, if you’d like to try a different method, I have heard wonderful things about Bar Keeper’s Friend, although, I, myself, have never tried it. Hope that helps.

    After I started cleaning my sink with baking soda, it seems to get stains much more easily. It seems the baking soda leaves it more naked or vulnerable. Like I have to keep doing it more frequently. I wash the coffee grinder there daily also. What can I use to seal it or protect it after stripping it with baking soda?

    It worked great, especially considering my sink is 50 plus years old. I also used the cleaner on the white (at least they were white when I bought them) sink mats. Did a pretty good job. No fumes makes it a keeper for me. I need a cute bottle for the peroxide under my sink and a shaker for my baking soda. By the way, my old sink’s are a light yellow.
