While porcelain sinks may be one of the best kitchen sinks out there and are known for their durability, they’re also prone to damage and scratches. If you’ve wondered how to get scratches out of a porcelain sink, we’re here to help.  

In this guide, we’ll provide you with everything you need to know, from how to clean porcelain sink scratches to preventing them and more.  

If you’re wondering how to remove scratches from porcelain, here are some ways to get started.  

1. Pumice stone method  

For this method, all you would need is a pumice stone. It is important to note, however, that this method is only suitable for minor scratches.  

  • 1
    Start by plugging your porcelain sink with a drain plug before filling it with about ¼ inch of water.  
  • 2
    Then, dip your pumice stone into the water, ensuring that it is completely wet.  
  • 3
    Once your pumice stone is wet, go ahead and buff the scratch marks that appear on your sink. Make sure that you’re doing it in the direction of the scratch in a back and forth motion until it disappears.  

This method isn’t overly difficult for a homeowner to do; however, you need to make sure that your pumice stone is completely wet; otherwise, you run the risk of scratching your sink.  

2. Baking soda method

With the baking soda method, you would need the following:  

  • Baking soda  
  • A soft damp cloth  
  • 1
    Start by sprinkling baking soda over the length of the scratch, ensuring that it's properly covered. 
  • 2
    Then, go ahead and buff the scratches with a soft damp cloth in a back and forth motion.  
  • 3
    Finally, rinse the baking soda from your porcelain sink with tap water.  

This is also a relatively straightforward method but is more suitable for minor scratches.  

3. No scrub method  

If you’re not a fan of scrubbing, this is a good method to get rid of any minor scratches. You would need:  

  • Baking soda  
  • Hydrogen peroxide 
  • Paper towels 
  • A spray bottle  
  • 1
    Start by plugging the sink before spraying it lightly with water.  
  • 2
    Then, sprinkle the surface of the sink with a good amount of baking soda.  
  • 3
    Once that’s done, go ahead and cover the surface with paper towels before spraying it with hydrogen peroxide.  
  • 4
    Finally, allow it to set for a couple of hours before rinsing your sink with water.  

If you have deep scratches on your porcelain sink, you should consider purchasing a porcelain repair kit. 

This nifty kit will allow you to fill in scratches and ensure that it’s properly covered and unnoticeable. If you do choose to use a porcelain repair kit, however, just know that it does require a little more work.  

What Causes Scratches On Porcelain Sinks? 

If you’ve noticed some scratches on your porcelain sink, it’s likely that it came from any one of the following:  

  • 1
    Pots, pans and other kitchen utensils 
    After you’ve used your pots and pans for cooking, it’s easy to accidentally scratch your porcelain sink when you’re scrubbing them clean. This can also happen by tossing utensils into the sink.  
  • 2
    When drying your hair, it's possible that you could have accidentally knocked your hairdryer into your porcelain sink, resulting in a scratch.  
  • 3
    Curling irons  
    Similar to hairdryers, your curling iron could have accidentally come into contact with the porcelain sink and caused a scratch.

4 Friendly Products For Removing Scratches

If you're looking at how to get scratches out of a porcelain kitchen sink, here are some suggestions to get you started.  

1. Bleach

While it might be tempting to use abrasive cleaners to remove scratches from your porcelain sink, you should avoid doing so. Instead, try filling your sink with warm water and adding about two cups of bleach before letting it soak overnight. If the scratches on your sink are minor, they should be completely removed by morning.  

2. Bar Keeper’s Friend  

This nifty commercial cleaner is typically available in either a scouring powder or a scrubbing cream. If bleach doesn’t work, you should definitely give Bar Keeper’s Friend a go.

All you’ll need is a pair of gloves and a sponge (just make sure that it isn’t overly harsh). Once you’ve removed the scratches, you can also use this cleaner for your cookware, kitchen, bathroom, and more.  

3. Baking Soda

If the scratches on your porcelain sink are minor, baking soda is a good solution. Simply sprinkle baking soda over the scratch before buffing it with a cloth that’s soft and damp. Make sure that you’re rubbing the baking soda on the entire length of the scratch in a back and forth motion.

After a couple of minutes of rubbing, rinse it off with warm tap water, and you’re good to go.  

4. Pumice Stone  

Another good method to try is utilizing a pumice stone. To do so, you’ll go ahead and plug your sink with a drain plug before filling it with ¼ inch of water. Then, dip your pumice stone into the water (ensuring that it’s completely wet) before using the pumice stone to smooth and buff away the scratches.

It’s important to note that the pumice stone is suitable for minor nicks and scratches but isn’t the ideal solution for deep scratches.  

How To Protect Porcelain Sink From Scratches 

There is plenty that you can do to protect your porcelain sink from scratches. By protecting your porcelain sink, you will be able to keep your porcelain sink in good condition for many years to come. Here are some tips to get you started:  

  • When cleaning the interior of your porcelain sink, you’d want to use a soft cleaning sponge.  
  • Make sure that when you’re cleaning your porcelain sink, you’re using mild detergent solutions that are non-abrasive.  
  • After you’ve used your sink, make sure you rinse it with clear water, as leaving dirt particles on your porcelain sink can cause scratches.  
  • Avoid pouring any acidic liquids onto the surface of your porcelain sink.  
  • If possible, try and place a rubber dish mat at the bottom of your porcelain sink, as this can help to protect your porcelain sink from any scratches.

How do I keep my porcelain sink white?  

If you have a white porcelain sink, you can use bleach to keep it white. If you have a colored porcelain sink, however, you would want to make sure you’re using liquid oxygen bleach (hydrogen peroxide).  

Do ceramic sinks mark more easily?  

No, ceramic sinks don’t mark more easily. Ceramic is a highly-resistant material and liquids can run off this material very easily, so when well taken care of, it’s not easy for marks to form.  

How long do porcelain sinks last? 

It depends on how well you take care of your porcelain sink. If you take care of your porcelain sink properly, on average, porcelain sinks can last between 25 and 30 years.  

How much does a new porcelain sink cost?  

It depends. If you purchase enameled porcelain sinks, it could be around 200 to 300 dollars for a single bowl. However, if you choose a different color, prices tend to increase, and some specialty colors could cost 500 dollars or more.  


If you've noticed that there are minor scratches on your porcelain sink, don't fret, as they're usually relatively easy to remove. 

Deeper scratches, however, can be much more challenging to get rid of; hence, it's important that you take proper care of your porcelain sink to ensure that it stays in pristine condition for a good period of time.
