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.

Porcelain Sink 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.  

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.  

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.  

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.  

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.

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

People Also Ask (FAQs)

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.  


Conclusion

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.
