How to Clean a Porcelain Kitchen Sink?

Cleaning porcelain kitchen sinks are different from cleaning other types of sinks because they are non-porous with a hard surface.

They are also highly susceptible to staining and wear and tear due to daily use.

Maintaining the cleanliness of these sinks is important to give your bathroom or kitchen a clean look.

If you don’t clean them properly, they begin to lose their luster and wear out quickly.

In this article, we are going to focus on the different methods of cleaning a porcelain kitchen sink.

These methods will help eliminate all kinds of stains and prevent any further wear and tear.

Without further ado, let’s dive right in and walk you through the process. Here’s all the material and tools that you’ll need to get started!

What Can Make Porcelain Sink Dirty?

Since most sinks are exposed to lots of soap and cleaning liquid, they dull over time.

The water used in the sinks also has high mineral content, so it contributes to the rusting of the sink surface.

Moreover, products like facewashes, shampoos, hair dyes, and nail polish, etc., also contain chemicals that wear out the porcelain.   

If your porcelain sink is in your kitchen, then its biggest culprits are likely to be food scraps, coffee, and tea bags, etc.

If you put all your silverware in the sink directly, that also scuffs up the surface of the porcelain pretty badly.

To maintain a clean and shining porcelain sink, you need to take protective measures and also take care of the cleaning and maintenance of the sink.

Cleaning the Porcelain Kitchen Sink – Step-by-Step Guide

Here’s a step-by-step guide that you can follow to clean your porcelain kitchen sink:

Step #1: Clean the Sink with Cleaning Liquid Gently

The first step is to use the sponge and clean the sink gently. Use liquid soap and warm water to soak the sponge and clean the sink with it.

Make sure you clean all kinds of buildup from the surface, such as toothpaste, food scraps, soap leftovers, etc.

During this step, all the easy-to-remove stains are eliminated, and all the stubborn ones are identified.

Wash the liquid soap down the drain and clean the sink with a dry dishtowel.  

Step #2: Remove Discoloration of the Porcelain Sink

The second step doesn’t involve any scrubbing, as we’ll focus on removing the discoloration of the porcelain sink.

Excessive scrubbing right away can cause the sink to wear and tear. That is why we need to begin the cleaning process gently.

If your porcelain is white, then you need to use bleach to get rid of discoloration. In the case of a colored porcelain sink, you’ll have to use hydrogen peroxide.

If you have a white porcelain sink, you can use bleach to remove stains that cause discoloration.

Make sure you don’t use chlorine bleach on vintage or colored porcelain because it will severely damage its finishing.

A good alternate option of chlorine bleach is liquid oxygen bleach. Consider using hydrogen peroxide for your colored and vintage porcelain.

Although it requires more work, it’s much safer than chlorine bleach.

  • First, take a spray bottle and fill it with your choice of bleach-based on the type of porcelain.
  • Then, use paper towels to cover the sink.
  • Apply the bleach on the towels by spraying them. Let it soak and sit for at least half an hour.
  • Finally, remove the soaked paper towels and use running water to rinse and clean the sink thoroughly.

If you’d rather not use bleach at all, then white vinegar is another great alternative. Take a spray bottle and add undiluted white vinegar to it.

Spray your porcelain sink with white vinegar and clean it with a nonabrasive sponge gently.

Then, rinse the sink using running water, and your sink will be clean as new.

If there are a few stubborn stains leftover, then you may have to use oxygen bleach after all.

Just make sure that you wash away the vinegar properly so it doesn’t have any damaging reaction when getting in contact with bleach.   

Step #3: Use a Mild Abrasive to Clean Deeper Stains

Although bleach should clean away all kinds of stains, you’ll have to use a mild abrasive if you don’t use bleach in the second step.

Get a gentle abrasive and try to lift and remove the stain from your porcelain sink.

However, make sure that you get an abrasive that is compatible with porcelain because others can damage it.

We recommend getting Bar Keepers Friend for your porcelain sink. They are easily available at Walmart or any other general store.

It’s an effective yet safe abrasive that can help remove more stubborn stains.

All you need to do is apply a small amount on the surface of your porcelain sink and then rub the surface gently with the help of a nonabrasive sponge.    

Bar Keepers Friend has acidic properties, and it lifts tougher stains.

However, make sure you don’t overuse it or use it too frequently, as that can lead to the discoloration of the porcelain.     

Some Other Methods of Cleaning Porcelain Kitchen Sink

Here are a few other options for you to clean your porcelain sink effectively and safely.

Cleaning Silverware Stains with Naval Jelly or Acid

If your porcelain sink has lots of silverware or metal stains, then this method is a great option for you.

Add a few drops of lemon juice onto your sink and let it sit for a few minutes. Make sure you don’t scrub the surface and just wash it off with water.

If your porcelain sink has rust stains, then naval jelly is a highly effective option for removing them.

It is easily available at general or grocery stores, and you can also order it online.

Apply the naval jelly in the form of a thin coat over the stained area of your sink. As soon as you notice the change in color of the stain, wash it down with water.

Don’t let the naval jelly stay on for too long, as it can damage the porcelain over an extended period of exposure.   

Cleaning Minor Stains with Baking Soda

Baking soda is another great option if your porcelain sink has minor or light stains.  

It is a mild abrasive that doesn’t damage your porcelain and cleans the stains safely.

If you regularly use baking soda to deep clean your porcelain sink, you’ll never have to use any harsh abrasive again.

Baking soda keeps surfaces clean from mild stains and layers of residue without damaging the porcelain enamel.

Here’s how you can use baking soda for cleaning your porcelain sink regularly. All you need is half a cup of baking soda and a nonabrasive sponge or damp cloth.

First, rinse your porcelain sink with water and use a sponge or damp cloth to wipe it gently.

Apply baking soda by sprinkling it on the sink’s surface; make sure you cover the stained areas. Now, gently scrub it with the cloth in a circular motion.  

You can also make a baking soda paste by mixing it with half part water and using it as your sink cleaning soap.

To increase its effectiveness, you can also add a bit of ammonia, lemon, or white vinegar to the mix.

This will get rid of the more stubborn stains. However, you need to ensure that you wash it off after cleaning, so its residue doesn’t make the surface dull.  

How to Refinish a Kitchen Porcelain Sink after Cleaning?

After you are done cleaning the porcelain sink and removing all the stains, you should consider refinishing the sink for a better and long-lasting effect on the results.

A durable and effective finishing will protect the sink from residue buildup and keep it shining and clean for longer.

Final Thoughts

Cleaning a porcelain sink is different than cleaning other types of sinks, but it’s not impossible or even difficult.

The only thing that you need to be careful of is not to use highly abrasive cleaning tools or strong cleaning products.

You can clean your porcelain kitchen sink safely by using the methods that we have explained in detail above.
