Understanding Your Porcelain Sink

Before we dive into the cleaning process, it’s important to understand what porcelain sinks are made of. Porcelain is a type of ceramic that is baked at high temperatures to create a hard, durable surface. It’s often coated with a glaze to give it a glossy finish. This glaze can be white, colored, or even vintage porcelain, depending on the type of porcelain used.

Porcelain sinks can be made from cast iron or metal, and they are known for their durability and resistance to stains and scratches. However, they can still get dirty and stained over time, especially if they are not cleaned regularly.

How to Clean Your Porcelain Sink

Cleaning your porcelain sink doesn’t have to be a tough task. Here’s a step-by-step guide on how to get your sink clean and remove surface stains.

Step 1: Basic Cleaning

Start by rinsing the sink thoroughly with warm water. This will help to loosen any surface dirt and grime. Next, use a non-abrasive sponge and dish soap to scrub the sink in circular motions. Pay special attention to the bottom and sides of the sink, where dirt and stains tend to accumulate.

After scrubbing, rinse the sink again to remove the soap and water. Dry the sink with paper towels to prevent water stains.

Step 2: Dealing with Tough Stains

For stubborn stains, you’ll need to use a stronger cleaner. Baking soda is a great option as it’s a natural abrasive that can help to scrub away tough stains without damaging the finish of your porcelain sink.

To use baking soda, sprinkle it over the stained area of your sink and gently scrub with a sponge. For really tough stains, make a paste of baking soda and water and apply it to the stain. Let it sit for a few minutes before scrubbing and rinsing the sink thoroughly.

Another effective cleaner for tough stains is Bar Keeper’s Friend. This cleanser is specifically designed to remove stains from porcelain and other hard surfaces. Just be sure to follow the instructions on the packaging.

Step 3: Disinfecting Your Sink

After you’ve removed the stains, it’s a good idea to disinfect your sink. You can use bleach for this, but be careful not to use too much as it can discolor your sink, especially if it’s colored porcelain. Use bleach on white porcelain only.

To disinfect your sink with bleach, fill the sink with warm water and add a small amount of bleach. Let it sit for a few minutes before draining and rinsing the sink thoroughly. If you prefer a natural disinfectant, you can use white vinegar or lemon juice instead of bleach.

Step 4: Polishing Your Sink

The final step in cleaning your porcelain sink is to polish it. This will help to restore its shine and make it look like new. You can use a commercial porcelain polish for this, or you can make your own by mixing a few drops of lemon juice with baking soda.

Apply the polish to your sink with a soft cloth, rubbing it into the porcelain in circular motions. Let it sit for a few minutes, then rinse and dry your sink.

Maintaining Your Porcelain Sink

Now that your porcelain sink is clean and shiny, you’ll want to keep it that way. Here are some tips to maintain your sink and prevent future stains:

  1. Regular Cleaning: Clean your sink regularly with soap and water to prevent buildup of dirt and grime. Rinse and dry your sink thoroughly after each use to prevent water stains.
  2. Avoid Harsh Chemicals: Avoid using harsh chemicals or abrasive cleaners on your porcelain sink, as they can scratch and dull the finish. Instead, opt for gentle, non-abrasive cleaners.
  3. Tackle Stains Immediately: As soon as a stain appears, tackle it immediately. The longer a stain sits, the harder it will be to remove. Use baking soda or Bar Keeper’s Friend to remove stains from a porcelain sink.
  4. Protect Your Sink: Use a sink mat or a dish rack to protect your sink from scratches and scuff marks. Avoid dropping heavy pots or pans into the sink as they can damage the porcelain.
  5. Avoid Metal Objects: Metal objects like steel wool or metal scrub brushes can scratch the porcelain. Instead, use a soft sponge to scrub your sink.

By following these tips, you can keep your porcelain sink looking its best for years to come.


Cleaning a stained porcelain sink may seem like a daunting task, but with the right tools and techniques, you can get it clean and sparkling in no time. Remember, the key is to clean regularly, tackle stains immediately, and use gentle, non-abrasive cleaners. With a little effort, you can keep your porcelain sink looking as good as new.

Remember, a clean sink is not only more pleasant to use, but it also makes your whole kitchen or bathroom look and feel cleaner. So roll up your sleeves, grab your sponge, and get to cleaning!
