What Is Porcelain Or Ceramic?

Both porcelain and ceramic are made from a clay composite that is fired at very high temperatures in a kiln. Sinks can be cast iron underneath and coated with porcelain or ceramic.

The difference between the two is that porcelain is essentially denser, making it more robust, largely because porcelain is not only fired at higher temperatures, but the clay used is purified with fewer additives.

7 Ways – How To Clean A Ceramic Or Porcelain Sink

It is difficult to keep a ceramic or porcelain sink spotless. Whether you have the porcelain sink in the bathroom, with soap scum, dirt, and bacteria tarnishing your beautiful sink or you have a porcelain sink in the kitchen with food stains, red wine, tea, and coffee leaving visible stains.

We have 7 different ways to eliminate any stain in no time with minimum hassle.

Cleaning a Ceramic or Porcelain Sink With Baking Soda

Baking soda is excellent at cleaning and is non-toxic. You can mix baking soda with other cleaning agents but most stains will come out using just baking soda.

  • Wet your sink and sprinkle 2-3 teaspoons of baking soda into it.
  • Use a scourer (not a metal one) or sponge and gently rub the stained areas in a circular motion.
  • Leave to sit for 10 minutes.
  • Rinse and repeat for those tougher stains.

Cleaning a Ceramic or Porcelain Sink With Baking Soda And Lemon

As mentioned earlier, baking soda can be mixed with other items in your kitchen to make a potent cleaning agent. Lemon and baking soda creates a reaction due to the acidity and breaks down the stains.

  • Wet your sink and sprinkle 2-3 teaspoons of baking soda into it.
  • Cut the lemon into 6-8 wedges depending on the size of the lemon.
  • Start to scrub the sink using the lemon wedges, concentrating on the stained areas.
  • Once the juice in the wedge finishes, get a fresh lemon wedge. You can add more baking soda if needed.
  • Rinse and marvel at your shiny sink that now smells of fresh lemons.

Cleaning a Ceramic or Porcelain Sink With Baking Soda And Hydrogen Peroxide

If you have a black, gray, or any colored sink then hydrogen peroxide is very useful as it will not react with the color as some bleach-based cleaners will. It will not only clean the sink it will kill any germs lurking around in the sink.

  • Pour the hydrogen peroxide into a spray bottle and have it ready.
  • Sprinkle 2-3 spoons of baking soda into the sink covering the stains as much as possible.
  • Spray the hydrogen peroxide over the sink a little at a time.
  • Scrub the sink using a green scourer to remove any stains.
  • Rinse with water until all the baking soda has been washed away.

If you are at all worried about using hydrogen peroxide on your sink, then vinegar is the next best solution.

Ammonia can have a pungent smell, but it is very effective at cleaning and killing any germs.

Vinegar is another versatile household cleaner that can be used in conjunction with other agents to clean your home. It not only cleans the sink but it removes mineral build-up and disinfects the sink at the same time.

  • Wet the sink and use the paste you made and scrub your sink with a non-metal scourer to remove any stains.
  • Rinse well with water leaving no residue of the paste.
  • Enjoy your gleaming sink and repeat the process for the pesky stubborn stains if needed.
