To make the DIY solution, take one cup of warm water in a bowl and add two tablespoons of dish liquid. Mix them well until the dish liquid dissolves. 

Step two: Clean The Kitchen Sink

We recommend avoiding any harsh chemical-based cleaners because they can damage the sink. Take the solution we made in step one, dip a sponge into it, and squeeze an extra solution.

Wipe away the entire kitchen sink with this cleaning solution dampened sponge and leave it for a few minutes.

Now rinse away the kitchen sink with cold water, do it twice to make sure the entire kitchen sink is cleaned properly.

Step Three: Disinfect the Kitchen Sink

If you own a steel kitchen sink, you have to disinfect it with vinegar or hydrogen peroxide, and if it’s a porcelain sink, you can disinfect it with bleach.

As most of us own a steel sink, let’s know how to disinfect a steel sink. Before starting the disinfection process, make sure you have to wear protective gear; getting in touch with your skin can cause irritation and other skiing problems. Sometimes people with asthma face breathing problems.

You can disinfect steel sinks in two ways, using vinegar and hydrogen peroxide.

  • Option One: Vinegar

Plug the drain, fill half of it with warm water and rest with white vinegar. Use a large spoon or something like it to mix the warm water and white vinegar.

You can also make this solution first and then pour it into the sink. Damp a sponge in this solution and wipe away the kitchen sink handles and faucet area. Leave it for 8-10 minutes in the sink.

Once time is up, drain the sink and wipe away with clean water a damp sponge to completely clean the residue. Allow it to air dry.

  • Option two: Hydrogen Peroxide

Disinfecting with hydrogen peroxide is the same as the vinegar process. You just have to make the solution with different ingredients and different amounts.

Take a gallon of water, add one-fourth cup of hydrogen peroxide and mix it well. Next, follow the same disinfecting process we described above with vinegar.

Step Four: Polish the Kitchen Sink

Once disinfecting is done, it’s time to polish the kitchen sink to get back its shine. After using acidic ingredients, the steel sink won’t be the same shiny sink.

So you have to polish it. You can polish it with olive oil or lemon juice. Take some olive oil or lemon juice in a microfiber cloth and wipe away the sink.

Step five: Wipe Away With A Dry Microfiber Cloth.

This step isn’t to be followed after cleaning or disinfecting the sink; try to follow it every time you use the kitchen sink.

After using or cleaning it, make sure to wipe away the kitchen sink with a dry microfiber cloth. It will keep the sink in good condition and will increase its lifespan.

How to Disinfect Kitchen Sink with Bleach

Disinfecting a kitchen sink with the beach is simple when you know the right way to use it. If you use bleach without knowing how to use it, you will damage your kitchen sink.

Bleach is a highly effective disinfectant; that’s why it’s alone enough for disinfecting. And you can’t mix it with any other ingredients ( won’t need)  leaving the water.

Mixing with other cleaning agents like vinegar, rubbing alcohol, or ammonia can cause a chemical reaction. So be careful.

  • Take warm water and bleach in a 1:50 ratio. You can mix it outside the sink or directly fill the basin with warm water and add a capful of bleach.
  • Use a large stick and mix the ingredients. 
  • Dip a sponge in this solution and wipe away the kitchen faucet, including the handles and other outside parts. Leave it for 5-8 minutes.
  • Once time is up, open the plug and drain the solution. Now rinse away with clean water. To clean additional parts, use a damp sponge and wipe away.
  • Use a dry microfiber cloth or kitchen towel and wipe away the entire kitchen sink to absorb excess moisture and allow it to dry naturally.
