It is easy to make tiles sparkling. After all, there are a lot of cleaning agents that do the work. However, no matter how clean the tiles are, they will look tired and old if the grout is dirty. So, how can you make the grout look clean and new naturally? Does baking soda clean grout?

Yes, baking soda cleans grout. While you can use many cleaning tools to clean grout, baking soda is the easiest and most effective cleaning tool in your pantry. You can use baking soda alone without using other substances. But if the grout is too dirty, you might need to add a compound to mix it with baking soda.

So, don’t panic if the grout on your floor or walls at home is a mess. Cleaning them is easier than you think. Here are effective ways to clean grout with baking soda.

How Does Baking Soda Clean Grout?

Does baking soda alone clean grout? Well, the answer is yes. Baking soda, also called sodium bicarbonate, has many uses for cleaning.

Best Tips Before Cleaning Grout with Baking Soda

Before we dive into the exciting part, here are some tips and tricks you should know. This will help you better clean stubborn stains and dirt on the grout lines.

  • Use Electric Toothbrush

An electric toothbrush is an optional tool for cleaning the grout. This tool will prevent using too much elbow grease with an old toothbrush or scrub brush. It will serve as your mini tile grout cleaning machine.

  • Avoid Straight Vinegar

If you want to mix baking soda with vinegar, use white vinegar instead of straight vinegar. Straight vinegar is a popular cleaning ingredient but is too acidic for cleaning grout.

  • Pour Boiling Water Into the Grout

Before cleaning the grout, you can pour boiling water into the affected area. The heat will help remove the grime. 

  • Leave the Baking Soda Mixture on the Grout

If the grout is very grimy or dirty, set the paste onto the grout for around 10 minutes. 

If you use baking soda and hydrogen peroxide paste (we cover this below), leave the mixture for 15 to 20 minutes. Let it sit because it takes time for the whitening properties to work.
