If you are looking for an effective, natural way to clean doorknobs, why not try baking soda?

Baking soda is inexpensive, easy to use, and is known for its abrasive qualities.

It’s also a good choice if you don’t want to expose yourself to chemicals while cleaning.

In this article, we’ll discuss what a doorknob is, how often it should be cleaned and why using baking soda makes sense!

Let’s begin.

What You’ll Need:

To clean your doorknobs, you’ll need:

  • A rag or cloth (preferably microfiber)
  • A paper towel or two
  • Baking soda (I use about 1/4 cup per knob)
  • Water


  1. Mix baking soda with water to make a paste. The more baking soda you use, the more abrasive the paste. Use your best judgment.
  2. Use a rag to clean the doorknob with the baking soda paste. 
  3. Rinse off the scrubbed doorknob. Make sure all traces of baking soda are gone. 
  4. Dry it with another cloth or paper towel.

What is a Doorknob?

A doorknob is a piece of hardware that is used to open and close a door. The knob or handle part of the doorknob can be rotated by hand, allowing you to open or close the door. Most doorknobs are made of metal or plastic, although some are also made from wood.

How Often Should You Clean Doorknobs?

You should clean your doorknobs once a week, as it is a good practice to take care of your home and keep it clean. If you have kids or pets, you may want to clean them more often. 

Why Use Baking Soda for Cleaning Doorknobs?

Baking soda is made up of sodium bicarbonate, an odorless and tasteless powder that’s been used for centuries. It can be used to clean your home naturally, as well as whiten laundry and remove stains from clothing. Here are some reasons why you should use baking soda for cleaning doorknobs:

  • Baking soda is a mild abrasive – since it’s more abrasive than water alone, it helps scour off the dirt that other household cleaners would miss. This makes it ideal for cleaning items like doorknobs which may have gotten grimy over time due to daily use by different people in the house (and their dirty hands).
  • Baking soda is a mild deodorizer – when mixed with warm water to form a paste, baking soda can help neutralize odors and deodorize your doorknob naturally.
  • Baking Soda has disinfectant properties – this means that if you clean your doorknob with baking soda, it will kill icky germs as well.

Benefits of Having Clean Doorknobs

Having clean doorknobs is important for you and your family’s health and safety. It allows you to touch the doorknobs without worrying about spreading germs, which can cause illnesses. 

Cleaning your doorknobs regularly will also make them look nicer, so they’re more attractive to guests.

Clean doorknobs are easier to use since they are less prone to become stuck due to dirt buildup.

Doorknob Materials to Avoid Cleaning with Baking Soda

You should avoid using baking soda on materials that are soft or easily scratched. Abrasive cleaning products like baking soda can scratch glass, wood doors, and stone.

  • Glass: Because baking soda is an abrasive substance, I don’t recommend cleaning glass with it. It’s better to use a product specifically designed for glass surfaces like Windex or OxyClean Max Out Spray Cleaner (which you can find at The Home Depot).
  • Wood: If your doorknob is made of wood, then I recommend using something other than baking soda if possible—or at least test out a small spot before fully committing.


Now that you know how to clean doorknobs with baking soda, you can finally get rid of all those annoying germs! I hope you’ll give this natural method of cleaning your doorknobs a try.
