If you’ve ever found yourself cringing at the unpleasant odor from your shoes, you may wonder if there’s a simple solution to freshen them up.

The good news is that you may not need to look any further than your kitchen pantry. Baking soda, that handy multi-purpose ingredient, can potentially come to the rescue.

But before you start sprinkling it into your favorite kicks, let’s consider whether baking soda is effective in deodorizing shoes.

Can I Use Baking Soda To Deodorize My Shoes?

What is Baking Soda?

Baking soda, sodium bicarbonate, is a white crystalline powder commonly used in baking and cooking. It has a slightly alkaline taste and can also be used for various cleaning and deodorizing purposes. Baking soda is a versatile household ingredient that is readily available and affordable.

Chemical Composition

Chemically, baking soda comprises sodium, hydrogen, carbon, and oxygen. Its chemical formula is NaHCO3, which means it consists of one sodium atom (Na), one hydrogen atom (H), one carbon atom (C), and three oxygen atoms (O). When baking soda is exposed to heat or an acidic environment, it undergoes a chemical reaction known as decomposition, producing carbon dioxide gas, water, and a residue of sodium carbonate.


Baking soda has a wide range of uses beyond cooking. In addition to being a popular ingredient in baked goods, it is also widely used for cleaning and deodorizing purposes. It is known for neutralizing odors, absorbing moisture, and inhibiting bacterial growth. Baking soda can be used to freshen up various items in your home, including shoes.

How Does Baking Soda Deodorize?

Baking soda is an effective deodorizer because it neutralizes odors, absorbs moisture, and inhibits bacterial growth.

Neutralization of Odors

One of the critical reasons why baking soda is so effective at deodorizing is its ability to neutralize odors. Many odors, such as those caused by sweat or bacteria, are acidic. Baking soda, being alkaline in nature, can neutralize these acidic odors by reacting with them. This chemical reaction helps to eliminate unpleasant smells and leave your shoes smelling fresh.

Absorption of Moisture

Moisture can contribute to the growth of bacteria and the development of odors. Baking soda has excellent moisture-absorbing properties, effectively reducing moisture levels in your shoes. Baking soda helps keep your shoes dry and odor-free by absorbing excess moisture.

Inhibiting Bacterial Growth

Bacteria thrive in warm, moist environments, often found inside shoes. Baking soda can help inhibit the growth of bacteria by creating an unfavorable environment for them. Its moisture-absorbing properties and alkaline nature make it difficult for bacteria to survive and multiply. By reducing bacterial growth, baking soda helps to eliminate the source of unpleasant odors.

Preparing Your Shoes for Deodorizing

Before using baking soda to deodorize your shoes, it is essential to prepare them adequately to maximize effectiveness.

Clean and Dry Your Shoes

Start by thoroughly cleaning your shoes to remove dirt, debris, or odor-causing substances. Use a mild soap and water solution or a shoe cleaner specifically designed for the material of your shoes. Scrub the surfaces gently with a soft brush or cloth to remove any stubborn stains or odors. After cleaning, allow your shoes to dry completely before proceeding with the deodorizing process.

Remove Insoles and Laces

To ensure that baking soda reaches all areas of your shoes, it is recommended to remove the insoles and laces if possible. Insoles can harbor bacteria and odors, so removing them allows for better airflow and deodorization. Similarly, removing the laces allows you to reach the shoe’s tongue and other hidden areas, preventing any lingering odors.

Methods of Using Baking Soda for Shoe Deodorizing

You can use several methods to deodorize your shoes using baking soda. Choose the best method for you and the type of shoes you have.

Sprinkling Baking Soda Directly in Shoes

The simplest method is to sprinkle baking soda directly into your shoes. Start by generously sprinkling baking soda into each shoe, ensuring it covers the entire interior. Gently shake the shoes to distribute the baking soda evenly. Leave the baking soda in the shoes for a few hours or overnight, allowing it to absorb odors and moisture. Once the desired time has elapsed, shake out the excess baking soda and replace the insoles and laces if necessary.

Creating Baking Soda Sachets

You can create baking soda sachets if you prefer a more controlled application. Fill small cloth or mesh bags with a handful of baking soda and tie them securely. Place one sachet inside each shoe and leave them for a few hours or overnight. The sachets will release the baking soda slowly, allowing it to absorb odors effectively. After the designated time, remove the sachets, shake out any remaining baking soda, and reinsert the insoles and laces.

Using Baking Soda with Socks or Shoe Inserts

Another option is to use baking soda with socks or shoe inserts. Sprinkle enough baking soda onto a pair of clean socks or inserts specifically designed to hold baking soda. Insert the socks or shoe inserts into your shoes and leave them for a few hours or overnight. The baking soda will absorb odors and moisture while remaining contained within the socks or inserts. Remove the socks or inserts, discard any remaining baking soda, and replace the insoles and laces.

Deodorizing Specific Types of Shoes

Different shoes may require slightly different approaches to deodorizing with baking soda. Here are some tips for deodorizing specific types of shoes:

Leather Shoes

To deodorize leather shoes, follow the general methods mentioned earlier. However, be cautious when using baking soda directly on the leather surface, as it may have a drying effect. Consider using a smaller amount of baking soda or placing it in a sachet to prevent direct contact with the leather. Additionally, after removing the baking soda, wipe the shoes with a soft cloth and apply a leather conditioner to maintain quality.


Sneakers often require more intensive deodorization, especially if worn for athletic activities. Before applying baking soda, remove any removable insoles and laces. Scrub the sneakers gently with baking soda and water to remove stubborn odors and stains. Rinse off the mixture, allow the sneakers to dry completely, and then proceed with the general deodorizing methods.

Athletic Shoes

Similar to sneakers, athletic shoes may have accumulated more odor-causing bacteria due to vigorous physical activities. Clean the shoes thoroughly, removing the insoles and laces. Consider using an antibacterial soap or solution specifically designed for athletic shoes to eliminate microorganisms effectively. Once clean and dry, proceed with the general deodorizing methods using baking soda.

Work Boots

Work boots often endure harsh conditions and may develop more pungent odors. Clean the boots thoroughly, ensuring that all dirt and debris are removed. Consider soaking the work boots in a mixture of baking soda and water for a few hours for stubborn odors. Rinse off the mixture, allow the boots to dry completely, and proceed with the general deodorizing methods.

Canvas Shoes

Canvas shoes are typically less durable and more prone to odor retention. Start by cleaning the shoes thoroughly and removing the insoles and laces. Scrub the canvas surfaces gently with baking soda and water to eliminate stubborn odors. Rinse off the mixture, allow the shoes to dry completely, and proceed with the general deodorizing methods.

Additional Tips for Using Baking Soda

To maximize the effectiveness of baking soda for shoe deodorizing, consider the following additional tips:

Alternate with Other Deodorizing Agents

While baking soda is highly effective at eliminating odors, it can be beneficial to alternate its use with other deodorizing agents. Some options include activated charcoal, coffee grounds, or cat litter. Each of these substances has unique properties that can complement the odor-fighting abilities of baking soda. Place the alternate deodorizing agents in your shoes for a designated period, then remove and replace them with baking soda, and vice versa.

Leave Baking Soda on Overnight

Consider leaving the baking soda in your shoes overnight for optimal deodorizing results. This extended period allows the baking soda ample time to absorb odors and moisture thoroughly. However, a few hours can still provide noticeable results if you are in a hurry or prefer a shorter treatment period.

Regular Maintenance

Establish a regular maintenance routine for your shoes to prevent odors from returning. This includes keeping them clean, allowing them to dry completely after each use, and periodically deodorizing them with baking soda or other suitable agents. You can prevent odors from becoming a persistent problem by consistently practicing good shoe hygiene.

Potential Risks and Precautions

While baking soda is generally safe for shoe deodorizing, there are a few potential risks and precautions to remember.

Allergic Reactions

Some individuals may be sensitive or allergic to baking soda. If you experience any allergic reactions, such as skin irritation or respiratory problems, discontinue use immediately. If you have a known allergy to baking soda, it is best to avoid using it for shoe deodorizing.

Avoiding Overuse

Using excessive amounts of baking soda in your shoes can have a drying effect, especially on certain shoe materials. Using a reasonable amount of baking soda is essential, and avoiding leaving it in your shoes for extended periods without cleaning or airing them out properly. Additionally, regularly check the condition of your shoes and discontinue deodorizing with baking soda if you notice any adverse effects on the materials.

Alternatives to Baking Soda for Shoe Deodorizing

While baking soda is a popular choice for shoe deodorizing, there are alternative options you can explore.

Activated Charcoal

Activated charcoal is another effective deodorizer that adsorbs odorous particles and toxins. It has exceptional odor-absorbing properties and can be used similarly to baking soda. Place a few pieces of activated charcoal in your shoes overnight, then remove and replace them with fresh ones as needed.

Coffee Grounds

Used coffee grounds can be repurposed as a deodorizer for your shoes. Fill old socks or small cloth bags with coffee grounds and place them inside your shoes. The coffee grounds will absorb odors and leave a pleasant coffee aroma behind. Replace the coffee grounds regularly to maintain their effectiveness.

Cat Litter

Cat litter can be used as a shoe deodorizer, particularly the non-clumping kind. Fill a pair of clean socks with cat litter and place one sock in each shoe. The cat litter will help absorb moisture and eliminate odors. Replace the cat litter regularly to prevent the growth of bacteria.

Frequently Asked Questions

How often should I deodorize my shoes?

The frequency of shoe deodorization depends on several factors, including odor intensity, use frequency, and individual preference. As a general guideline, deodorize your shoes with baking soda or other suitable agents every 1-2 weeks or as needed. You may need to deodorize more frequently if you notice persistent odor issues.

Can I use baking powder instead of baking soda?

While baking powder and baking soda are similar in some ways, it is best to use baking soda specifically for shoe deodorizing. Baking powder contains additional ingredients, such as cream of tartar or cornstarch, which may not be beneficial for deodorizing purposes.

Using baking soda on dry shoes is generally recommended for maximum effectiveness. If your shoes are wet, allow them to dry completely before applying baking soda. Moisture can hinder the absorption and deodorizing properties of baking soda.

How long does it take for baking soda to deodorize shoes?

The time it takes for baking soda to deodorize shoes can vary depending on factors such as the level of odor and moisture present. Leaving baking soda in your shoes for a few hours or overnight is typically sufficient to notice a significant improvement in odor.


Baking soda is a versatile, affordable household ingredient that can effectively deodorize your shoes. Its ability to neutralize odors, absorb moisture and inhibit bacterial growth makes it an excellent choice for keeping your shoes smelling fresh.

By following the proper methods of preparing your shoes and using baking soda correctly, you can enjoy odor-free footwear and maintain good shoe hygiene.
