Mold can wreak havoc on your home. It often appears because of excessive moisture, and sometimes it starts growing in places where you would least expect it – like grout or under the sink. Many people have resorted to bleach to get rid of it but have been left with an overwhelming odor that has made their space even more unpleasant to use. 

A few years ago, I built my home. We upgraded the garage into a bedroom and built on a new bathroom. Unfortunately, there was not sufficient air circulation above the shower to let it dry. I started to notice mold growth soon after.

How to clean mold with vinegar and baking soda

I would scrub away the mold, from above and inside the shower constantly but couldn’t seem to kill it, even on the surface, or keep it clean.

Knowing how dangerous black mold can be, this was something I knew I had to get rid of quickly. I began researching ways to resolve this issue.

I didn’t want to spend unnecessary money or use caustic materials in my home, so I searched for natural, effective ways to fix this problem. Fortunately, found out that I can clean mold with hydrogen peroxide, vinegar, and baking soda.

Using Vinegar and baking soda is the most effective natural way for removing mold in your home. To do this, mix vinegar with baking soda in the spray bottle. Spray your mixture heavily onto the place where you have mold and allow it to sit for an hour before scrubbing it away.

Read on and find out the exact steps on how I used it and some other useful tips for removing mold out of your home.

What Does Black Mold Look Like?

The best way to identify black mold is by its color. Other types of mold and mildew that may occur are often pink, grey, white, or brown. A region that is moist for 72 hours or more is also likely to develop black mold.

How does black mold look like?

It is very dangerous and can cause health problems in people. It can grow in moist environments, such as basements and attics, and often looks black or green.

How to Use White Vinegar to Kill Mold? 

White vinegar is one of my favorites. Is a very versatile product that can be used in a variety of ways. Mold removal is no exception.

Make Sure You Have What You Need:

  • A clean, empty spray bottle
  • White vinegar (distilled is best but any type will do)
  • A scrub brush
  • Towel or cloth
  • A bucket of clean, warm water
  • A funnel for pouring white vinegar (optional)
  • Gloves
  • A breathing mask
  • Googles

Step 1: Safety First: Make Sure To Protect Yourself 

As with any cleaning project, it’s important to take the proper safety precautions before you begin. When dealing with mold, it’s especially important to wear gloves, a breathing mask, and goggles. This will protect you from coming into contact with mold spores which can be harmful to your health.

Note: If you are exposed to mild acid for an extended period, it can harm your skin. Plus, using an N-95 mask is recommended.

Step 2: Prepare Your Solution 

For this, you’ll need a clean, empty spray bottle and distilled white vinegar. If you’re using a funnel, pour the vinegar into the bottle. If not, be very careful not to spill any as you pour it in. You can dilute the vinegar with water if you choose, but undiluted vinegar is more effective.

Brush mold away

Step 3: Soak The Moldy Area With Vinegar 

Spray the vinegar onto the spot where you see a mold problem. Make sure you spray it an inch or two beyond the area where you observe mold. This will help prevent it from spreading and will also eliminate any mold lying beneath the surface.

Let the suspected area soak in vinegar for about an hour and allow it to completely kill the spores.

Step 4: Scrub Away With A Brush

Take your scrub brush and give the area a good scrub. This will help remove any leftover residue. If the mold is particularly stubborn, you may need to let the vinegar solution sit for a little longer.

Keep a bucket of water beside and make sure to rinse your brush. If you do not rinse it often, you may leave stains and trace amounts of mold on the surface you are cleaning.

Additionally, this step may also take some time and will most likely be messy. Wearing gloves and an apron or old clothes while scrubbing is a good idea.

Pro Tip: Once you're finished scrubbing, wash your clothes with warm water. Add 1/4 cup of vinegar to your laundry to further ensure all the lingering spores are killed.

Step 5: Wipe Down Or Rinse 

Once you’re finished scrubbing, take a clean cloth or towel and wipe down the area to remove any residual vinegar. If the mold problem is particularly bad, you may need to repeat steps 3-5.

You may also rinse with clean water, but this isn’t always necessary. In some cases, it’s actually better to leave the vinegar solution on the surface to create a protective shield.

Step 6: Dry And Ventilate 

Be sure to dry the area completely before you put anything back in place. Leaving any moisture behind will only create a ripe environment for the mold to grow in the future.

Furthermore, open any windows in the room to create ventilation. This will ensure that the fumes from the vinegar don’t build up and become overwhelming.

Pro Tip: Turning on a fan or using a dehumidifier will help speed up the drying process.

How to Use Vinegar and Baking Soda to Control Mold Growth?

There are several ways to use vinegar and baking soda:

  1. Use a 1:1 ratio of water and vinegar in a spray bottle
  2. Mix equal parts of water, vinegar, and baking soda in a spray bottle 
  3. Make a paste out of the water, vinegar, and baking soda
  4. You can use straight vinegar or straight baking soda

What You’ll Need:

  • Water
  • Empty Cups
  • Vinegar
  • Baking soda
  • Spray bottle
  • Scrub brush

Using Baking Soda to Kill Mold

Baking soda is a natural antibacterial. When used alone, it can be effective at killing and preventing mold growth.

  1. Combine equal parts water and baking soda to make a paste.
  2. Apply the paste. Allow it to sit for at least 30 minutes. This will give the baking soda time to kill the mold spores.
  3. Use a scrub brush to scrub the paste into the affected surface.
  4. Use a cloth to wipe the space, then ventilate the area well to let it dry completely.

Using Baking Soda Together With Vinegar

Sometimes using vinegar solution does not remove the mold completely. Alternatively, you can use baking soda + vinegar solution for more effective results.

  1. In a cup, mix equal parts water, vinegar, and baking soda.
  2. Pour the solution into a spray bottle and shake it gently.
  3. Spray it heavily on the mold and allow it to sit for 30 -45 minutes.
  4. Use a brush to scrub away the residue

Note: if there is a strong odor and dark color to your mold, please have it assessed by a professional, for your safety.

Vinegar Or Bleach: Which Is Better to Remove Mold?

There are several ways to clean mold, but the most common and effective methods are either using vinegar or bleach. But which is better?

The answer to this question depends on a few factors:

  1. The type of mold you’re dealing with
  2. The surface the mold is growing on
  3. Your personal preference


  • Both bleach and vinegar are household products you likely already have in your home.
  • Both are affordable and effective.
  • Vinegar is a naturally antimicrobial substance that can kill 82% of mold species.
  • Bleach is also an effective mold killer. It can kill up to 99.9% of mold species.


  • Vinegar is non-toxic and safe to use around children and pets.
  • Bleach is very toxic and can cause skin irritation, respiratory problems, and other health issues. It is ineffective on a porous surface because the chlorine does not come in contact with the mold easily and hence does not kill mold spores. Moreover, bleach traps moisture inside porous materials causing the mold problem to be even worse.
  • Unlike vinegar, bleach can damage carpets and upholstery,
