DIY Mold Spray with Essential Oils – Easy and Non-Toxic

This natural DIY mold spray with essential oils is easy to make and effective & non-toxic to use!

For most of August and some of September the weather was miserable.

Paper and books felt soggy to the touch and I had to move a bunch of clothing to our new storage unit because it was mildewing on the closet. Then I noticed something horrifying – the back panel of our living room media console was covered with some sort of mold, inside and out! I vacuumed and cleaned it off with some sanitizing wipes.

Less than a week later, the mold was back.

That’s when I decided to make my own mold spray with essential oils and vinegar. So far, it’s worked better than the wipes I used before, which is pretty exciting!

This essential oil mold and mildew spray is pretty awesome, but it’s important you know how to use it correctly.

This spray only works as far as it can penetrate. It cannot get mold inside your walls or floorboards, for example, that it simply cannot access.

Essential oils may not be able to tackle really huge mold problems. Please call a pro if needed! 

This spray works wonderfully for maintenance cleaning, like keeping mildew at bay in your bathroom. Just spray down your shower after using it to keep it nice and clean!

According to the Lung Association, many commercial cleaners contain potentially harmful ingredients. They recommend shifting to natural cleaners, like vinegar, whenever possible. This mold/mildew cleaner is effective and healthy!

Supplies needed to make DIY mold & mildew spray

  • Glass spray bottle 
    • Please note that I photographed this with a clear bottle because it’s what I had on hadn’t when I needed it, but amber or cobalt blue bottles are much better for essential oil sprays. They keep light from degrading the oils.
  • 1 cup white vinegar
    • If you absolutely hate the smell of vinegar, you can dilute it, but your spray is far more likely to be effective if you don’t dilute the vinegar further.
  • 20 drops Melaleuca or tea tree essential oil (scroll down for more essential oils that fight mold if you don’t have tea tree oil!)
  • 5-10 drops of an additional oil like cinnamon, clove, lemon, orange, peppermint, or oregano for more mold-fighting power.
  • Protective gear like a mask, gloves, and goggles. Optional but highly recommended!

EDIT: I used to only use DoTerra oils for everything, but I’ve switched to NOW Foods oils for things like cleaning products when I can find a pure essential oil from them. Some of their oils are diluted, but they’re clearly marked, so just make sure to find the pure essential oil offerings and you’ll be okay!

Pretty easy supply list, right? I needed full strength mold spray, but if you think the smell of uncut vinegar will be too much for you, you can use 1/2 cup vinegar and 1/2 cup distilled water.

How to make and use DIY essential oil mold & mildew spray

This is so simple – are you ready?

1. Combine all ingredients in the spray bottle.

2. Shake to combine before each use.

I said it was easy!

How to use mold and mildew spray

On moldy surfaces:

1. Spray the affected area with your mold spray and let it dry fully or for at least an hour.

This allows the mold to absorb the vinegar and reach the membrane behind the fuzzy part. This membrane is the true, underlying source of the problem.

2. After an hour, spray again then wipe it down with a cloth or paper towels. Wiping down helps keep the mold spores from becoming airport.

3. Give the whole area another spray then allow it to dry completely.

For maintenance cleaning:

To keep areas like your shower clean, spray and wipe down after each use.

Spray the area, then whipe down.

There are multiple high-quality essential oil companies out there, but not all essential oils are created equal. I’ve used rando/grocery store brands in the past that were obviously very diluted. I remember one bottle of lavender oil, in particular, that needed about 20 drops to actually smell the lavender in anything!

I used to exclusively use DoTerra oils, as pictured here, but have also started using some of NOW Foods’s pure oils for cleaning products like this. Just make sure you’re using pure essential oils (no filler or fragrance oils!) and you should be fine.

Essential oils that fight mold

If you don’t have tea tree oil, there are others you can use. You can also add a few drops to boost your mold spray’s power.

Oregano oil is an incredibly potent essential oil that can help sanitize your home.

It may have anti-mold properties and studies have shown it can help eliminate germs. [efn_note]Sienkiewicz, M, et al. “[The Antibacterial Activity of Oregano Essential Oil (Origanum Heracleoticum L.) against Clinical Strains of Escherichia Coli and Pseudomonas Aeruginosa].” Current Neurology and Neuroscience Reports., U.S. National Library of Medicine, www.ncbi.nlm.nih.gov/pubmed/23484421. Gilling, D H, et al. “Antiviral Efficacy and Mechanisms of Action of Oregano Essential Oil and Its Primary Component Carvacrol against Murine Norovirus.” Current Neurology and Neuroscience Reports., U.S. National Library of Medicine, May 2014, www.ncbi.nlm.nih.gov/pubmed/24779581.[/efn_note]

Oregano oil is very “hot,” which means it can burn if topically applied undiluted. I personally wouldn’t use more than a few drops to avoid potential problems with breathing in sprayed oregano oil!

Cinnamon oil may be effective at combating mold[efn_note]Cvek, D, et al. “Growth Inhibition of Aspergillus Ochraceus ZMPBF 318 and Penicillium Expansum ZMPBF 565 by Four Essential Oils.” Current Neurology and Neuroscience Reports., U.S. National Library of Medicine, June 2010, www.ncbi.nlm.nih.gov/pubmed/20587393.[/efn_note] Again, it’s very potent so be careful!

Clove oil is another powerful oil that may help with mold problems. [efn_note]Gupta, Charu, et al. “Comparison Of Antimicrobial Activities Of Clove Oil & Its Extract On Some Food Borne Microbes.” The Internet Journal of Health, Internet Scientific Publications, 31 Dec. 2008, ispub.com/IJMB/7/1/13649.[/efn_note] Just remember, if you have a black mold problem you really should call processionals!

Peppermint, lemongrass, orange, and lemon may also kill mold/fungus and bacteria (source).

A few more thoughts about removing mold yourself:

If you have a serious mold problem please call a mold removal specialist!

Mold spores are naturally occurring in the air. Even if you get rid of mold on your furniture, as I have, it may come back later. Whenever the humidity rises, mold may make a comeback. From what I’ve read, 24-48 hours of humidity above about 60% is all the airborne spores need to take advantage of the situation!

To help keep mold at bay, consider using a cold diffuser to diffuse for a day or two after your mold clean up, and again as needed.

  • It’s very important to use a cold diffuser because heat can damage essential oils, making them ineffective.
  • Consider using a blend of oils. Look below the recipe for some for some of the best essential oils for combating mold!

    Thank you for this information. However, I have a question: can any of those essentils oils being use to remove mold, spores, etc, harm dogs?

    • Natasha October 15, 2019, 10:52

      Yes, several of the oils discussed, including tea tree oil, can be toxic to dogs. They are generally most harmful when they come into direct contact with the dog, are ingested, or are diffused into the air. You can read more about essential oil safety and dogs here: https://www.rover.com/blog/essential-oils-safe-dog/
      Many commercial household cleaners are also potentially toxic to dogs, including things like Pine Sol and even Windex!
      You could try using just vinegar to clean. It’s an effective cleaner on its own and safe.
