3- Killing Mold

Tea Tree oil is one of the best ways to kill mold in your kitchen or any other areas that always have moisture. Usually, people prefer bleach or vinegar, but tea trees have antioxidant properties that help kill mold and mildew instantly. 

You need to add other chemicals, as only spraying tea tree oil directly to the mold will not be very effective.

What is Mold?

Mold is a fungus that makes its home in moist areas such as wet walls, kitchens, and bathrooms. Mold and Mildew are resistant to physical and chemical attacks. So it seems that only tea tree oil cleaning can solve this problem. 

Mold can cause health issues if it’s not cleaned off properly before it gets on other materials. 

Even if mildew is not a serious problem for you, its presence may lead to issues that may require immediate action as it has toxic gas emissions, which can cause health problems like asthma or bronchitis. 

Where To Find Tea Tree Oil

Tea Tree Oil (TTO) can easily be found in most pharmacies and health food stores. Moreover, there are a lot of recipes for homemade tea tree oil that you can make yourself. It is very effective and has many good properties for cleaning and disinfecting the surfaces in the home. 

For example, you can use it as a natural pesticide against insects such as mosquitoes. But it should be used only on external surfaces because it may cause skin irritation or damage some materials inside the house, such as wood.

Nowadays, people like tea tree oil so much because they know that they can use a lot of advantages. For example, you can use it not only for mold cleaning but also for other purposes. 

You can wash your hair or use it as a moisturizer to keep your skin healthy. So if you have a problem with mildew/mold, then Tea Tree Oil (TTO) will help you with this problem.

Advantages Of Using Tea Tree Oil To Kill Mold

Tea tree oil is a popular ingredient in shampoos and cleaners because of its antifungal properties. It specifically attacks the spore-forming cells of the mold, which usually prevents it from reproducing. 

Therefore, tea tree oil is used to make antifungal products and disinfectants. The antifungal properties of tea tree oil are due to its terpene content, which includes terpinen-4-ol and alpha-terpineol.

These give tea tree oil its distinctive aroma while also providing the antifungal activity that makes it so useful. Tea Tree Oil (TTO) can also be used as a fungicide in areas where mold or mildew will not affect your health or cause an allergic reaction.

You can use 50 percent tea tree oil to kill mold and mildew, but it should be diluted with normal water. It helps in preventing drying out the wood or tile. 

When you kill mold with tea tree oil, you get a bright white finish that will never yellow over time as bleach does.

Note: When you use tea tree essential oil to deal with mold, it’s important to know that this may not eliminate all the mold in your home. 

For example, suppose a crack in your foundation allows water in, thus causing the mold. In that case, you’ll need to get this repaired or replaced as soon as possible. 

There may be some moisture still present, but you can try adding Tea Tree Oil and let it sit for a day or two before you come back and clean it up.

Although we hope that this will be enough to kill the mold completely with natural ingredients, if you are trying to get rid of mold at all costs, you will probably need a professional to assess the situation and perform some cleaning procedures. 

Even if there is no visible mold on the surface you’re cleaning on, it is still important that you have a professional checkup of all surfaces in your home as part of their inspection.

  • Allow for a 15-minute rest period.
  • Mix the spray bottle before spraying the solution onto the mold you’re trying to get rid of. Allow 18-20 hours for it to dry before cleaning it away with a clean cloth.
