What Is Mold?

Mold is a type of fungus that grows in damp and humid environments. It thrives on organic materials such as wood, fabric, and drywall. Mold spores are microscopic and can easily spread through the air, making it important to promptly address any signs of mold growth.

How to Remove Mold With Rubbing Alcohol

Rubbing alcohol, also known as isopropyl alcohol, is an effective mold removal agent. It kills mold by breaking down its cell walls and drying it out. To use rubbing alcohol for mold removal, simply pour it into a spray bottle and apply it directly to the affected area. Allow it to sit for a few minutes before scrubbing away the mold with a brush or cloth. Repeat the process until all visible mold is gone.

How to Remove Mold With Vodka

Vodka is another alcohol-based solution that can be used to remove mold. Its high alcohol content makes it effective at killing mold spores. To use vodka for mold removal, fill a spray bottle with vodka and spray it onto the moldy surface. Allow it to sit for about an hour before wiping it away with a clean cloth. The alcohol in the vodka will kill the mold and help prevent further growth.

Pros and Cons of Using Alcohol to Remove Mold

Using alcohol to remove mold has several benefits. It is a natural and non-toxic solution that is safe to use around children and pets. Alcohol also evaporates quickly, which helps to prevent moisture buildup that can lead to mold growth. However, alcohol may not be as effective on porous surfaces and may not completely eliminate mold spores.

Why Bleach Does a Good Job Removing Mold

Bleach is a common household chemical that is often used for mold removal. It is highly effective at killing mold and removing stains. Bleach works by chemically altering the proteins and structure of mold, making it unable to grow or spread. To use bleach for mold removal, mix one bleach with three parts water and apply it to the affected area. Allow it to sit for about 15 minutes before scrubbing away the mold. Be sure to wear protective gloves and ensure proper ventilation when using bleach.

Tips for Preventing Mold

Preventing mold growth is essential for maintaining a healthy home environment. Here are some tips to help prevent mold:

  1. Keep humidity levels in your home below 50 percent.
  2. Use exhaust fans in bathrooms and kitchens to reduce moisture.
  3. Repair any leaks or water damage promptly.
  4. Ensure proper ventilation in your home.
  5. Clean and dry any wet materials within 24-48 hours.

Other Recommended Maintenance

Now that you know about alcohol that kills mold, there are some other areas of maintenance.  One of those is how to get rid of mold in the basement.  This is done by using vinegar and baking soda.  However, it is also important to find out why the mold is there and take care of the issue.

Next, sometimes we wonder if heat can kill mold.  The good news is yes, if it is extreme heat or extreme cold can kill most mold spores.

Lastly, while you are looking to see if there is mold in your home, you may also be concerned if your well water has fluoride.  Your well water does have fluoride and the amounts vary according to the concentration in groundwater.

When to Contact a Professional

While many cases of mold can be addressed using DIY methods, there are situations where it is best to contact a professional mold remediation specialist. These include:

  1. If the mold covers a large area (greater than 10 square feet).
  2. If the mold is causing severe health issues or allergic reactions.
  3. If the mold is growing in areas that are difficult to access or clean.

A professional mold remediation specialist has the knowledge and equipment to effectively remove mold and ensure that it does not return.


Mold can be a persistent and damaging problem in homes.
