How to Treat a Mold Infestation on Wood With Borax 20 Mule Team Powder


Mold is a common problem in many households, especially in humid and damp areas. Not only does it look unsightly, but it can also cause health problems if left untreated for too long. If you’re looking for an effective and natural way to get rid of mold, Borax might just be the solution you’ve been looking for. In this article, we’ll discuss how to use Borax to kill mold and prevent it from coming back.

What is Borax?

Borax is a naturally occurring mineral that is commonly used as a cleaning agent. It’s a white powder that dissolves easily in water and is often used as a laundry detergent booster. Borax is also known for its mold-killing properties and is a popular alternative to chemical-based mold removers.

How Borax Works to Kill Mold

Borax works by changing the pH level of mold cells, making it impossible for them to grow and reproduce. When Borax is applied to mold-infested areas, it seeps into the cells and dehydrates them, ultimately killing the mold.

How to Use Borax to Kill Mold

Before you begin, make sure you wear protective gloves and a mask to avoid inhaling the Borax powder. Here’s how to use Borax to kill mold:

Step 1: Mix Borax with Water

Mix 1 cup of Borax with 1 gallon of hot water. Stir the mixture until the Borax dissolves completely.

Step 2: Apply the Solution to Mold-Infested Areas

Using a spray bottle or a sponge, apply the Borax solution to the mold-infested areas. Make sure you cover the entire surface and let the solution sit for at least 30 minutes.

Step 3: Scrub the Infested Area

Using a scrub brush, scrub the mold-infested area until all the mold is removed. Rinse the area with clean water and dry it thoroughly.

Preventing Mold Growth with Borax

Once you’ve successfully removed the mold, it’s important to take preventative measures to ensure it doesn’t come back. Here are some tips:

Keep the Area Dry

Mold thrives in damp environments, so it’s important to keep the area dry. Use a dehumidifier to reduce the humidity level in the room and ensure proper ventilation.

Use Borax as a Preventative Measure

Using Borax regularly can help prevent mold growth. Simply mix 1 cup of Borax with 1 gallon of water and use it to clean surfaces prone to mold.

Fix Water Leaks

Water leaks can cause mold to grow, so it’s important to fix any leaks as soon as possible. Check for leaks in pipes, roofs, and windows, and repair them immediately.
