Treating The Mold

In order to kill the spores, disinfect the affected area, remove stains and deodorize the air, you will need a cleaning agent. You can use different cleaning agents to treat the mold.

Detergent Solution

The borate-based solution is used to target the severe mold problem. It also reduces the likelihood that the mold will grow again. You can use any borate-based detergent like Borax to prepare the solution. Borax is a mineral-based detergent that kills mold and removes the bad odor from the air.

Prepare a strong solution of Borax and wash the affected area with the solution. Next, you can use a brush or sponge to remove the mold stains from the walls and ceilings. Finally, rinse off the solution from the walls and let the ceiling dry.

Also, it produces pungent fumes that can cause respiratory issues and eye irritation. Therefore it is recommended to wear thick plastic gloves, safety goggles, and a face mask. Plus, keep the windows open and switch on the exhaust fan to avoid the toxic fumes of bleach.

To make a solution add one cup of bleach to two cups of water. Carefully apply the solution to the affected area. Use a soft brush to remove the mold stains. Rinse the solution with clean water and let it dry. Respray the solution on the affected area and leave it to dry. Regularly spray the bleach solution to prevent the mold from growing again.

Cleaning the mold is not sufficient as mold will come back in warm weather and excessive moisture. However, you can control the conditions like temperature and moisture to get rid of mold problems permanently.

Damp and humid conditions favor mold growth. A dehumidifier is an electronic device that is used to maintain the humidity level in the air. Installing this device in the bathroom will help in creating less favorable conditions for the molds. Also, it will reduce the odor produced by mold spores.

Fix The Leakages

Leakages in the walls and ceiling are a major cause of the moisture and growing molds. Therefore it is crucial to fix the leakage if you want to remove the old permanently. Carefully examine the roof and ceiling. If you find a crack or observe water seeping through the roof, go for an immediate repair.

Get Proper Ventilation and Sunlight

The mod growth is multiplied if there is no proper ventilation for air circulation in the bathroom. Usually, bathrooms have small windows that are not enough to maintain the proper ventilation. Therefore it is critical to install an exhaust fan for a proper inflow and outflow of air. Also, keep the doors and windows open to proper the inflow and outflow of the air. Open the windows during the daytime to allow the sunlight to come in.

Get Proper Insulation

Proper insulation of the walls also prevents mold from growing inside. In summers, there is a huge temperature difference on both sides of the ceiling. This temperature difference leads to condensation inside, making the conditions favorite for molds. Condensation occurs only when there is poor insulation in the walls and ceilings; therefore, it is critical to improving the ventilation in the ceiling and walls.

Little things To Do

Do not hang wet towels and damp clothes inside the bathroom. Also, keep the wet cleaning tools like brushes and sponges outside the bathroom. Carefully wash the sponges and tools used in mold cleaning. Otherwise, you will transfer the mold to other areas of the home. Try to keep the bathroom dry as much as possible.
