1. Notes when dealing with mold on walls and ceilings
Mold often appears when there is high humidity and lack of ventilation in the house. This condition not only affects the aesthetics of the house but can also cause health problems such as asthma, allergies, and infections. Therefore, removing mold is essential.
If your walls and ceilings are affected by mold, use the following solutions to keep your living space clean and safe:
Citric acid solution
Citric acid (also known as lemon acid or sour powder) is a natural substance found in many fruits such as lemons, oranges, etc. It has the ability to effectively clean and kill mold. You can buy pure citric acid at many grocery stores or supermarkets. It is used as a natural preservative or to add a sour taste to some packaged and canned foods.

To treat mold on walls and ceilings, mix citric acid with water in a ratio of 1 liter of water to 1-2 tablespoons of citric acid. Stir until dissolved, pour the solution into a spray bottle, and spray it evenly on the moldy areas on the surface of the walls and ceilings.
Let the solution soak for about 10-15 minutes, then use a soft brush to gently scrub the moldy area and wipe it clean with clean water. Let the surface of the ceiling dry naturally, then carefully check if there is any remaining mold; repeat the process if necessary.
To prevent mold from recurring, make sure your living space is well-ventilated and has stable humidity; regularly clean and check for any new signs of mold and handle them promptly.
White vinegar
When mold starts to appear on the walls, handle it immediately by using white vinegar, which is considered an effective natural mold remover.
Mix pure white vinegar with water in a 1:1 ratio; use a spray bottle to spray this mixture on the moldy areas, and let it dry completely before wiping it with clean water.
Water and soap
Mix a small amount of soap into warm water. Use this mixture to wipe off the mold on the walls and ceilings. For stubborn mold areas, you can use a little baking soda or white vinegar to increase the effectiveness of cleaning.
Hydrogen peroxide solution
Hydrogen peroxide is a very effective mold cleaner. Mix a small amount of hydrogen peroxide with warm water, then use this solution to wipe clean.
Bleach solution
If the mold problem is severe, you can use bleach solutions such as chlorinated water to clean. However, you should be cautious as chlorine can cause skin and respiratory irritations.
Tea tree oil solution
Tea tree oil has antibacterial and antifungal properties. Mix a few drops of tea tree oil into warm water. Use this solution to thoroughly wipe off the mold on the walls and ceilings.
Notes when dealing with mold on walls and ceilings
Before starting, make sure you wear a mask, gloves, and protective glasses to protect yourself from inhaling mold spores and cleaning chemicals.
After cleaning off the mold, ensure good ventilation in the surrounding space by using a fan or dryer to help the walls and ceilings dry quickly. At the same time, find out the root cause of the problem and take preventive measures to prevent mold recurrence.
Preventing mold from appearing on walls
To prevent mold from appearing on walls, you can take the following preventive measures:
Control humidity
High humidity is one of the main factors that promote mold growth. Make sure to control the humidity in your home by using a dehumidifier or air conditioner, especially in areas such as the bathroom and kitchen.
Improve ventilation system
Ensure that your house has a good ventilation system to remove moisture and dry the air. Install ventilation fans, regularly check and clean the ventilation system.
Use a dehumidifier
If the air circulation is poor, the space inside the house can become damp and emit a musty odor. Insufficient ventilation also makes the walls prone to dampness and mold development.
In areas with high humidity, using a dehumidifier can help reduce water condensation and prevent mold growth.
Change building materials
In case you are building or renovating a house, consider using mold-resistant materials such as mold-resistant bricks and paint to reduce the risk of mold growth.
Maintain cleanliness
Regular daily hygiene and periodic inspections will help you detect and handle mold in a timely manner. Regularly clean surfaces such as walls and ceilings, especially in humid areas such as the bathroom and kitchen. Immediately wipe off water stains on the walls to prevent mold growth.
Check and repair leaks
If there are leaks or damages to the roof or plumbing system, repair them immediately to prevent water from seeping into the walls and creating conditions for mold growth.
Maintaining cleanliness and controlling humidity in the house are key factors in preventing mold from appearing on walls.
