Mould isn’t just an eyesore; it can be a serious threat to your health. When left untreated, mould can cause health problems beyond respiratory issues and allergies. It can also lead to eye and skin irritation, and emerging evidence links living with mould to negative mental health effects such as increased anxiety or stress due to poor living conditions and health worries. These issues add to the risks mould poses, especially for vulnerable groups such as children, older adults, and those with weakened immune systems.
In this blog post, we’ll explore the key health risks associated with mould and provide practical DIY methods for safely removing it from walls, ceilings, and silicone surfaces, helping you create a cleaner, healthier home environment.
Understanding Mould and Its Health Risks
Mould thrives in damp and warm conditions, appearing on surfaces like wood, paper, and fabric. When mould spores are inhaled, they can lead to allergic reactions and respiratory issues, particularly in individuals with asthma or a weakened immune system. Common symptoms include coughing, sneezing, skin rashes, and, in severe cases, trouble breathing.
Long-term exposure to mould can result in chronic respiratory conditions and sinus infections. For example, a study revealed that over 17% of people exposed to mould reported persistent respiratory problems. Thus, addressing mould issues quickly and effectively is vital to maintaining a healthy home environment.
DIY Methods to Clean Mould from Walls
Removing mould from walls can be simple with the right tools and solutions. Here are some practical DIY methods:
1. Vinegar Solution
Vinegar is a natural disinfectant that can kill about 82% of mould species. Here's how to use it:
Ingredients: White vinegar and a spray bottle.
Instructions: Pour undiluted white vinegar into a spray bottle and spray it directly onto the mouldy area. Let it sit for at least an hour before wiping it away with a damp cloth.
2. Baking Soda Paste
Baking soda is another effective mould remover that is safe for many surfaces.
Ingredients: Baking soda, water, and a spray bottle.
Instructions: Mix one-quarter of a tablespoon of baking soda with water in a spray bottle. Shake well and spray the mix on the affected area. Scrub with a brush, rinse with water, and let it dry.
3. Hydrogen Peroxide
Hydrogen peroxide is a powerful antifungal and antibacterial agent.
Ingredients: 3% hydrogen peroxide and a spray bottle.
Instructions: Spray the hydrogen peroxide directly onto the mouldy surface and let it sit for about 10 minutes. Scrub the area, then wipe it clean with a damp cloth.

DIY Methods to Clean Mould from Ceilings
Ceilings can often be neglected when it comes to mould cleaning. Here’s how to address mould on ceilings effectively:
1. Bleach Solution
Bleach is a strong mould killer, but use it carefully.
Ingredients: Bleach and water.
Instructions: Mix one cup of bleach with a gallon of water. Using a sponge or cloth, apply the solution to the mouldy area. Allow it to sit for about 15 minutes before rinsing with water.
2. Essential Oils
Certain essential oils, like tea tree oil, have antifungal properties.
Ingredients: Tea tree oil and water.
Instructions: Mix one teaspoon of tea tree oil with one cup of water in a spray bottle. Spray the mixture on the affected area and leave it to dry. The smell will fade while effectively combating mould.
DIY Methods to Clean Mould from Silicone
Silicone sealants in bathrooms and kitchens often attract mould due to constant moisture. Here’s how to clean them:
1. Vinegar and Baking Soda
This combination works wonders for cleaning mould from silicone.
Ingredients: White vinegar, baking soda, and a scrub brush.
Instructions: Spray the silicone with vinegar and let it sit for a few minutes. Then, sprinkle baking soda over the area and scrub with a brush. Rinse with water for a fresh finish.
2. Rubbing Alcohol
Rubbing alcohol can also be effective for killing mould on silicone.
Ingredients: Rubbing alcohol and a cloth.
Instructions: Soak a cloth in rubbing alcohol and apply it to the mouldy silicone. Allow it to sit for about 30 minutes before wiping it clean.

Steps to Prevent Mould Growth
Once you’ve successfully removed mould, it’s crucial to prevent its return. Here are effective prevention strategies:
Control Humidity: Keep indoor humidity levels below 60%. You can achieve this by using dehumidifiers and ensuring proper ventilation. A long-term study found that homes with controlled humidity levels saw a 50% reduction in mould growth.
Fix Leaks: Repair any leaks in roofs, walls, or plumbing promptly to prevent moisture from accumulating.
Regular Cleaning: Clean areas prone to mould, such as bathrooms and kitchens, regularly using the methods mentioned above.
Consider Mould-Resistant Products: Use mould-resistant paints and sealants in moisture-prone areas, which can decrease mould incidence by up to 70%.
Safeguarding Your Home and Health
Mould can be a serious health risk, but by employing these DIY methods, you can effectively clean and protect your home from mould growth. Taking preventive measures helps ensure your living environment remains safe and healthy.
Caring for your home does not have to be overwhelming. With a bit of effort and the right techniques, you can effectively keep mould at bay, creating a healthier living space for you and your family. Remember, a proactive approach today means a safer, more comfortable home tomorrow.
