Mould can look ugly and smell unpleasant, but it doesn’t have to ruin your home if you’re willing to get on your hands and knees with some mould killer and elbow grease. Follow these easy steps on how to remove mould from walls and ceilings, and you’ll be on your way to eliminating this pesky problem in no time. Make sure to wear gloves, goggles, and old clothes when working with bleach or any other harsh cleaning chemicals!
What Is Mould?
Mould is a fungus that feeds on organic material such as cellulose. You can find mould almost anywhere: in your yard, in your basement, inside your home—even on food. There are thousands of different types of mould, most of which you won’t recognize. Some types produce allergens and can even cause infections or diseases.
Good news: if you see or smell mould growth in your home, it’s usually easy to remove with basic cleaning tools and methods.
Bad news: removing mould isn’t always easy—and sometimes requires hiring a professional for removal and cleanup, so you don’t accidentally expose yourself to unhealthy mould spores or spread them around your home after they’re removed.
What Caused Mould To Appear On Your Ceiling?
The most common cause of mould on your ceiling is inadequate ventilation in your home. Your home’s HVAC (heating, ventilation, and air conditioning) system draws air into it; that air needs somewhere to go. If you don’t have adequate ducting or vents that allow that warm, moist air to escape your house, it will stay in there.
Method 1: Mould Removal with Bleach
To use bleach, you will need a spray bottle that is capable of delivering a mist. Fill your spray bottle with 1 part bleach and 10 parts water. Mix well until all of the bleach has dissolved in water.
Spray on surfaces with mould growth and let it sit for 15 minutes or more before wiping clean with a damp cloth. Make sure you do not rinse anything away because rinsing can spread mould spores throughout your home and cause even more damage than just letting it be.
Method 2: Mould Removal with Vinegar
Vinegar is a good choice for anyone looking for an organic solution. Add 1/2 cup of white vinegar to 1 gallon of water, mix well, and then pour into a spray bottle. Spray directly onto mouldy surfaces.
Wait 15 minutes, and then scrub clean with a brush or sponge. Use multiple applications if necessary for tougher stains. The smell of vinegar should disappear within two hours or less after application, but keep windows open or use fans in rooms that have been treated to remove any lingering odours. Do not use vinegar on marble, as it will etch your surface’s finish!
Dangers and Things to Avoid During Cleaning
Unless you have advanced training in remediation, it’s never a good idea to try removing mould on your own. The dangers include but are not limited to allergies, respiratory problems, worsening of pre-existing health conditions, lack of proper training that leads to serious damage. You must call professionals if you suspect any sign of mould growth. Their expertise could prevent major repair costs or structural damage down the road. If you don’t know who can help you with mould removal but suspect an issue, start with your local municipality (city hall). They will likely be able to point you in the right direction for remediation services.
Tips to Keep Your Ceiling Mould-Free
- You first want to remove any mouldy ceiling tiles, then wash them with mild soap or mould remover detergent. You can use a soft-bristled brush or another scrubbing tool, but be careful not to damage surrounding tiles with abrasive chemicals or materials—or you’ll have more problems on your hands!
- If using bleach mould killer or other strong cleaning agents, make sure you leave time for them to air out before turning your fans back on—leaving bleach-filled air in an enclosed space for too long can cause respiratory issues like coughing, sneezing, irritation of mucous membranes, runny nose and watering eyes.
