How To Remove Black Mould

It’s unsightly, odorous and, even more alarmingly, toxic – so it’s of crucial importance that you know how to remove black mould. But before you dive head first into tackling the issue, a bit of background knowledge goes a long way towards helping you to remove mould safely, efficiently and effectively.

In this blog, we help you get to grips with black mould so you can get rid of it, and even prevent it from returning in the future.

What is black mould?

Often found in the form of dark spotty patches around the home, black mould is a kind of microfungus that grows in the presence of moisture. It’s slimy to the touch, uneasy on the eye, and potentially dangerous when left untreated. It’s safe to say that there is no place for mould growing in your home.

What causes black mould?

Condensation is the most likely culprit. When water vapour has nowhere to go, it collects on surfaces and then condenses when the surface is at a lower temperature than the moist air. These are the damp conditions where black mould thrives.
Windows, walls, bathrooms, crevices and seals are all black mould hotspots. As well as cold surfaces, high humidity and a lack of airflow also explain why these locations are more susceptible. So, it comes as no surprise that poor ventilation contributes to the problem too.

Is black mould dangerous to health?

How long you leave black mould to fester determines just how dangerous it is, but the bottom line is that mould spores are toxic. Related health problems can include difficulty breathing, nausea and skin irritation. And, while uncommon, it can even be fatal.

How to get rid of black mould

There are various substances that can help remove black mould. These include bleach-based mould wash, white vinegar, tea tree oil, hydrogen peroxide and baking soda. All methods should be executed with a damp cloth, using rubber gloves, safety goggles and a face mask to protect yourself.

How to remove black mould from walls

Using a spray bottle, apply either mould wash, tea tree oil solution (two teaspoons of oil and two cups of water) or vinegar (neat for heavy mould, equal parts with water otherwise) to the affected area and wipe clean.
How to remove black mould from fabric
