How to remove mould around your home

How to remove mould in your home

Seeing a shelf gathering dust or a spiderweb in the corner is a cleaning job that’s easily dealt with. By contrast, the sight of a suspicious looking black patch somewhere around the home can be more troublesome.

At first glance, you wonder if it is simply an area of dust or dirt that has accumulated. But on closer inspection, you realise that you’re dealing with an area of mould.

This can often be concerning, and mould is not something you can ignore or put off. Along with being unsightly, mould has the potential to be extremely unhealthy and could compromise the wellbeing of your household.

It could also be indicative of a much more serious issue below the surface, which will need to be investigated in due course. High humidity, condensation and water leaks can all cause mould to accumulate on ceilings and surfaces in any room of the home.

The DIY approach to removing mould

Dealing with rudimentary patches of surface mould is relatively easy. But the technique outlined below will not address the issue that caused mould to form in the first place.

After carrying out the mould removal, you will need to work out how it got there and make the necessary corrections accordingly. For example, you may need to think about installing an extractor fan or improving air circulation in some other way.

The tools and supplies you will need to get rid of surface mould are:

  • Bucket
  • Gloves
  • Mask
  • Bleach 
  • Water
  • Cloths
  • Ladder

Remember wear the appropriate PPE. Protect your eyes, airways and skin from potential chemical burns, when handling bleach or any similar cleaning product.

Step 1: Prepare the diluted bleach solution

Applying neat bleach to your walls could be damaging and cause additional issues. Instead, make a diluted solution with a 10:1 ratio – 10 parts water to every one part bleach. Make sure the space in which you are working is adequately ventilated.

Step 2: Clean the surface

Soak a cloth in the diluted bleach solution while wearing rubber gloves and squeeze it out until it is just damp.

Before going ahead with the mould removal, it is advisable to spot-test the bleach solution in a hidden corner to see how it reacts with the surface.

If the test doesn’t produce any issues, you can begin wiping the mould away using a gentle circular motion, without pressing too hard so as to protect the surface from further damage. Rinse the cloth on a regular basis and mix a new batch of bleach if the solution you are using becomes excessively dirty.

Try to avoid excessive runoff or drips when treating the affected area, which could harm the wall below.

Step 3: Rinse the surface

When you are satisfied that the mould has been removed in its entirety, take a bucket of clean water and give the surface a careful rinse. Use the same gentle circular motions and a clean cloth to get rid of any excess bleach that may have accumulated on the wall.

Step 4: Dry carefully

Finally, take another dry cloth and gently dab it onto the wall or ceiling to absorb as much excess moisture as possible. You can then leave the wall to dry and check whether you fully removed the mould – repeating the process again if necessary.
