Question: What is the most cost effective treatment that can be applied to remove mould from affected areas?
Answer: Clean the mould affected area down with warm soapy water.
You can clean mould down with warm soapy water. There is the theory that you can use an 80/20 vinegar water mix. You can also use mould killers.
You want to be removing the mould, not just removing the colour of the mould or the mould may still be there. So warm soapy water is really the best for this. Get a hot bucket of soapy water and you can just wet wipe it down.
Try to avoid spraying with a trigger spray. If there are mould spores and you spray it with anything it can cause the mould spores to become airborne and move around and that’s when you can breathe them in.

The one thing we’d add from experience treating mould in strata apartments across the Illawarra: cleaning the surface, however you do it, only solves half the problem.
Mould can’t grow without moisture, so if there’s an underlying cause (condensation, poor ventilation, a leak, or shared building issues common in strata), the mould will keep coming back no matter how well the area is wiped down.
For a small, isolated patch in a well-ventilated room, warm soapy water is a perfectly reasonable first step. For anything recurring, widespread, or in common property, it’s worth identifying the moisture source first, as the cheapest fix long-term is usually the one that stops it returning.
Worth noting too that in strata, responsibility for the cause (say, building waterproofing versus in-lot ventilation) can affect who wears the cost, so a proper assessment can save some back-and-forth down the track. We always provide out customers will a report which they can then use to document for proof down the track too.
