My Habitat Mould Master 5L is a bulk refill size designed for tackling visible mould and mildew on common household surfaces where damp tends to build up. It’s a practical pick for busy bathrooms, laundries, kitchens, caravans, and coastal homes — anywhere condensation and poor airflow can turn small spots into a recurring job.

The 5L format makes it easy to keep a smaller bottle topped up for quick, consistent maintenance. Many people find mould is less of a “one-and-done” problem and more of a routine: treat the area, wipe clean, and then help the surface stay drier (better ventilation, dehumidifying when needed, and drying wet zones faster). Used this way, a refill size can be a cost-effective and lower-waste option compared with buying multiple small bottles over time.

For day-to-day use, focus on the usual hotspots: shower corners, grout lines, silicone edges, window tracks, behind bathroom items, and cupboard back panels. If the surface is delicate or you’re unsure (natural stone, unsealed timber, specialty paint finishes), a quick patch test is a smart move before wider use.
