Solutions for stubborn mould in your home

Stubborn mould requires a targeted approach using a product specially developed and approved for mould removal. General cleaning products and home remedies are not suitable for this purpose and should not be used as alternatives. They do not address mould at its source, offer no guarantee of safe removal and can damage the surface. We therefore strongly recommend using only our HG mould removers, which have been specially developed for this cleaning task.

• Always use a mould remover suitable for the surface where the mould is present and approved for that surface.
• Follow the instructions carefully to achieve the best results.
• If in doubt, test the product first on an inconspicuous area, as some mould removers may have a bleaching effect.
• Ventilate the room well during and after cleaning.

If the mould keeps returning, it is important not just to clean but also to address the root cause of the problem. Always check the manufacturer's maintenance instructions for the surface you are treating beforehand.

Causes of stubborn mould

Stubborn mould usually does not develop without reason. By understanding the causes, you can prevent its return as much as possible. The most common causes of mould growth in the home are:

• Moisture: High humidity levels, condensation or leaks create an ideal environment for mould growth.
• Dark spots: Mould develops faster in areas with little daylight, such as corners, behind furniture or in poorly ventilated spaces.
• Poor hygiene: Surfaces that are not cleaned regularly give mould the chance to build up.
• Porous materials: Materials such as rendered surfaces, wood and grout absorb moisture, making it easier for mould to take hold.

By ventilating well, tackling moisture problems promptly and cleaning regularly, you significantly reduce the chance of stubborn mould in your home. Proper prevention is key to maintaining a healthy living environment free from mould issues. Regular maintenance and attention to moisture levels will help ensure that stubborn mould doesn't become a recurring problem in your household. Taking these preventive measures seriously will save you time and effort in the long run.
