Mould Remover

Beyond the visual problem and the musty odour, black mould has been linked to health issues, particularly for people with respiratory conditions. Removing it quickly, hygienically, and with the right product matters for both the appearance of your home and the health of the people living in it.

GK Mould and Mildew Cleaner is a professional-strength cleaner formulated to remove stubborn mould, mildew, grime and household contamination from hard, colour-fast surfaces. The formula penetrates mould spore roots so they decompose properly, leaving a bright, residue-free finish. Regular use helps to prevent mould from reappearing, giving you a cleaner, healthier home environment.

Why Black Mould Forms

Black mould develops where three conditions exist together: moisture, organic material to feed on, and limited airflow. In a typical home, that means:

• Bathrooms: warm, humid air from showers and baths condenses on cold surfaces and seals
• Kitchens: steam from cooking and washing up, especially in poorly ventilated areas
• Bedrooms with external walls: condensation forms on cold corners, behind wardrobes, and around window frames
• Utility rooms and basements: persistent low-level damp from washing machines, dryers and ground moisture

Mould isn't dirt and it isn't a stain in the conventional sense. It's a living organism with roots that embed into the surface, which is why ordinary household cleaners struggle to remove it permanently. A dedicated mould cleaner needs to penetrate those roots and break down the organism, not just bleach the visible surface.

Why GK Mould and Mildew Cleaner Works

GK Mould and Mildew Cleaner uses chemistry that penetrates and decomposes mould spore roots, rather than simply bleaching the surface. The formula is:

• Bleach and acid free: safer to use around the home, won't damage colour-fast surfaces, no risk of chlorine fumes
• Biodegradable: breaks down naturally and is water-rinsable
• Low odour: barely perceptible, suitable for indoor use without ventilation issues
• pH 8 (virtually neutral): gentler on surfaces than acidic or strongly alkaline cleaners
• 100% water soluble: rinses away cleanly without leaving residue

Coverage averages 15m² per litre, depending on the level of contamination. Heavy staining may require additional treatment.

Where to Use GK Mould and Mildew Cleaner

Suitable for use throughout the home on hard, colour-fast surfaces, including:

• Silicone seals around baths, basins, and shower trays
• Grout between tiles
• Shower cubicles and enclosures
• Ceramic and porcelain tiles
• Acrylic baths and shower trays
• Chrome and stainless steel fittings
• Single and double-glazed window frames

Not suitable for: mouldy wallpaper, soft furnishings, fabrics, or non-colour-fast surfaces. Always test on a small hidden area before full application.

How to Use

1. Prepare: Remove any loose dirt from the surface before application.
2. Test: Always conduct a small test on a hidden portion of the substrate before full application.
3. Spray: Apply a generous coat at a distance of 15-20cm from the affected area.
4. Allow to dry: Leave the product to dry completely.
5. Agitate: Once dry, work the affected area with a soft brush or pad to lift the residue.
6. Wipe and rinse: Wipe off mould/mildew residue with a damp cloth or kitchen towel, then rinse the area thoroughly with clean water.
7. Repeat if needed: For stubborn stains, reapply and repeat steps 1 to 6.

Keep children and pets away until the surface is completely dry. Shelf life is 24 months in the original unopened container.
