HG Mould Spray Review & Test Results – Does It Really Work?
HG Mould Spray works fast to tackle mould and mildew, wiping out those unpleasant black stains both indoors and outdoors. It’s ideal for bathroom tiles, grout, silicone seals, toilets, kitchens, basements, saunas, swimming pools, garages, and even garden ornaments or balcony surfaces (but it should not be used on wood).
One of the standout features is how effortlessly it restores surfaces. In bathrooms especially, it removes black mould spots with ease, leaving a clean finish without scrubbing.
Although the bottle looks simple, HG Mould Spray is one of the most effective mould removers on the market. Its cleaning power comes from a blend of sodium hypochlorite (a tried-and-tested bleaching agent) and sodium hydroxide (a strong cleaner that breaks down organic matter like grease and oils). Together, these ingredients don’t just kill mould—they also lift it away completely.
To add extra value, the formula includes a special additive designed to slow down mould re-growth. This is particularly useful in homes with damp or condensation problems, reducing the need for frequent re-treatments.

HG Mould Spray Usage Tips – How to Get the Best Results
To make the most out of HG Mould Spray and protect your home surfaces, follow these simple but important tips:
1. Always Ventilate the Area
HG Mould Spray gives off a strong chemical smell, similar to the chlorine scent you notice in swimming pools. If you’re applying it in larger amounts, the fumes can feel quite intense. Always open a window or switch on an extractor fan to keep the room well-ventilated and let the odour disperse quickly.
2. Wear Protective Gloves
Because the spray contains sodium hydroxide, which is caustic, it can sting your skin—especially if you have cuts or cracks. The smell can also cling to your hands. Wearing gloves not only protects your skin but also makes clean-up much easier.
3. Don’t Leave It on Longer Than Recommended
HG Mould Spray is powerful, so avoid leaving it on surfaces for longer than the manufacturer advises. If applied to paintwork for too long, you may notice slight discolouration. This usually fades back to normal over time, but it’s best to minimise the risk—particularly in areas that need regular mould treatment due to damp or condensation.
