Cillit Bang vs HG Mould Spray: A Speed Test on Black Mould Removal
Black mould presents a persistent and unsightly challenge in many households, particularly in corners and ceilings of upper rooms. Beyond its visual displeasure, prolonged exposure to black mould can lead to serious health concerns, making effective removal a priority for homeowners.
The Search for a Quick Solution
While traditional methods like white vinegar can yield results, they often require hours of waiting. In pursuit of a faster remedy, I turned to mould-specific cleaning sprays available in stores. Cillit Bang and HG stand out as the most popular brands in this category, prompting a direct comparison to determine which performs better in real-world conditions.
Testing was conducted on two rooms in my home that consistently develop severe mould on the ceilings, despite regular ventilation efforts. For consistency, I used Cillit Bang Black Mould Spray in one room and HG Mould Spray in the other, ensuring windows were open during application due to the strong bleach content and potent odours of both products.
HG Mould Spray: Detailed Application and Results
Priced at £3.19 from Home Bargains, the HG Mould Spray features a nozzle that requires a 45-degree turn to activate. Following instructions, I sprayed the mouldy area from a distance of three to five centimetres. The product disperses as a fine mist, which can spread widely, necessitating the use of a face mask to avoid inhaling the substance.
One notable issue is the tendency for the solution to drip down surfaces after application, so keeping a cloth handy is advisable. Although the manufacturer recommends leaving it for 30 minutes before wiping, I monitored progress every few minutes. After just 10 minutes, the mould had lightened significantly, and wiping with a clean sponge and water caused it to vanish easily. A final wipe with a wet and dry cloth removed any bleach residue.
Cillit Bang Black Mould Spray: Application and Efficiency
At a slightly lower cost of £2.99, the Cillit Bang Black Mould Spray also requires turning the nozzle to an "on" position. However, its foam consistency differs from HG's mist, making direct spraying from the recommended 20cm distance impractical for ceiling mould. Instead, I found it more effective to apply the foam directly to a cloth and dab it onto the affected area.
Remarkably, within 20 seconds, the mould began to disappear, and wiping instantly removed it without scrubbing or extended waiting time. As with HG, I finished by cleaning the area with a wet and dry cloth to eliminate bleach residue.
Comparative Analysis and Recommendations
Both products proved effective at eliminating black mould, but key differences emerged in their performance. The HG Mould Spray, while successful, required a longer application time and posed issues with mist dispersion and dripping. In contrast, the Cillit Bang Black Mould Spray acted faster, was easier to use due to its foam texture, and came at a lower price point.
Overall, I recommend both sprays for mould removal, but Cillit Bang holds the upper hand in terms of speed, cost-effectiveness, and user convenience. This test highlights that while brand loyalty may vary, practical considerations like application ease and quick results can significantly influence the best choice for tackling household mould problems.
