A writer from Glasgow Live conducted a hands-on test of three popular mould removal products to determine which one effectively cleans grout in bathrooms. The test aimed to address the common problem of mould creeping into tile grout, which can make even a clean bathroom appear dirty, especially in areas with high moisture and poor ventilation.
Testing Methodology
Millie Bull, the writer, tested Astonish Mould Blast Stain Remover, HG Mould Spray, and Mould Magic on separate sections of grout to ensure a fair comparison. Before application, she dried the surface and wore gloves to prevent skin irritation. Each product was applied according to its instructions. Natural remedies like white vinegar and bicarbonate of soda were not included in this test, as they often fail to tackle stubborn mould effectively.
Product Performance
Mould Magic, priced at £12.99 for two tubes, is a thick gel that spreads easily and has a mild smell. It requires two to three hours to work fully, which demands patience. HG Mould Spray, costing between £4.29 and £6.50, has a foamy texture that initially clings to grout before gradually running. It takes 30 minutes to take effect but has a strong bleach-like smell, necessitating good ventilation. Astonish Mould Spray, the cheapest option at around £2, has a thin, watery formula that runs down tiles quickly and needs only 10 minutes to work.
Results and Observations
Astonish delivered impressive results despite its low price and lightweight formula. With a simple wipe, the mould disappeared, leaving the grout clean and stain-free, though it did not noticeably brighten the grout. HG Mould Spray also performed well; before wiping, the mould had visibly broken down, and after removal, the grout looked noticeably whiter. A quick rinse removed all residue. Mould Magic removed mould thoroughly with minimal smell, but it was harder to clean off, sometimes leaving a gel-like residue that required extra effort to remove.
Verdict and Recommendations
All three products proved effective, but HG Mould Spray came out on top overall. It struck the best balance between ease of use, cleaning power, and finish, leaving grout looking clean and brighter after just 30 minutes. While not the cheapest option, it delivered the most polished result. Astonish is a strong budget-friendly alternative, ideal for quick fixes, while Mould Magic remains a reliable choice for tougher jobs like sealant, despite requiring more time and effort. According to Millie, the right choice may depend on how quickly you need results and how much effort you are willing to put in.
