Persistent black mould and damp, particularly on external walls during the colder months, is a common and frustrating issue for many UK households. One individual has shared a highly effective, natural method that finally solved the problem, using a simple item found in most kitchen cupboards.
The Natural Powerhouse That Outperforms Bleach
Instead of reaching for a harsh, chemical-based mould remover, the reporter, Angela Patrone, decided to test a natural alternative: white vinegar. Commonly available with 5% acidity, white vinegar is a non-toxic cleaner whose mild acidic properties are proven to kill 82% of mould species. Crucially, it offers a significant advantage over traditional bleach. While bleach only removes surface mould and can sometimes worsen damp issues by driving moisture deeper, vinegar penetrates more effectively to tackle the root of the problem.
A Simple, Step-by-Step Guide to a Mould-Free Wall
The process is straightforward and requires minimal effort. First, ensure you use undiluted white vinegar for maximum potency. Angela used a standard cleaning-grade vinegar she had to hand. She generously sprayed the affected wall area, fully saturating the black mould spots, and then left the vinegar to work its magic for a full five minutes.
It is vital not to scrub or rinse during this waiting period, as the mould needs time to absorb the acidic solution. Remarkably, the mould began to disappear visibly without any physical effort during this time. After five minutes, she used a damp microfiber cloth to scrub away any remaining patches.
Ensuring Mould Stays Away for Good
For a lasting result, a final preventative step is key. After scrubbing and rinsing the area clean, Angela gave the wall one last light spray of vinegar and allowed it to air dry naturally. This helps eliminate any lingering spores and discourages rapid regrowth. While the pungent smell of vinegar can be off-putting, it dissipates quickly. Opening windows ensured the odour vanished within about 20 minutes.
To maintain a mould-free environment, Angela recommends a simple ongoing routine: cleaning the susceptible area with vinegar every fortnight. This proactive measure helps stop the mould from returning permanently, offering a cheap, effective, and eco-friendly solution to a perennial winter problem.
