Removing and Preventing Ceiling Mould: We Test Three Cleaning Methods

Ceiling mould can be a stubborn issue that demands immediate attention to prevent spore multiplication and potential health risks. In this article, we share our experiences with three proven cleaning methods for eliminating mould from ceilings and offer valuable insights into preventing its resurgence.

Ceiling Mould: A Looming Danger

Ceiling mould not only detracts from the aesthetics of a space but also poses significant health risks, including allergies, respiratory problems, skin irritations, and asthma attacks, as reported by the NHS. Therefore, addressing mould promptly and effectively is of utmost importance.

In this guide, we delve into the top three cleaning products for mould removal from ceilings, scrutinise their advantages and disadvantages, and render a verdict on the most efficient approach.

1. Specialised Mould Spray

HG mould spray, available on Amazon for £6, is a highly recommended product for mould removal. This biocide is formulated to target and eradicate mould in various areas, including ceiling surfaces, bath or shower seals, and grout. HG also offers a foam spray variant suitable for hard-to-reach spots.

To utilise either product, simply apply it to the mould from a distance of 3-5 cm and allow it to sit for 30 minutes. Then, wipe off the mould with a damp sponge.

• • Pros: User-friendly and highly effective.
  • Cons: Toxic to aquatic life.
  • Verdict: HG mould spray impressively eliminated the mould with minimal effort. It does leave a faint chlorine odour, reminiscent of a pristine swimming pool, which may be a minor concern for some.

2. Household Bleach

For those who prefer not to purchase a specialised mould removal product, clear bleach (avoiding blue toilet bleach) can be an option. Ensure it contains chlorine as the active ingredient. Mix 250ml of bleach with water in a bucket, then apply the solution to the mouldy ceiling using a cloth or spray bottle. Leave it for 15 minutes, ensuring adequate room ventilation, and then wipe clean. Repeat as necessary until the mould disappears.

• • Pros: Cost-effective and readily available.
  • Cons: Toxic and may require multiple applications.
  • Verdict: While bleach exhibited some effectiveness, it demanded more time and effort compared to the specialised product. It managed to ameliorate the situation but did not completely eradicate the mould.

3. Soda or Vinegar

Another alternative involves using soda or vinegar. Dissolve 18 grams of soda in 3 litres of water and use a stiff brush to scrub the mould. Alternatively, mix a dash of vinegar with 1 litre of water and apply it using a cloth or spray bottle. Allow it to sit for 15 minutes before wiping it off.

• • Pros: Less toxic.
  • Cons: May require multiple attempts, and vigorous brushing could damage paintwork.

Final Verdict

The specialised mould removal product outperformed the DIY methods, offering a quicker and less labour-intensive solution, albeit at a higher cost. While bleach and soda exhibited some efficacy, they left visible mould marks upon close inspection.

Preventing Ceiling Mould

Preventing mould on ceilings entails addressing the root cause—moisture. Examine the area above your ceiling for potential leaks, particularly if the affected space is beneath a bathroom. Inspect plumbing, seals around bath and shower fixtures, and attic spaces for potential sources of moisture.

Inadequate ventilation can also contribute to mould growth. To counter this, ensure proper airflow in your home. Consider employing bathroom extractor fans and dehumidifiers to reduce moisture levels. Additionally, opt for ceiling paint designed for moist areas such as bathrooms or kitchens to deter mould growth.
