As Britain faces an intense cold snap with temperatures plunging to -11°C, homeowners are battling not just the chill but also the seasonal surge of household mould. While many are seeking affordable ways to stay warm without astronomical heating bills, a simple 65p solution from the kitchen cupboard could help combat moisture problems.
The 65p Mould Solution Already in Your Kitchen
According to DIY expert Glen Peskett, ordinary table salt serves as an effective, natural dehumidifier that can significantly reduce condensation. This common household item works by pulling moisture from the air, making it particularly useful during winter months when mould tends to flourish.
Peskett recommends placing small bowls of salt on windowsills overnight, behind curtains, or inside wardrobes and cupboards - essentially any enclosed spaces prone to dampness. The reason for its effectiveness lies in salt's hygroscopic properties, meaning it naturally absorbs moisture from its immediate environment.
Why Salt Alone Isn't a Complete Solution
While this inexpensive hack can help manage light condensation, property experts caution that it's not a cure-all for serious mould issues. Verona Frankish, CEO of estate agency Yopa, explains that persistent mould usually indicates excess moisture combined with poor ventilation.
Frankish emphasises that unless homeowners address airflow and humidity at their source, salt alone won't resolve underlying problems, particularly in older or poorly insulated properties. She describes salt as a cheap supporting measure rather than a replacement for proper moisture control.
Long-Term Strategies for Mould Prevention
Property expert Phil Spencer highlights that mould isn't just unsightly - it can potentially jeopardise house sales and, in severe cases, devalue properties by up to 50%. A 2024 Checkatrade study estimated the cost of removing mould from an entire house could reach £1,200.
For lasting protection against mould, experts recommend several key strategies:
- Improve ventilation throughout your home, especially during showering or cooking
- Use extractor fans and maintain them properly to ensure they're not blocked
- Open windows before turning on hot water for showers or baths
- Dry condensation-covered surfaces daily with a cloth or towel
- Keep your house warm by turning heating on periodically
- Consider using moisture-resistant or anti-mould paint in high-humidity areas like bathrooms
- If drying clothes indoors, open windows or use a dehumidifier
While salt and disposable dehumidifiers can provide temporary relief, these more permanent solutions offer better long-term protection against winter dampness and the mould that follows.
