Antifungal cleaning

In the UK, if you’re trying to reduce fungal exposure in your home environment — especially important for those with CPA or ABPA — there are several effective antifungal cleaning solutions you can use safely and routinely.

Here’s a list of recommended antifungal solutions available or commonly used in the UK:

🧴 1. White Vinegar (Acetic Acid)

• Effectiveness: Kills many types of mould, including Aspergillus.
• How to use: Use neat (undiluted) on tiles, windowsills, bathroom surfaces. Leave for 30–60 mins, then scrub and rinse.
• Pros: Natural, low-toxicity.

Caution: Not suitable on stone surfaces like marble or granite.

🧴 2. Hydrogen Peroxide (3–6%)

• Effectiveness: Antifungal and antibacterial.
• How to use: Spray on mould-affected areas. Leave 10–15 mins, scrub, then wipe clean.
• Availability: Sold in chemists and online (e.g., Amazon UK).
• Tip: Can bleach fabrics or surfaces — spot test first.

🧴 3. Borax (Sodium Borate)

• Effectiveness: Inhibits fungal regrowth.
• How to use: Mix 1 cup borax to 1 litre warm water. Apply with sponge or spray bottle.
• Availability: Harder to find in shops, available online.
• Caution: Keep away from children/pets; don’t ingest.

🧴 4. Specialist Mould Sprays (Commercial Products)
These are widely available in UK hardware stores (B&Q, Homebase, Screwfix) and supermarkets:

Brand	Key Ingredient	Notes
HG Mould Spray	Benzalkonium chloride	Strong, effective on black mould.
Astonish Mould & Mildew Blaster	Sodium hypochlorite	Bleach-based, powerful but with strong fumes.
Dettol Mould & Mildew Remover	Sodium hypochlorite	Good for bathroom tiles and grout.

💡 Note: While bleach can kill surface mould, it may not penetrate porous materials (like wood or plaster) deeply.

🧼 5. HEPA Filtered Vacuum + Antifungal Surface Wipes

• Use a vacuum with HEPA filtration to reduce airborne spores.
• Clean surfaces with fungal control wipes (some contain quaternary ammonium compounds***).

🔥 Do NOT Use:

• Air fresheners or “mould foggers” not approved for respiratory-safe use.
• DIY essential oil blends (like tea tree) unless confirmed safe — some oils can worsen respiratory irritation.

🛒 Where to Buy (UK):

• Boots: Hydrogen peroxide, Dettol products.
• Amazon UK: Borax, HG Mould Spray, vinegar in bulk.
• B&Q, Wickes, Screwfix: Specialist mould removers.

 

*** Here’s a deeper look at quaternary ammonium compounds (QACs) — often found in cleaning products marketed for killing mould, fungi, and bacteria — and their relevance for people with CPA or ABPA:

---

🧪 What Are Quaternary Ammonium Compounds (QACs)?

Quaternary ammonium compounds (often shortened to “quats”) are broad-spectrum disinfectants used in many household cleaners, hospital disinfectants, and antifungal sprays.

They’re especially effective against:

• Fungal spores (including Aspergillus on surfaces),

• Bacteria,

• Viruses (enveloped types like coronaviruses),

• And can inhibit regrowth of mould on treated surfaces.

🧼 Common QAC-Containing Products (UK)

🟡 Note: Always check the label — not all Dettol or Zoflora products contain QACs.

💡 Why QACs Matter in CPA and ABPA Homes

• CPA patients are at risk of colonisation or reinfection from Aspergillus spores, especially in damp, dusty, or unventilated environments.

• ABPA patients can react allergically to spores, triggering flare-ups of wheezing, coughing, or chest tightness.

• QACs are more effective than bleach at preventing fungal regrowth, especially on non-porous surfaces like plastic, glass, tiles, and sealed wood.

⚠️ Precautions When Using QACs

Although QACs are highly effective, they can be irritating to lungs and skin, particularly if:

• The area is not well ventilated,

• The product contains added fragrance (as with Zoflora),

• Used in aerosol sprays (fine mist can be inhaled).

Tips for safer use:

• Use gloves and open windows when cleaning.

• Avoid spraying into the air; apply with a cloth instead.

• Choose unscented, low-fragrance options (e.g., hospital-grade wipes or Dettol Surface Cleanser).

• Do not mix with other products like vinegar or bleach — can release dangerous fumes.

✅ Safe-for-Lungs Options (with QACs)

If you or a loved one has ABPA or CPA, consider:

• HG Mould Spray — effective and well-tolerated if room is ventilated.

• Clinell Universal Wipes — used in NHS settings, fragrance-free versions available.

• Dettol Surface Cleanser Spray (Clear bottle) — QAC-based, not bleach-based, less irritating.
