Hydrogen Peroxide 3 % (Cobweb Mould Control)

Cobweb mould (Cladobotryum) can smother a fruiting block in 24 hours. A fine mist of 3 % hydrogen peroxide bursts its hyphae on contact, stopping the spread while leaving mushroom mycelium untouched. The solution then breaks down into water and oxygen—no residues, no extra rinsing.

Main Uses

• Treat outbreaks : Spray the fuzzy grey area and 2 cm beyond with undiluted 3 % H₂O₂. Repeat 12 hours later if growth reappears.
• Spot prevention : Lightly mist casing layers or tub walls after each harvest to discourage spores settling.
• Tool & surface sanitising : Wipe gloves, scalpels and mist bottles between tubs.
• Humidifier care : Add 5 mL per litre of reservoir water to keep biofilm down.

Why Hydrogen Peroxide?

• Rapid oxidiser—kills mould spores and hyphae within seconds.
• Leaves no chemical residue; safe for mushrooms when used as directed.
• Food‑grade 3 % solution supplied ready to use—no dilution maths.

Pack Size

1 L light‑blocking HDPE bottle.

Handling & Storage

1. Store sealed, upright and out of direct light.
2. Wear gloves and eye protection; 3 % can still sting skin and eyes.
3. Never mix with bleach or acids—dangerous gases may form.
