DIY Mould Treatment

A mould and mildew treatment for bathroom surfaces and grout

Mould on grout and bathroom surfaces is one of the most common household problems, and most commercial mould sprays use chlorine bleach as the active ingredient. This formula uses Hydrogen Peroxide: a gentler oxidiser that works on contact without the fumes, the skin irritation or the damage to coloured grout. There are no Essential Oils in this formula and that is deliberate, because the peroxide degrades them and they would weaken the treatment rather than help it.

Yield 500 mL · Difficulty Beginner · Time 5 minutes

Ingredients

• 300 mL Hydrogen Peroxide 3%
• 200 mL Distilled Water

Method

1. Put on rubber gloves before mixing.
2. Add the Hydrogen Peroxide to a clean amber or opaque spray bottle.
3. Add the Distilled Water.
4. Swirl gently to combine; do not shake.
5. Label with product name, date made and all safety warnings.

Equipment

• Amber or opaque 500 mL spray bottle
• Measuring jug
• Rubber gloves

How to use

Ventilate the area well and wear gloves. Spray directly onto mould-affected surfaces. Leave for 10–15 minutes, up to 1 hour for severe mould. Scrub with a brush, then rinse or wipe clean. To stop the mould returning, follow up with the Mould Preventer (1.17).

Storage

Store in an amber or opaque bottle in a cool, dark place. Use within 3 months; Hydrogen Peroxide degrades over time.

Safety

Wear gloves throughout; Hydrogen Peroxide is a mild oxidiser. Store in an amber or opaque bottle, as light degrades Hydrogen Peroxide. Do not mix with vinegar. Ventilate the area well during use. Hydrogen Peroxide is a mild bleach and can lighten fabric; keep it off clothing, towels and coloured bath mats, and wear old clothes when treating mould. Keep out of reach of children and pets.

What else is in this recipe

• Distilled Water dilutes the Hydrogen Peroxide to the correct working concentration and leaves no mineral deposit on grout as it dries
