How to Use Delete Mould

Delete Mould is a powerful solution designed to treat mould, algae, moss and lichen on a wide range of indoor and outdoor surfaces.

Step 1 - Prepare the Area

Remove loose dirt, moss or debris before application. If using indoors, ensure the area is well ventilated by opening windows or turning on an exhaust fan.

Step 2 - Prepare the Product

The 750ml bottle is ready to use with no dilution required. For larger sizes, decant into a spray bottle or garden pressuriser for easier application.

A 20L drum will typically cover approximately 80sqm assuming the entire surface area is being treated.

Step 3 - Apply the Product

Spray directly onto the affected surface and allow the product to penetrate.

• Indoor surfaces (showers, grout, walls): Leave for minimum 20 minutes

• Outdoor surfaces (tiles, concrete, fences, roofs): Leave for minimum 60 minutes

For outdoor areas, lightly brooming the surface with a stiff broom after spraying can help improve penetration and speed up results.

Always do a small test spot first.

Step 4 - Rinse or Allow to Dry

Rinse gently with water or allow the surface to dry. For longer-lasting outdoor results, avoid aggressively pressure washing the entire surface clean, as leaving some of the active residue behind can help slow regrowth.

For heavy mould growth, lightly brush and repeat application if needed.

Scrubbing is usually not required unless the mould growth is very thick or there is excess debris.

Where You Can Use Delete Mould

Suitable for removing mould from many indoor and outdoor surfaces including:
Showers, grout, bathroom walls, internal painted surfaces, driveways, bricks, pavers, external walls, concrete areas, shade sails, roof tiles, sandstone, timber fences, walkways, pool surrounds, Colourbond surfaces, caravan awnings, tents and canvas materials.

Its specialised formula helps remove mould quickly while slowing future regrowth, in some cases helping prevent return for up to two years or more depending on conditions.

Important Tips

1. Vertical Surfaces
 - When applying to walls or roofs, avoid letting product run down untreated surfaces as this may leave marks. Apply from the bottom up or pre-wet areas below with water.
2. Plants & Grass 
- Delete Mould may affect plants and grass. Simply hose down surrounding plants before application to prevent absorption.
3. Ventilation - 
The formula has a strong odour as it contains bleach. Spray as a direct jet stream on the problem area rather than a mist and ensure good ventilation indoors.

Professional Strength Formula

Delete Mould uses a professional-grade formula containing sodium hypochlorite to penetrate porous surfaces and break down mould at the source. Main ingredients include:

• Sodium Hypochlorite (<10% w/w): The primary active ingredient that breaks down mould and deeply cleans porous surfaces. Commonly used in both commercial and household disinfectants.
• Sodium Hydroxide (<1.0% w/w): A pH adjuster that enhances the cleaning power of the solution.
• Disodium Tetraborate Decahydrate (<0.3% w/w): A stabiliser that maintains the formula’s effectiveness and shelf life.
• Surfactants (proprietary blend): Help the product spread evenly, penetrate surfaces, and lift away dirt, grime, and organic buildup.

It also delivers immediate whitening and brightening, acting as a 2-in-1 mould remover and stain remover.
