The Process

1. Apply Mould Remover

2. Agitate

3. Dwell for 10 minutes

4. Rinse

5. Finish off right

Apply Solution – Firstly, we need to apply the solution, in this case RG Mould Remover, to the affected area. You will see the Mould Remover begin to fizz where there is mould. This is the hydrogen peroxide reacting with the organic mould matter. It is an excellent visual aid to indicate where mould is present, as mould isn’t always visible to the eye.
Agitation – Now agitate the affected area with the scrubbing brush. This will ensure the solution contacts and penetrates all of the mould mass. Although some areas are unable to be reached, where possible agitation will make a big difference.
Dwell – Leave the Mould Remover to dwell for at least 10 minutes. Dwell time is very important to ensure success. It will allow the solution to fully reach and eradicate the mould hyphae and spores.
Rinse – Wipe down the area with a clean cloth, until the cloth comes up clean. Do not use water to rinse any surfaces as extra moisture will promote new mould growth. The residual moisture of the Mould Remover is designed to be safe for substrates, humans and pets.
Finish off right – Finish off the job by lightly applying Mould Remover to the affected area and wiping away excess moisture. This ensures that what remains on the surface is fresh Mould Remover. This will guarantee a complete kill and retard future mould growth.
