Knockout Mould Spray from Barrettine is a highly-effective, powerful action spray that is designed to kill and remove mould spores, fungus and algae from grouting, silicone seals and other damp areas.

The spray has an anti-bacterial action, which helps to prevent re-growth and eliminates many fungal stains. It benefits from a 360-degree head for ease of use and provides accurate spray action for interior or exterior use. Supplied in boxes of six.

The Knockout brand is recognised for quality, says Barrettine, and boasts a comprehensive range of cleaners and unblockers at competitive prices.
