ACTIWASH DOMESTIC BIOCIDE 5L
Keep your outdoor surfaces cleaner for longer with Actiwash Domestic Biocide 5L — a highly effective, nearly pH-neutral treatment designed to remove and control algae, mould, fungi, and organic staining on a wide range of exterior surfaces.
This premium biocide concentrate works deep within organic growth to break down and disrupt the microorganisms that cause visible staining — including red and green algae — helping restore surfaces while preventing rapid regrowth.
-
Highly Effective Organic Stain Removal – Targets green algae, red algae, dark stains, mould, fungi, and biofilm.
-
Long-Lasting Protection – Anti-microbial action slows recontamination so surfaces stay cleaner for longer.
-
Bleach-Free & Chlorine-Free – Non-bleaching formula that won’t cause discolouration.
-
Biodegradable Formula – Breaks down naturally with reduced environmental impact.
-
Hard Water Resistant – Maintains effectiveness even in challenging water conditions.
-
Excellent Coverage – 5L concentrate dilutes to make up to 75L of working solution.
Actiwash contains a powerful active ingredient that targets microorganisms by disrupting their cell membranes and stopping growth at the source. Once applied, organic growth is killed and gradually weathered away naturally — often without the need for pressure washing or heavy scrubbing.
-
Green algae: visible improvement within approximately 1 week
-
Red algae: clears in 2–3 weeks
-
Dark or established stains: lighten gradually over several weeks to months
For heavily contaminated areas, light brushing during application can help speed up results.
