Actiwash Pro 5L
Actiwash Pro 5L is a highly effective, near pH-neutral professional-grade biocide designed to remove and control unsightly organic staining on exterior surfaces. Ideal for trade and contractor use, it is a 5x more concentrated formula than standard domestic versions, delivering powerful cleaning performance with long-lasting results.
Actiwash Pro targets and controls red, green, and dark biofilm staining, helping restore surfaces without the use of bleach or chlorine. Its advanced anti-microbial formulation slows down recontamination, keeping treated areas cleaner for longer.

How Actiwash Pro Works
Actiwash affects the proteins and cell membranes of microorganisms, causing the release of nitrogen and phosphorus from their cells. When applied using a spray or brush-and-leave method, natural weathering processes gradually remove the dead biofilm staining over time.
Self-Cleansing Timeframe (Apply & Leave Method)
Green algae: Typically clears within 1 week
Red algae: Usually disappears within 2–3 weeks
Established dark staining: May take several months
Gradual lightening of surface contamination should be visible within the first few weeks after treatment. Severely affected areas may require a second application, though this is not usually necessary. Agitation with a stiff brush is recommended for heavily contaminated surfaces.
