ACTIWASH PRO BIOCIDE 5L

Actiwash Pro is an effective biocide with a nearly neutral pH, ideal for eliminating and managing unsightly organic stains (red, green, and dark) on various exterior surfaces. This professional-grade formula is five times more concentrated than Actiwash Domestic, making it tailored for professional applications.

The active substance in Actiwash Pro Biocide, helps to remove algae mould and other single celled organisms from hard surfaces, by disruption of the cell membrane. Preventing photosynthesis and other physiological processes, leading to visible results in 12-24 hours.

Once dry Actiwash Biocide adsorbs onto hard surfaces creating a molecular film, which provides preventative action for a number of months. Green algae typically disappear within a week, red algae in 2-3 weeks. Well-established dark stains may take several months, but you will see a gradual lightening over time and should consider light brush agitation for heavily contaminated areas.
