Its powerful anti-microbial formula slows recontamination, keeping surfaces cleaner for longer, while remaining safe for natural and synthetic materials. How It Works Actiwash targets proteins and cell membranes of microorganisms, releasing nitrogen and phosphorus from cells. A simple spray-and-leave or brush-and-leave method allows natural weathering to remove the dead biofilm. Actiwash Complete Treatment Guide 1. Resin Bound Stone Remove weeds and debris, then saturate the dry surface with diluted Actiwash. If moss is present, wait two weeks for it to turn orange before sweeping up, then apply a final saturation. The biofilm dies within 30 minutes, and natural weathering removes staining over time - green stains disappear within a week, red in 1-2 weeks, and black/dark staining over several months. Annual treatment is recommended.

Roof Remove moss before treatment and protect gutters. Saturate the dry roof with diluted Actiwash by spray or brush. For heavily contaminated roofs, brush agitation is recommended. The biofilm dies shortly after application, and natural weathering removes staining progressively, with green stains fading within a week and darker stains taking several months.

Lichens may be the last to weather away.

Timber Clean loose dirt, then saturate dry timber with Actiwash. Dense timbers require less solution per square meter. If white contamination persists after two weeks, lightly pressure wash and reapply. The biofilm dies within 30 minutes, and staining fades progressively through natural weathering. Re-treat at first signs of recontamination.

Cladding Remove loose dirt and identify staining types - note that orange iron staining requires a separate rust remover. Saturate dry cladding with Actiwash, allow to dwell briefly, agitate with a brush, then rinse with water. A final highly diluted spray-and-leave treatment can be applied to prevent streaking on suitable surfaces. Re-treat when contamination becomes noticeable.
