Keeping gutters and pvc downpipes looking presentable is challenging in our damp British climate with ideal conditions for algae, moss, and lichens to grow and thrive. This calls for a gutter cleaning chemical that cleans in an environmentally friendly way without too much hard work and reduces re-infestation.

BuildKleen is just such a ready-to-use aqueous cleaning solution with industry-leading safety and effective cleaning performance for facilities managers and maintenance companies.

Gutter Cleaning Chemical

How Does It Work?

The process of cleaning gutters and uPVC fascia is by getting underneath the algae and dirt and loosening and dislodging it for rinsing off instead of killing the algae as is the case with biocide-based cleaners. Most brands of outside cleaning chemicals and fascia cleaning products use biocides – disinfectants – to kill the green growth whereas ours uses none.

In some cases, the biocide-based chemicals are biodegradable but toxic to aquatic life and in some cases to pets and carry hazard warning pictograms about how they can damage your skin. If you are concerned about the environmental impact of your activities, you’ll think twice before you use them on your gutters.

Gutter Cleaning Chemical

BuildKleen cleaner is stable, effective, safe, and environmentally friendly and biodegradable and is supplied in 5 litre or 20 litre jerrycans at ready-to-use dilution. Use of a power washer or garden hose is normally helpful in the cleaning process and disperses the dirt better after cleaning.
