An entirely environmentally friendly and innovative exterior building cleaner chemical that was part of a range designed for removing marine algae in harbour quaysides amid serious concerns around chemical discharges of substances like sodium hypochlorite into water courses.

Exterior building cleaner

How Does It Work?

BuildKleen is quite different from conventional building cleaning chemicals and our exterior building cleaner utilises nano-energy packages within the mix that penetrate deeply and lift off the algae, render staining and dirt leaving a clean surface that also lasts for longer.

BuildKleen cleans off the algae and green growth by breaking surface tension and without killing it and yet a surface treated with it stays algae-free for longer and in our tests, natural stone absorbs rain water in a more natural way that is almost like ‘breathing’.

Truly Eco Friendly

This environmentally friendly patio cleaner product dislodges and removes algae rather than killing the algae:

  • Contains no biocides, sodium hypochlorite or bleach.
  • Contains no strong acids or alkalis
  • Non hazardous and non toxic – certified food-safe!

These nano-energy packages could be thought of as being like piranhas in the River Amazon that are milling around and waiting to attack and tear dirt away like piranhas would feed by tearing meat off the bones of their prey. It is popular with many eco-friendly cleaning contractors in the exterior cleaning London market.
