Product Description

RenderKleen render cleaner and stain remover in 20-litre jerrycans is becoming more common as septic tank safe cleaning products in the maintenance and the building trade and it is a highly effective and safe product for cleaning rendered walls. It is a certified food-safe product so will cause no harm to us or our pets and the airborne spray and run-off is harmless to humans or aquatic life.

How Does The RenderKleen Algae Clean Work? It is different from most conventional cleaning chemicals in utilising nano-energy packages within the agent that penetrate deeply and lift off the algae and dirt leaving a clean surface that also lasts for longer than when treated with sodium hypochlorite (bleach) or a biocide-based soft wash render treatments.


You could think of these nano-energy packages as being like piranhas in the Amazon that are just milling around and waiting to attack and tear dirt away like piranhas would feed by tearing meat off the bones of their prey.

A safe, stable, non-hazardous and non-toxic k rend algae clean chemical with no biocides, acids, or bleach, we believe this render stain remover is one of the best-value render cleaner mixes out there and far more sustainable and preferable to cleaning render with bleach.
