BioWash Surface Cleaner for Roofs is specifically designed for the BioWash Cleaning System

BioWash Surface Cleaner is a fast acting, high performance cleaning product that will enable a roof to be cleaned without intense pressure washing. BioWash Surface Cleaner will quickly remove all forms of organic growth from any type of roof tile including clays, without risk of damaging the roof. 

For best results on roofs dilute the product 1:1 and apply via your BioWash machine

For best results on render, such as K Rend, dilute the product up to 1:5 apply via your BioWash machine

Keep the roof tiles damp throughout the 60 minute period, then hose or lightly pressure wash away with clean water. For areas of heavy contamination or soiling, leave product on surface for longer or re-apply.

BioWash Surface Cleaner combines 4 powerful, active cleaning ingredients and a biocide to inhibit further growth of moss and algae.

Helps facilitate the easy removal from roofs of

  • Black and White Spot
  • Algae and Lichens
