By Andrew Moffat FROM Foyers Inverness

The biowash is fantastic, im going to be using it for all my roof cleaning jobs, works like magic, used it on a natural slate roof, left it for an hour or so then rinsed off, and it came up like new.

Product Description

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. 

  • Expected coverage: 250 mē per 25 Litre when diluted 1:1
  • 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.

Helps facilitate the easy removal from roofs of

  • Black and White Spot
  • Algae and Lichens
  • Moss
  • Surface Grime

Wear appropriate safety wear at all times. See technical page for more information.

It is important to ensure surface remains damp during 60 minute period as product becomes inactive once dry. Most ingrained organic matter and grime will be removed after one application.
