At RoofBoss we use AlgoClear Pro cleaning chemicals.
AlgoClear Pro is a high purity quaternary ammonium. It is a biocide working by contact with microbial life. It will act on small organisms by puncturing their cell walls. Its concentration is 40%. High Purity means the product does not contain solvents and will not affect silicone additives / sealants / coatings found in modern construction products. AlgoClear Pro is recommended by K Rend. AlgoClear Pro is surfactant: It is a powerful soap. The product foam on impact at low concentration. It will, when brushed and rinsed, remove grime from a surface as well as sanitising it.
Algoclear Pro does not contain aggressive or oxidising agents such as bleach, acid, lye etc. and is neither corrosive, nor bleaching.
