How to clean moss, algae & lichen on Roofs & Hard Surfaces
While there are multiple products for cleaning hard surfaces, the most effective and safest product is AlgoClear Pro and the AlgoClear line of products. AlgoClear products are simply sprayed onto the surface and left to work in most cases.
These products are commonly referred to as biocides and are a gentle but effective way of solving the moss and algae problem. The use of biocides to cleaning moss from roofs, driveways and other hard surfaces is called soft washing. Prior to the development of soft washing moss and algae removal was done via a pressure washer which can cause significant damage to the surface being cleaned. Render and mortar were also blasted away and surfaces were left saturated with water, which under freezing temperatures caused renders and bricks to crack and become brittle. The use of AlgoClear Pro moss and algae cleaner removes this risk completely. Occasionally bleach based Hypochlorite products are used, again these can cause significant damage, bleaching colour and corroding surfaces. AlgoClear Pro only reacts with biological substances and so will not damage or discolour any material, sealant, coating or fixing. AlgoClear Pro is a water based solution and contains no solvent or bleaching chemicals meaning it will not discolour any surface or damage leadwork, aluminium or fixing materials. Unlike bleach based products that must be rinsed from the surface AlgoClear Pro is simply sprayed onto the surface and left, this makes for a much more time and cost effective treatment.
AlgoClear Pro contains the active ingredient DDAC. We also market two alternative biocides in the shape of Mac Hi-Power and Ranger. We offer these product in unique pack sizes with Mac Hi-Power available in pack sizes ranging from 1lt up to 200lt which offers great value to the professional user. Ranger is from the ICL stable and offers a great option with it’s exceptional area of coverage.
IMPORTANT LEGISLATION CHANGE
Since the reclassification of Moss as a plant, products for the treatment of Moss now come under The Plant Protection Products (Sustainable Use) Regulations 2012. This means that only products that have HSE accreditation can legally be used for the control of Moss. To avoid breaking the law, contractors and private users must ensure that the product being used is appropriately approved.
DDAC (found in AlgoClear and AlgoClear Pro) carries this accreditation but many others do not. BAC Found in BAC50 and Ultima Plus XP) DOES NOT carry this HSE accreditation. Any previous recommendations for these products should now be considered invalid.
