Even though you might enjoy your conservatory sometimes it is neglected when it comes to cleaning the outside as there are usually hard to reach places, such as the roofs and walls. The Irish weather conditions can be damp and algae, moss and lichen can thrive in these conditions leaving your conservatories marked or discoloured. Softwash system is a better way of cleaning your conservatory. It kills algae, moss and lichen at the root and breaks the growth cycle for 3-5 years. Softwash is a safe bio-degradable chemical not harmful to plants,grass or pets, but kills the algae, moss and lichen at the root.
