Cleaning exterior pathways and driveways with boiling water is another inexpensive way of removing moss and lichen. You do not need to hire a domestic cleaning Soho company to do that for you. The boiling water very quickly deforms the plant cells and kills the plants rapidly. Applying boiling water is not quite so easy, as the heating process of the water has to be done by the electric jug in the kitchen – unless you are lucky enough to have another way of heating the water to boiling temperature.
