HG Hagesan headstone cleaning spray
Weather influences cause mould, algae and moss growth on natural stones, plasterwork, masonry, etc. HG headstone cleaning spray is ideal for a thorough and effortless removal of all deposits, dirt, bird droppings and weather marks from marble, Belgian bluestone and other natural-stone gravestones; it is also suitable for plasterwork and walls. Spray HG grafsteenreiniger on the dirty marks from approx. 5cm distance, and leave to work for approx. 25 minutes. Any remaining dirt can be brushed off or wiped off with a cloth. Then rinse the surface with plenty of water. Repeat the treatment on persistent marks after 30 minutes. Half a litre is enough for a surface area of approximately 3m².
