Best Product for Cleaning Tennis Courts

Best Product for Cleaning Tennis Courts
After extensive trials by Grimshaw Maintenance Division we recommend Qualgex as the best product to clean hard surface tennis courts. Qualgex is a moss and algae biocide which is suitable for most hard surfaces including macadam and grit tennis courts.  Whilst large clumps of moss may require a second treatment in order to get the product down to kill the lowest levels of the moss, most smaller moss and algal outbreaks can be hit with one application.  It also helps prevent regrowth of moss and algae within the court. 
5L of Qualgex will treat 500m2, so is usually just enough to treat a domestic court for algae and some moss. It will work on damp (but best not to be saturated, ie immediately after rain) moss. The moss needs to be actively growing, so we don’t apply it unless the temperature for the day is going to stay above 6°C. Make sure your equipment is thoroughly rinsed out from any weed killer or it reacts with any glyphosate based weed killer and forms a “goo” that blocks up the sprayer!
Qualgex is one of the strongest products on the market and is fully registered with the Health & Safety Executive.  All chemicals should only be used in full compliance with their safety instructions and recommendations as provided.
