Our company has full Health and Safety Certification as well as Method Statements and we are able to provide References if required.
Our biggest strength is a spot free clean every time. The water is hard which means it has a high mineral content and has a parts per million reading of 390ppm. After the water has been through our purification process (reverse osmosis), the water is 000ppm, which is why the windows dry off to a spot free finish.
Using purified water means the windows stay cleaner for longer and as there is no residues or chemical on the glass, so when there is a rainfall, there is nothing to activate in the glass.
