There seem to be any number of people on Facebook who seem to want to mix chemicals and come up with some "MagiMax" mix or other. Weird that people can fail as window cleaners and then think they can become Cussons. 
Ironically its only these type people who actually move us foreward. If everyone just accepted what is , then we'd never.... you get the picture.
Wether this guy gets it off the ground is another matter but i strongly believe we will soon see an alternative to purifying water to achieve the same results. I think it was Dave Willis who (at least for me) first mentioned dishwasher tablets and how they leave clean glass.

Just as Chamois leather users would never get their head around squirting water from a carbon pole probably.
