An interestng article on this product:
http://www.independent.co.uk/news/s...ould-revolutionise-manufacturing-1885158.html

"It sounds too good to be true: a non-toxic spray invisible to the human eye that protects almost any surface against dirt and bacteria, whether it is hospital equipment and medical bandages or ancient stone monuments and expensive fabrics. But true it is. The spray is a form of "liquid glass" and is harmless to living things and the wider environment. It is being touted as one of the most important, environmentally-friendly products to emerge from the field of nanotechnology, which deals in objects at the molecular end of the size scale. ........."
 
Marvellous stuff! And the good thing is - as the article says - it's derived from quartz (silica), not some stuff that countries would go to war over. It'd be great to see an end to harmful chemicals being chucked by the millions of tons down loos and basins every day around the world. Bad news for their producers and window-washers, presumably, but everything evolves, and this seems to point to a very positive way in reducing massive chemical pollution.
