A while back, a scientist in the UK created this new use of nano-particles that was applied to a glass surface. The particles, when exposed to sunlight, broke down any organic dirt material on its surface. So, when you wanted to clean the glass, all you had to do was wash it down with regular water. NO SOAP.
Turns out that a Japanese company has repurposed the concept with interior and exterior paint! Now you can just paint your house with this stuff and when it gets sunny, the paint breaks down the dirt and all you have to do is wait for it to rain!
