Scientists in Australia, one of the sunniest places on the planet, have discovered a way to rid clothes of stubborn stains by exposing them to sunlight, potentially replacing doing the laundry.

Working in a laboratory, the researchers embedded minute flecks of silver and copper—invisible to the naked eye—within cotton fabric. When exposed to light, the tiny metal particles, or nanostructures, released bursts of energy that degraded any organic matter on the fabric in as little as six minutes, said Rajesh Ramanathan, a postdoctoral fellow at RMIT University, in Melbourne.
