In this episode presenter Greg Foot investigates three products that promise to make washing your laundry better for the planet.

Listener Clare wants to know if the Ecoegg she’s using really is a greener alternative to liquid detergent and whether the cleaning pellets inside are harmful to the environment.

Another listener, Jane, got in touch about laundry sheets – strips of concentrated detergent that go inside the washing machine’s drum. Is the slightly higher cost worth it to cut down on waste?

And finally Mary wanted to know about filters that capture harmful microfibres which are shed from our clothes in the washing process and get into the environment, causing huge problems for marine life.
