My washing machiene was really skanky and smelling. I use cloth nappies, it NEEDS to get clean - otherwise poo smell hangs around in there! I loved Ecover at first, have used it for 2 years, but have finally givven up on eco solutions to the stink (tried vinegar, borax, bicarb, several extra hot empty washes, etc etc).
Now have a big box of ariel. I know I am murdering little fishies in the atlantic who are now drinking it. I feel crap.
