I've been using Ecover liquid for a while, mainly for reusable nappies, but getting a bit fed up with its inability to remove stains in them and in the main wash. I also suspect that our drains get clogged up with the stuff quite a bit, possibly due to living in a hard water area. Are there any other better green options out there? I am open to persuasion re: EcoBalls, but I don't know anyone else who uses them... convince me!
