I started off with using Purity. Then I switched to Earth Choice wool wash. I figure wool wash is more gentle than normal detergent. I've had no problem with it and I only use a small amount. It's cost effective and it doesn't pollute our world.

p.s. - I dry pail and I find that my MCN have a "odour" too. Is there anything you can use???
