That's really sad!

I wish I could offer some suggestions, but I have always washed my cloth nappies (including BumG's) in my front loader on 60 degrees (the 2 hr cycle) plus I usually do a prewash if there is a lot of poo also. So far we've had no problems whatsoever, except my Baby Beehind are a bit crunchier than some friends who have top-loaders.
