I also wanted to add that what really works for both the smell and stain (I mean, NO stains!!!) is Ecover's stain remover - like shout's pre-wash remover but natural. After I give the pads a quick handwash, I use the stain remover and rub it in with the bristle that comes on the bottle. I make sure that it stays on the wet pads for at last an hour or two before it's time for the laundry.
I just did a load that included a combination of glad rags (I'm not into these so much but..), Sweet Cheeks (I love these!) and these ones made by some woman in Oregon and they all came out smelling fresh and without a single stain.
