I've used washable pads for Bitsy since day one and never a problem.
I use Pooch Pads and I bought really cute ones from Little Bit (here on YT) and I love em! I have 15 pads altogether and do a load once a week of just pee pads. I wash em with regular detergent with the bleach already in them. For the yuck factor, you could run an empty rince cycle with bleach after you wash the pads. I don't put my pads in the dryer, they dry pretty quickly on their own.
I have a large garbage pail with a lid, and I fold all the used ones in four (dirty side in), place them in a garbage bag in the pail until laundry time. No smell! Aside from the pee, they don't get too yucky. When Bitsy poops, I pick it up with toilet paper and flush the poop in the toilet. Her poop is really good, it doesn't smear or anything. I change out her pads everyday.
Kudos to you for going green! That's the whole reason I decided to do the washable pads in the first place. Washable pads are so great that I wish my cats would use them instead of kitty litter!
Good luck!
