After we change a diaper we take it to the toilet, spray it and then toss it in a pail that lined with a whamie. We're not sure whether we need to put a solution in the pail, or if it's okay to just rinse and toss inside. The kissaluvs and prefolds are coming out stained, which I really don't mind, but if there's a way to help prevent it I'd love to know.
Our washing machine is a HE top loader if that makes a difference and it even has a diaper wash setting which I'm guessing is for a final rinse to get residue out. We only have 11 kissaluvs so we've been washing everyday so stink hasn't been an issue, but I wonder about bacteria growth with it sitting wet.
