Newborn poop

Ok so I’ve started using a couple AIOs and today I’m doing prefolds. Do you pre rinse the poo and get/keep the diaper wet? The AIOs are already dried out because it was during a time when he wasn’t peeing/pooping that much. But today with the prefolds it’s like soaked and there’s a lot more poo so I’m sure they’d stay wet in a bag. How do you get these clean or will they get clean in the washer with the multiple cycles? We don’t have sunshine so I can’t hang dry most of the days.
