When i washed by hand, i rinsed and rinsed and rinsed in the sink. Then i soaked them in soapy water, ringing that through several times. then i boiled each diaper on the stove, then dropped in cold water (so i could touch) rinsed again and ringed dry.
i did this at least once a week till i could get to the laundry mat on sunday for 3 months.
since it will only be a week, could you seperate the poopy from just wet diapes?
and, i used rubber gloves.
