Cool! Yes, they are reusable. Just rinse out after every batch. To pry off the tap, I just used a plain table/butter knife. It's easiest to clean the bladder if you remove it from the box - obviously the bladder has to be empty before you remove it. This avoids accidentally soaking the cardboard box and thus weakening it as you fill and empty with water repeatedly to cleanse it.
Once you it is clean, replace it back into the box and re-seat the cardboard "door" surrounding the bladder opening. Now fill carefully and replace the valve. You're good to go.
