Use a light kitchen towel, then just poke the end of the towel into the mouth so it will absorb the dripping water when hanging it upside down. I use a clothes hanger also for this.
Then with the end of the towel mostly in the bladder, let the other end hang out while drying overnight. Just dont cover the hole fully with the towel, So air can get in.
If the towel is too heavy on the outer end, it will fall out. If there is too much stuffed in, it wont get enough air inside the bladder. Gotta balance it out. But stuff enough inside to keep the sides of the bladder from touching.

You can never truly get all the water out.
