Pour the mixture into use pillow case. Make sure the pillow case is still strong and the paper mixture is heady. Tied the pillow case and set a side to let the access water flow out.
This may take a couple of hours. Just relex and let nature take charge. Once the size of the pillow case reduce to half, it time for you to transfer it to your washing machine.
Tuck the pillow case to the bottom of the washing machine evenly to balance spinning. You cant do this with side loader washing machine.
Spin as usual. Repeat spinning will remove more access water.
