These soluble strip laundry sacks are a great solution for collecting & washing laundry with minimal contact.The sack is loaded, still sealed, into the washing machine. At the end of the washing cycle, simply remove the disinfected polythene from the washing. The water soluble strip washes away and is of no harm to the environment. The polythene that is left may then be recycled. Items being washed should be laundered with the temperature and cycle as normally selected.
