I everybody 
I have a new warm moisture humidifier (by Bionaire) and in the instruction leaflet, they reccomend to "disinfect the water tank by filling it with a solution of a half tsp of chlorine bleach in a half gallon of water".
What can I use to replace bleach that would be more "natural"?
Thank you!
