I use tide soap and warm water. Then rinse with warm water. During incubation I sometimes add a couple teaspoons of bleach. I also add a teaspoon or two just before they hatch. When I have done this chicks hatch like popcorn.
I know others that just use soap and water. What works for some may not for others.
This year I used soap and water once or twice that's it. Chicks everywhere!! Very low mortality rate too.
Has anyone ever used Young Living Oils Thieves cleaner on their incubator? Or Dawn dish soap? I am considering both, as Thieves is supposed to be antibacterial (clove, lemon, cinnamon, eucalyptus, and rosemary.)
