Dishwasher...??? Hmmm...I hadn't thought of that although I don't have one so it won't do me any good LOL
I used bleach water on my styrofoam bator. It left a strong odor too even after I rinsed well and dried in the sun. Somone suggested using peroxide instead of bleach water so the smell isn't so bad. Also someone told me to wipe down my bleach cleaned bator with vinigar to help reduce the strong bleachy odor.
I didn't know you could put them in the dishwasher but it is a great solution for sanitizing. Guess my mother-in-law will have to remove the stuff she stores in hers when my incubators need cleaning.
I clean mine with Peroxide and hot hot water. I dont like using bleach as it is very "fumey". I do use bleach on the plastic insert, just not the styrafoam.
