Cleaning Incubator...

I used bleach and a scrub brush on my last hatch since only 3 hatched. poured bleach in the bottom, let set for a few min and scrubbed it out rinsed well and set in sun to dry,    marrie

I would use vinegar, it will clean, and give it a good smell, then if possible let it dry in the sun.  I avoid bleach whenever possible.

Went and looked this up for you.

This is from STOREY'S GUIDE TO RAISING CHICKENS by Gail Damerow:

Vacuum up loose down, sponge out hatching debris, and scrub the incubator with detergent and hot water.  When the incubator looks thoroughly clean, apply a disinfectant such as Germex or chlorine bleach (1/4 Clorox per gallon of hot water, or 30ml/l).  If possible, dry the incubator in the sun.

(Because hatching itself is a major source of contamination, clean your incubator after each hatch.  This will improve hatching success and also helps break the natural disease cycle in a flock.)

Hope that helps!

The cleaning instructions on my Genesis 1588 (styrofoam) says to vacuum the top where the heater & fan are and to use baby wipes for the top; I have a spray can of compressed air (office supply store) to blow out fuzz & dust and then I wipe down the outside of the thermostat, fan, and glass with "Wet-Ones" wipes. I spray out the bottom of the incubator, along with the wire floor and plastic water tray outside with the hose, then I bring them back inside and wash them in the bathtub with hot water & dish detergent, rinse, and wipe down with the wipes. Then they go back outside to dry in the sun.
Best of luck with your new (to you!) incubator!

I use diluted bleach in water, then I set out in the sun.

I saw a thread a few months ago where someone put the bottom of their bator in the dishwasher.

I think that would work well!
