I personally don’t reuse it because it grosses me out with all the yoke stuff that gets in it at hatching time. But I would be curious also.
I wouldn’t reuse it, because all the fluids that get on it during hatchling invite bacteria.
Agree w westridge. It’s not that expensive, it’s not worth the risk IMO.
You can reuse it. Rinse well, air dry, bake at 350 for 2 hours, store in a Ziplock.
