I have a toaster oven that I use for dairy (to make grilled cheese for example). Recently my nanny used it to warm up chicken by accident. Is there any way to kasher the toaster oven at this point? Thank you.
If it was in it’s own pan/tray and the chicken itself did not touch any of the toaster, you should leave it unused for 24 hours, then put it on it’s highest setting for 15 minutes, then it can be used normally.
