As I understand, the first step in kashering a kitchen is to thoroughly clean everything and then leave it untouched for 24 hours (eino ben yomo).
Would it be technically permissible to clean the appliances/surfaces/utensils after, not before, leaving them untouched 24 hours?
Practically speaking, it can be hard to kosher a kitchen while needing to eat from it; there are cases where this alternative could make it much easier. I'm not sure of every reason why it might be allowed, but I do know that any food potentially stuck to the appliances would probably be considered stale after 24 hours (or, in my case, the six months that the clean kitchen has been lying untouched). Stale food is of a different category in many kashrus situations.
So, can I clean everything again and then get right down to kashering? Or must the eino ben yomo strictly be after cleaning?
