All good suggestions, thanx eveyone. Wouldn't have remembered to clean the drip tray. I just threw 4 boxes of baking soda in there for the night, I'll check it in the morning.
Not the sink, Vrai. I stuck my noise right down it, no odor. The kitchen itself is ok now, just took forever for the smell to disappear. And it's not even that it gets up your nose kind of thing. I'd go upstairs for the night, come back down and the smell would hit me, and it would only be the kitchen.
The fridge is getting the royal workover tomorrow. I fired the freezer up in the garage and will transfer stuff out there as I clean it. Most of the veggies and porous boxes are history. Everything else gets wiped down with Clorox or tossed.
I have never had anything stank up a fridge like that before, and I've had some pretty stanky science projects in there. Smell always goes away after a few days.
Worst case, I hate this fridge anyway. I'll go buy a new one.
