I washed down one of my stained but not sealed plywood shelves yesterday and I can smell it still this morning. Worse, I can feel it. I was thinking about putting a coat of shellac on it last night, but because it was dripping wet and I was wearing a work shirt, I didn't. Now, of course, it would mean taking all the junk I just put on it off, taking it downstairs or outside and putting the shellac on it. I like shellac. It feels good going on. Water-based poly is OK, but there's nothing that feels good about it. OK, so maybe it is the alcohol fumes...
