We made a horrible discovery last night. A bunch of the shelves in the kitchen in our new place are covered in sticky goo. We got some of it off when we went over this evening, but ruined a sponge in the process (the stuff won't come off!). It really makes me wonder what the previous tenants were doing with the place. Well, that and the odd fridge smell and the empty pull-tab Arabic Pepsi abandoned on its side in one of the cabinets.
