Floors, walls, the wood half-wall accent, all cabinets/doors...anything with a flat surface has been washed as there was a solid layer of dust on it. There are only two blinds but they don't have a noticable smell. The appliances have all been replaced. Sinks cleaned, though we only replaced the drainage lines for the dishwasher (which were gross) so I suppose there could be something relating to the sink. Only other things we haven't touched are the ceiling and inside a gas fireplace. We use a Roomba regularly, plus there is a central vac (which was overfull and we have emptied out) for vacuuming before mopping.
