Oh, I didn't answer the question when I posted before about the lemon juice.
I would say the dirtiest place in my house by far is the attic. It's gross up there. We had some squatters up there too for a while... I say squatters, because I do not remember ever signing a lease for critters to live up there, and they certinaly didn't pay rent. They left though, now that the orange tree is done. And when we get a new roof next month, they won't be able to come back in. HA!
If we're talking in the living areas of the house, I would say floors. The carpeted floors really, which are both bedrooms and the pink bathroom off the master bedroom. I just hate the vacuum cleaner as much as the cats do!!

Kitchen floor is made of an old linoleum pattern which hides dirt very, very well. So I don't do that often either. So if I drop anything, I don't even go by the 5 second rule.

The hardwood floors I sweep and Bona regularly though. At least I'm good with about half the floors!!
