It seems if the kitchen and bathrooms are clean and the laundry and grocery shopping is done, and the sewing room cleaned up, I don't care about the dust. When I can see the dust on things on the high shelves that is when I say OK, that is enough , time to stop for awhile and get this museum cleaned up. I am kind of a hoarder but a neat one. I have a lot of stuff but it all has it's place. I always cleaned my kitchen cupboards one a year but now it has been 2 yrs. I seem to clean the small pantry about every two months and that is because I need to find stuff to cook with.
