I have a pretty strict cleaning schedule I stick to keep my anxiety down and everything under control. (I find I cannot study if my house has anything out of place.) I used to feel ok dusting my wood furniture once a week, but find its not enough and have been finding myself dusting twice a week otherwise you can see dust on the furniture.
A friend of mine and I were talking and she said she dusts once a month! She has a spotless house! I about fell over.
I think some of it is I live on the second story of an apartment on a main road (meaning more dust flying).
So I am curious...how often do you dust and what type of home situation are you in?
