Cleaning the house is a long and tiresome chore. Most people clean the entire house once or twice a year. It's not called spring cleaning for nothing. Well that is just a figure of speech though. What I meant was that most people don't really look into cleaning as much as they should. People clean only out of necessity. Most of the time people even neglect cleaning some of the important areas around the house, sometimes they don't see reason, sometimes they are just lazy.
