If you have BBC America network, I really recommend that you watch How Clean Is Your House.
That's especially true if you've ever asked yourself that particular question.
The show can answer a lot of questions about your cleaning needs.
The show's stars are Kim Woodburn and Aggie MacKenzie, who are Britain's top cleaning experts.
The women go to some of the messiest homes in Britain, and occasionally in the USA, and not only clean them, but also give the homeowners valuable information and cleaning tips.
Kim handles a lot of great household tips.
For example, she's fond of teaching people the uses for lemon, salt, banana peels and more.
The tips save both time and money.
Aggie, meanwhile, is more of a grime detective.
She's often taking swabs of people's beds, carpets and refrigerators and sending them off to the lab to see what sort of dirt, bacteria or bugs the people might be dealing with.
Her goal is to shock people into action by showing them the bacteria and mold that are contaminating their homes.
At the end of the show, the home owners are sent away, finishing cleaning touches are handled and they're brought back for a big reveal.
Often, the show will also show clips from a few weeks later to show whether the family turned over a new cleaning leaf or went back to their old ways.
The thing I like about How Clean Is Your House is that it actually teaches the family and the viewers great tips for easier, faster cleaning.
I've learned a lot from the show that has actually saved me time and money in my own life.
