I took the HOW CLEAN IS YOUR HOUSE Filthometer test at


http://www.channel4.com/life/microsi...quiz/index.jsp

and got rated clean but not pristine :P

Would you have told us, had you been rated disgustingly filthy?

I never clean the plughole. What does this mean and why do I have to
do maintenance on it?

You don't have to, but I find mine collects grease if I don't occasionally
treat it with caustic soda.
