Have you ever been in a situation to feel a bad odour in your house and not to know where it comes from? What would you do if you happen to be in such situation? Would you search for the source of the smell on your own or call professional cleaners? What is the first place where you'd look for the source?

There are only a few places in every house, where a source of an odour can be hidden: in or behind the fridge; in or behind the stove; in some cupboard; under the sofa or between its cushions; and under the carpet. If I had a bad odour in my house the first place where I'd look would be beneath the carpet. This is the easiest thing to do and the chances to have anything bad under it are quite big, especially if you have pets or kids.

An expert from carpet cleaning London once told me that one can find really amazing and disgusting things under a rug. He shared with me only a few not so awful things that he's found. Here they are:

A big mess is a common picture after parties. Slices of pizza are something that fits pretty well under a carpet and people love to trick their friends. When the slice goes bad it starts smelling disgusting and if you don't look under your flooring you won't understand where does the odour come from.

Pieces of dog food – dogs love to store food. They normally bury it, but when there is no yard where to do it, they start hiding pieces of food under the carpet. Some dog foods are quite greasy and can leave stains. Not to mention the smell when they rot.

Our kids also leave us unpleasant surprises under the carpet. They usually hide things which they don't like eating, such as peanut butter sandwich. Peanut butter is greasy and sticky and can cause us a lot of troubles.

It may sound weird but sometimes carpet cleaning is not enough. You don't have to clean only over your flooring but under it, too.
