When the family is small the worry is always that the little ones will crawl around and pick up germs from all the muck an dust that infiltrates the home.  Those carpets, so lusciously soft and inviting, may look nice and clean after the daily vacuuming, but they still harbour and unimaginable number of foreign bodies.  Then there is the kitchen – how many times have we left Junior to crawl around on the floor – our best intentions to keep them entertained going straight out of the window as soon as cooking time arrives.  My own child used to be plonked in a ‘baby walker’ wheeled device, and off she went with a small box of clothes pegs to play with on the inbult tray.  Failing that, it was the floor getting the fast side legged crawl.

In all homes, the thorough cleaning is essential but in laboratory or hospital areas, only professional thorough cleaning will suffice.
