How dirty can a door handle be? Not very, you might think. But you'd be surprised. Handles on doors and living room furniture see a lot of action and can easily become bacteria hotspots, so wipe them down on a regular basis.

We all know floors are a bit downtrodden - they're always being walked over by everyone. Dirty shoes or pets who have been outdoors can bring bacteria and germs from the outside in, so it's vital that hard floors are not only cleaned, but also disinfected.

Shelves, sideboards and units can be neglected when it comes to cleaning, especially if you're just giving them a cursory run over with a feather duster. Wipe them down regularly to make sure they don't turn into unexpected breeding grounds for bacteria.

From food and drink spills, to cheeky people putting their feet up, coffee tables can see a lot of use. If not cleaned thoroughly, splashes, dirt and other residues can build up, causing bacteria to spread. So it's super important to clean and disinfect regularly.

Items that are handled regularly, such as remotes and games console controllers, can make perfect environments for bacteria to spread in, especially if people touch them with grubby mitts.
