PC keyboards
Crumbs, dust and flakes of skin collect here. So knock them out regularly and clean the spaces between them with cotton buds. Wipe the keys with a soft, lint-free cloth that is only slightly damp.
Rags
They are real germ spinners and should be washed every three days at a minimum of 60 degrees. Always hang up cloths after use so that they can dry quickly.
Toilet
The problem is not usually the seat or the toilet bowl. However, flushing does stir up a lot of bacteria which, according to a new study, can splash up to six meters away. So always flush with the lid closed.
Fittings
Microorganisms accumulate on them, just like on cupboard handles or frequently used appliances such as kettles. If they are not cleaned regularly, dangerous viruses can even survive on them for several weeks.
Kitchen sink
Although it is used frequently, it is often neglected when it comes to hygiene. Clean the surface of the sink thoroughly after each use with very hot water and washing-up liquid - otherwise a large number of bacteria will quickly settle here.
Contact lens container
The liquid in the container gives bacteria an ideal chance to survive, so that they can first settle on the lenses and later on the eyes. It is therefore important to wash out and change the container regularly.
Carpet
Lots of dust particles enter the house through airing, which easily settle in the carpet. But street dirt also accumulates - from shoes or pets. Vacuum regularly and use carpet cleaner once a month.
Raw food
This is where most pathogens enter the house, especially meat, fish and eggs. So put them in the fridge immediately - separately from other food - and use a separate board for cutting them.
Tupperware
With frequent use, the plastic becomes brittle and cracked, making it particularly easy for germs to penetrate. Wipe out thoroughly with water and washing-up liquid and leave to dry.
Cream jars
Up to 80 percent of all infectious diseases are transmitted via the hands. If you dip unwashed hands into a jar of cream, bacteria multiply particularly quickly. So only touch it with clean fingers or alternatively use a tube.
Fridge
Raw, sometimes unpackaged food piles up here. This makes it all the more important to clear out everything once a month and wipe out the fridge with vinegar cleaner.
