An important factor in how to clean your house is to
ensure the tools you are using are also clean. Trying to
clean a house using dirty cloths and sponges is counter-
productive, so making sure they are sterile is a great
place to start.

​

Simply pop the wet sponge or cloth in the microwave
for 30 seconds to remove any bacteria. Wait a minute or
two before pulling it out as it will be hot. If you don't
have a microwave, you can also put your cleaning cloths
in the washing machine and your sponges into your
dishwasher, although this will take longer. Try to clean
your sponges and cloths after each use to prevent the
build-up of unwanted bacteria on the surface.

Depending on how often you use them, you should
replace your cleaning sponges on a weekly basis just to
ensure there is no build-up of unwanted bacteria.
