Everyone has different ideas about cleanliness, and we most often determine the need for cleaning by eye. Most of the recommendations on how to keep your house in order are based more on the experience of past generations than on scientific evidence.

At the same time, we clean not only for the sake of beauty, but also in order to get rid of pathogenic microorganisms. And in different areas of an apartment or house, different microbes with different life cycles live , which is important to consider in order to maintain cleanliness.

Microbiologist Jason Tetro and tidying expert Becky Rapinchuk share how often you should clean and why.

Bed sheets

Microorganisms that accumulate on the bed, get on it with dust and are considered relatively harmless.

But sweat, saliva, and other secretions of the human body that remain on sheets and pillowcases are an excellent breeding ground in which bacteria, dust mites, and other living creatures multiply rapidly.

Therefore, bed linen must be changed once a week, in extreme cases – once every two weeks. It is better to wash sheets, duvet covers and pillowcases at a high temperature – from 60 ° C and above, unless otherwise indicated on the labels.

sinks

They need to be washed and disinfected every day. Even if they are clean in appearance, microorganisms, including pathogens, actively multiply in them. Moisture, leftover food, dirt that we wash off our hands after being outside or going to the toilet – all this creates excellent conditions for the reproduction of bacteria, including E. coli and salmonella.

So at least once a day, wash kitchen and bathroom sinks with a cleaning agent and treat with a suitable household disinfectant.

Carpets and floors

Vacuuming or brushing carpets should be done once a week, or more often if there are pets in the house. This will help keep dirt and dust under control and prevent them from spreading throughout the house.

Floors should be washed at least once every two weeks, and more often is better, especially in the kitchen, where crumbs, drops of fat and other fragments of food fall on the floor.

Plumbing in the bathroom

A bathroom is an ideal habitat for microorganisms. Moreover, they can spread even up to a distance of two meters from the toilet. So it needs to be washed and disinfected at least once a week, and the tub or shower at least once every two weeks.

Also, do not forget about the curtains: mold appears on them very quickly, so they need to be washed and treated with a disinfectant at least once a week.

Towels

Bath towels collect many microorganisms, including staphylococcus aureus, various fungi and E. coli. Therefore, experts recommend changing them daily.

Kitchen towels should be washed at least once a week. If you’ve worked with raw meat and then wiped your hands on a towel, you need to put it in the washing machine right away.

kitchen sponges

Experts advise boiling them on the stove every two days or keeping them in the microwave for two minutes. And at least twice a month to replace with new ones.

It is important to understand that washing or washing a sponge with water and soap does not help get rid of the microorganisms that accumulate in it. Therefore, sterilization or replacement is necessary.

Doorknobs

They should be wiped at least once a week, especially when it comes to the doors to the bathroom or kitchen – they accumulate the most dirt.
