What is spring cleaning? What is cleaning.

Remember those days when there was a separate day for general cleaning in the apartment? Most often it was one of the days off - Saturday or Sunday. The whole family knew that on this day each family member had their own to-do list: mom cleaned the kitchen, dad washed the toilet and took out the trash, the children dust and sweep. But there were also things outside the list that were added periodically, for example: wiping the mezzanines from dust, washing doors or washing windows.

Remember your feelings on this day? The whole burden of the "obligation" fell on the shoulders: not having time to wake up, you immediately remembered what you "should" do and good mood evaporated. I wanted to get even more quickly and go to do more pleasant things. You knew that there was a bonus in the form of free time ahead of you and you would do what you want. Gritting your teeth, you took the hateful rags and did what you had to. What a pity this time!

On the other side. Spring cleaning days taught you a lot, such as patience, cleaning and keeping order, being careful about things, helping out and working together. You understand the main thing: your home requires regular maintenance, which takes a lot of time and effort. Knowing this, many of us use the services of housekeepers.

Once a week she comes to us and does a "general cleaning". In any case, we expect this from her and sacredly believe in it. Meanwhile, this is not entirely true! Try to make a list of what she does. In detail, for each room, point by point. You will be surprised when you realize that she never "gets her hands on some things". Then, this kind of work can hardly be called "spring cleaning", it is rather the maintenance of cleanliness. (Among the readers, of course, there will be those who will say that their housekeeper manages to do everything! We do not argue. Apartments are different in size, freshness of repair and overcrowding).

Hiring a housekeeper, we naively believe that now we do not have to do the cleaning and the house will always be perfect order... But why do we think that one housekeeper will handle all the affairs alone, when before the whole family was involved in this process for half a day?

In the classical understanding of most people, " spring-cleaning apartments / houses "- wiping dust from horizontal surfaces, vacuum and wet cleaning of the floor, ordering things, cleaning bathrooms, removing grease stains in the kitchen," removing obvious visible dirt "and plus / minus one action that takes a lot of time, for example: window cleaning, hood cleaning, cabinet washing inside. When carrying out "general cleaning", no one ever (and even more so the housekeeper) does not wash the lamps on the ceiling and cornices, does not dedust the walls, does not wash the doors, does not move the refrigerator, does not wash the ceilings, walls and pipes in the bathrooms, and also does not clean the heating radiators inside, etc.

To do a general cleaning of the house, which means to wash everything and everywhere alone, is an overwhelming task. No matter how much you have square meters, you will not be able to cope with the cleaning in one day, spend a lot of energy and nerves!
