The hygiene standards for cleaning the floors of kindergarten classrooms with hand-free mops

When cleaning the floors of kindergarten classrooms, the use of hand-free mops should follow the following hygiene standards to ensure environmental safety and hygiene compliance:

Disinfection treatment before:

Before daily cleaning, the mop head should be soaked and disinfected in 84 disinfectant solution containing 0.05% effective chlorine for 10 to 15 minutes to ensure no pathogenic bacteria remain.

Cleaning operation specifications:

Mopping sequence: Work in one direction from the innermost part of the classroom to the door to avoid secondary pollution.

Dry and wet control: The moisture content of the mop should be controlled at no more than 30%, with the standard being that no obvious water stains are left when walking on the ground.

Disinfection finish: After the cleaning is completed, mop the floor with clean water and then thoroughly absorb the remaining moisture with a dry mop.

Cleanliness of the mop head

After cleaning, there is no odor and the proportion of stains is no more than 3%.

New mops should be replaced every week. Damaged or deformed mops need to be replaced immediately.

Mop handle maintenance

The surface is free of dust and stains. The dust residue within every 10 centimeters in length is no more than 0.05 grams, and the stain area is no more than 0.5 square centimeters.

The connection of the mop rod needs to be inspected regularly to prevent loosening and falling off during the cleaning process.

Surface cleanliness:

There are no scraps of paper, no hair, no grains of rice or other debris. When checked against the light, there are no water marks left.

The corners, around the legs of tables and chairs and other hard-to-reach areas need to be cleaned with priority to ensure there is no dust accumulation.

Disinfection effect:

A thorough cleaning should be carried out at least three times a day (once in the morning, once at noon and once in the evening), and the floor should be wiped with disinfectant after each cleaning.

The floor should be deeply disinfected once a week. After wiping with chlorine-containing disinfectant, keep the contact time for 30 minutes.

Mopping usage norms:

It is strictly prohibited to "mop all the way through" without rinsing or washing. After each cleaning, the mop head must be thoroughly washed.

The mop head is designed to rotate 360 degrees to ensure that it can clean narrow areas such as under tables and chairs and in corners.

Child safety protection

During the cleaning process, a "Cleaning in Progress" warning sign should be set up to prevent children from slipping.

Cleaning supplies (such as disinfectant) should be stored out of the reach of children to prevent accidental ingestion or contact.

Storage requirements for mops:

After cleaning, the mop should be hung in a well-ventilated area with the cloth facing down to avoid water accumulation.

The mop bucket needs to be cleaned daily, and the filter screen should be disassembled and deeply cleaned weekly to prevent bacterial growth.

Training and Inspection

Cleaning staff need to receive regular hygiene knowledge training and master the correct usage methods of cleaning tools.

Kindergartens need to establish a hygiene inspection mechanism, conduct random checks on the classroom floors every day, record the cleaning conditions and rectify the problems.
