Maintaining perfect cleanliness in the catering department of a preschool institution is not just a matter of aesthetics, but a strict legal requirement, violation of which can lead to outbreaks of intestinal infections among children. Refrigeration equipment is a high-risk area here, since it is where products that are not subjected to further heat treatment before serving, such as dairy products, fruits and ready-made meals, are stored. Therefore, the question of how to wash refrigerators in a kindergarten according to SanPiN is especially acute for managers and cooks, requiring a clear algorithm of actions and the use of exclusively certified compounds.
Regular treatment of internal chambers and external surfaces helps prevent the proliferation of pathogenic microflora, mold and unpleasant odors, which can easily transfer to food products. Unlike household use, where housewives often rely on soda or vinegar, in organized children's groups it is allowed to use only those products that have state registration and an appropriate safety certificate. Ignoring the rules for carrying out disinfection or using inappropriate chemicals can cause serious problems with Rospotrebnadzor and a threat to the health of pupils.
In this article we will analyze in detail the regulatory framework, the list of approved drugs, a step-by-step algorithm for carrying out general and daily cleaning, as well as requirements for equipment and documentation. Understanding these nuances will allow catering department employees to confidently carry out their duties, ensuring the safety and quality of food for children.
The regulatory framework and requirements for the cleanliness of the catering department
The main document regulating the sanitary and epidemiological requirements for organizations of education and training, recreation and health improvement of children and youth are current SanPiN 2.4/1.1.3686-21. This regulation replaced many old rules and combined requirements for educational and nutritional conditions. According to these standards, all premises of the catering unit, including refrigeration chambers and cabinets, must be kept in exemplary cleanliness.
Compliance with these standards is monitored by Rospotrebnadzor, which carries out scheduled and unscheduled inspections. During the inspection, attention is paid not only to the presence of dirt, but also to the correctness of the cleaning work, the presence of marked equipment and log books. Lack of evidence of regular disinfection equates to a violation of sanitary rules with all the ensuing consequences.
Particular attention in regulatory documents is paid to the separation of flows of raw and finished products, which directly affects the schedule and methods of washing refrigerators. Chambers for storing raw meat, fish and eggs must be processed with greater care and frequency than cabinets for ready-made food to prevent cross-contamination.
Approved detergents and disinfectants
The choice of chemistry for processing equipment in a kindergarten is limited to a strict list of drugs approved for use in food production and social institutions. The main selection criterion is the availability of a certificate of state registration (SGR) and instructions for use, which clearly state the concentrations of working solutions.
The most common products used in preschool institutions are products based on chlorine, quaternary ammonium compounds (QACs) and oxygen-containing preparations. Chlorine-containing compounds, such as “Diseffect” or “Whiteness” (in certain concentrations), are effective against most bacteria, but require careful rinsing due to the specific odor and possible irritation. Preparations based HR, for example, "Alaminol" or "Septodor", have a good cleaning effect and are less aggressive to metal surfaces.
⚠️ Attention: It is strictly forbidden to use household cleaning powders with abrasive particles that can scratch the interior coating of the refrigerator, creating ideal conditions for the growth of bacteria in microcracks.
For daily treatment, less concentrated solutions are often used, while more powerful disinfectants are used for general cleaning and mold control.
Graph and frequency of cleaning
The cleanliness of refrigeration equipment in the kindergarten is maintained through strict adherence to the cleaning schedule, which is divided into daily and general activities. Daily cleaning is carried out at the end of each shift or before loading a new batch of products and includes removing visible dirt and wiping the shelves with a damp rag with a cleaning solution.
General cleaning of refrigeration chambers and cabinets is carried out at least once a week, and more often during intensive use or in the summer. During this procedure, the equipment is cleared of food, defrosted (if there is no No Frost system, which requires a special approach), washed inside and out, disinfected and thoroughly ventilated before switching on.
Food department employees are required to keep a log of general cleaning, which records the date, the product used, the concentration of the solution and the name of the person in charge. This document is the first one requested by the inspection authorities during an inspection.

Step-by-step instructions: how to properly wash a refrigerator
The process of washing refrigeration equipment in a kindergarten should take place in a certain sequence to ensure maximum efficiency and safety. First, you must completely empty the chamber of products, transferring them to backup refrigeration equipment or heat-resistant containers with ice, if there is no spare space.
Next, you should disconnect the unit from the power supply for the safety of personnel and defrost it if ice has formed. After removing the ice and water, the main stage begins: preparing a working solution of the disinfectant strictly according to the manufacturer’s instructions. With a rag generously soaked in the solution, thoroughly wipe all internal surfaces, including shelves, drawers, walls and the ceiling of the chamber.
Particular attention is paid to hard-to-reach places, ventilation holes and sealing rubber bands on doors, where dirt and mold most often accumulate. After chemical treatment, the surfaces must be washed with clean water and wiped dry with a clean rag, after which the doors are left open for ventilation and the smell of the disinfectant disappears.
⚠️ Attention: Do not turn on the refrigerator immediately after washing if the smell of chemicals remains inside - this may impart foreign substances to the products taste and cause poisoning in children.
The external surfaces of the refrigerator, including door handles, which are the main place where germs accumulate, are wiped with a disinfectant solution at least twice a day. Handles should be smooth, without notches or relief where dirt could get stuck.
Requirements for cleaning equipment
To maintain sanitation in a kindergarten, increased requirements are placed on cleaning equipment. All buckets, basins, rags and brushes must be made of materials that are resistant to disinfectant solutions and easy to clean. The use of wooden equipment, which absorbs moisture and dirt, is strictly prohibited.
Each piece of equipment must have a clear labelingindicating its purpose (for example, “For refrigerators”, “For floors”, “For tables”). This rule prevents cross-contamination: the rag used to wash the floor should not be used to wipe the internal shelves of the refrigerator.
After use, the equipment is soaked in a disinfectant solution, thoroughly rinsed and dried in a specially designated place, protected from dust. Storing wet rags in closed cabinets or buckets is unacceptable, as this promotes the growth of bacteria.
What to do with worn-out equipment?
Rags with irremovable contamination, torn or that have lost their absorbent properties must be disposed of. Buckets with cracks or chips must also be replaced, since dirt accumulates in the defects and cannot be washed out.
Table: Comparison of popular disinfectants
The choice of a specific product depends on the epidemiological situation, the type of contamination and the logistics of the institution. Below is a comparative description of the most commonly used drugs, allowing you to make an informed choice.
| Name of the drug | Active substance | Efficacy | Features of use |
|---|---|---|---|
| Diseffect | Chloractive component | High (bactericidal, virucidal) | Requires careful rinsing, may have a pungent odor |
| Alaminol | HR + alcohols | High (broad spectrum of action) | Washes off well, less aggressive to metals |
| Septodore | HR | Medium/High | Has a deodorizing effect, economical |
| Hydrogen peroxide | Oxygen | Medium | Safe, but requires high concentration for disinfection |
When working with any chemicals, personnel must observe personal safety measures: use rubber gloves, safety glasses and a mask if necessary. The concentration of the working solution should be checked with indicator strips or prepared strictly according to measuring tapes.
Documentation and quality control of cleaning
In a kindergarten, any process related to the safety of children must be documented. The main document confirming the completion of cleaning work is the general cleaning log. It includes the date, time of start and end of work, the name of the product used, its concentration and the name of the performer.
Control over the quality of cleaning is carried out by the medical worker of the institution or the production manager. They check the absence of visible dirt, plaque, mold and foreign odors in the refrigeration chambers. The results of inspections can also be recorded in a rejection log or a separate control sheet.
If violations are detected, such as the presence of mold in seals or an unpleasant odor, a report is drawn up and repeated disinfection measures are carried out using stronger drugs or mechanical cleaning.
How often should the solution in the wiping container be changed?
The disinfectant solution in the surface wiping container must be changed as it gets dirty, but at least once per shift. If during operation the solution becomes cloudy or visible particles of dirt get into it, it should be replaced immediately, even if the shift has just begun.
Is it possible to use a steam cleaner for refrigerators in a kindergarten?
The use of steam cleaners is allowed only if this is permitted by the instructions for specific refrigeration equipment and does not lead to damage to electrical parts. However, the main method of disinfection in kindergartens is chemical, using registered products, since steam may not provide sufficient exposure time for the death of all types of microorganisms.
What to do if mold appears in the refrigerator?
If mold is detected, it is necessary to urgently empty the chamber, mechanically remove plaque, then treat with a 1-3% solution of chloramine or another strong fungicidal agent with increased exposure. After this, the surfaces are thoroughly washed with water and dried. Products that were in the chamber must be destroyed.
Do you need to wash refrigerators after each use?
After each use (stacking/removing products), only visual inspection is carried out and, if necessary, spills are removed. A full wash with detergents is carried out daily at the end of the shift, and thorough disinfection is carried out weekly during general cleaning.
