What does cleaning mean?

Through cleaning and hygiene, it seeks to eliminate microorganisms from the skin and from objects that are in contact with humans. Cleaning products are those that help remove dirt, such as detergent, bleach, ammonia or soap


What is disinfection?

Disinfection is a process that consists of cleaning different surfaces and objects in order to prevent possible infections by pathogens such as viruses, bacteria or protozoa. Among the chemical disinfectants in water, the most common are chlorine, ozone and chloramines.

Disinfection types

Chemical disinfection

This type of disinfection is used in delicate spaces such as hospitals, nursing homes, food industries or places with a high traffic of people such as schools, shopping centers, banks, etc.

I don't know

Depending on the microorganism to be destroyed and the level of disinfection required, different types of chemicals are used.

I don't know

Some of the chemical disinfectants that are used are:

I don't know

  • Chlorine

  • Sodium hypochlorite

  • Chlorine dioxide

  • Chloramines

  • Hydrogen peroxide

  • Copper / silver ionization

  • Bromine

  • Ozone

  • UV

Physical disinfection

Physical disinfection includes methods that use heat, autoclave, moist heat, or ultraviolet light.

What is used for disinfection?

Se denomina desinfección a un proceso químico que mata o erradica los microorganismos sin discriminación (Tales como agentes patógenos) al igual como las bacterias, virus y protozoos impidiendo el crecimiento de microorganismos patógenos en fase vegetativa que se encuentren en objetos inertes.


The importance of cleaning and disinfecting

Cleaning is a process where we dissolve or suspend dirt, generally with water supplemented with detergent. Disinfecting, on the other hand, involves removing microorganisms from surfaces with chemical agents.


Differences between cleaning disinfection

Washing (cleaning) and disinfecting are two different things. Cleaning refers only to the use of soap and water to remove dirt and most germs. Disinfection, on the other hand, refers to the use of cleaning solutions that contain ingredients that kill bacteria and other germs.



Coronaviruses are transmitted in most cases through large respiratory drops and transmission by direct contact.

The survival time and conditions that affect the viability in the environment of the virus that causes the disease COVID-19 are currently unknown. According to studies evaluating the environmental stability of other coronaviruses, it is estimated that the coronavirus of severe acute respiratory syndrome (SARS-CoV) survives for several days in the environment and the coronavirus related to respiratory syndrome in the Middle East (MERS-CoV) more than 48 hours at an average ambient temperature (20 ° C) on different surfaces.

I don't know

Due to the possible survival of the virus in the environment for several hours, facilities and areas potentially contaminated with the virus that causes the disease COVID-19 must be permanently cleaned, using products that contain antimicrobial agents known to be effective against coronaviruses. .

It is necessary to adopt all the necessary security measures before, during and after executing the activities leading to the cleaning and disinfection of sites potentially contaminated or contaminated with the virus that causes the disease COVID-19. This protocol is based on current knowledge about the virus that causes COVID-19 disease and evidence from studies on other coronaviruses.



Provide guidance for the process of cleaning and disinfecting public spaces and workplaces (excluding health care facilities).



This protocol will be applied to the cleaning and disinfection of spaces for public use and workplaces, excluding health care establishments, because there are specific protocols that contain guidelines for cleaning and disinfecting this type of infrastructure.



  • Before carrying out the disinfection, a surface cleaning process must be carried out, by removing organic and inorganic matter, usually by friction, with the help of detergents, then rinsing with water to remove dirt by dragging.

  • Once the cleaning process has been carried out, disinfection of already clean surfaces must be carried out, with the application of disinfecting products through the use of sprinklers, towels, fiber or microfiber cloths or mops, among other methods.

  • The most widely used disinfectants for environmental use are solutions of sodium hypochlorite, quaternary ammonia, hydrogen peroxide and phenols, and there are other products with less experience in their use.

  • For surfaces that could be damaged by sodium hypochlorite, an ethanol concentration of 70% can be used.

  • It is possible to use another type of disinfectant, in which case it is recommended that the recommendations of the disinfectant manufacturer should be followed for its preparation and application.

  • When cleaning chemicals are used, it is important to keep the facility ventilated (eg opening windows, if feasible) to protect the health of cleaning personnel.

  • To carry out cleaning and disinfection, the use of disposable utensils should be privileged. In the case of using reusable utensils in these tasks, they must be disinfected using the products indicated above.

  • In the case of cleaning and disinfecting textiles (for example, bedding, curtains, etc.) they must be washed with a hot water cycle (90 ° C) and add laundry detergent.

  • Priority should be given to the cleaning and disinfection of all those surfaces that are handled by users with high frequency, such as: handles, handrails, toilet bowl, water faucets, table surfaces, desks, support surfaces, among others. .



The use of the following Personal Protection Elements (PPE) should be considered when carrying out cleaning and disinfection work in public spaces and workplaces (excluding health care establishments):

• Disposable or reusable bib

• Disposable or reusable cleaning gloves: resistant, waterproof and long-sleeved (non-surgical).

Cleaning and disinfection must be carried out using the personal protection element described above, which must be correctly put on and taken off.

In the case of using reusable PPE, these must be disinfected using the products indicated above.

For the proper removal of PPE, it should be done avoiding touching the outer (contaminated) face of gloves and bibs with bare hands, and considering the following removal sequence:

  • Remove bib and gloves simultaneously

  • Perform hand hygiene

In principle, it is assumed that the waste derived from cleaning and disinfection tasks, such as cleaning elements and utensils and disposable PPE, can be eliminated as assimilable solid waste, which must be delivered to the municipal waste collection service, making sure to arrange them in a double resistant plastic bag, preventing their contents from dispersing during storage and transfer to an authorized final disposal site.

In the case of other residues derived from the disinfection process, such as infectious or dangerous residues, they must be eliminated in accordance with the regulations in force for these types of residues: Regulation on the Handling of Residues of Health Care Establishments and Sanitary Regulations On the Management of Hazardous Waste, as appropriate.



The employer must develop a safe work procedure, which establishes the forms of work and preventive measures in attention to the products used, in accordance with the provisions of this protocol.

I don't know

It must be available at all times to be presented to the health authority when it requires it, as well as the means of verifying the training of the workers who will carry out these tasks.

Special attention should be paid, in those areas where it is certain that a suspected or confirmed case has remained, where its use should be avoided until its complete cleaning and disinfection in accordance with the provisions of this protocol.
