Demand for disinfectants has exploded due to the COVID-19 pandemic. While the use of disinfectants is essential to prevent the spread of the virus, it is also essential to be aware of the role of ordinary detergents in cleaning surfaces and how we can enhance the ability of a disinfectant to kill harmful microbes.

To understand this, it is useful to go through the basics of washing and cleaning chemistry as well as the criteria for choosing the right substance.

• Broad definition of dirt: any interfering substance in the wrong place. For example, food turns into a stain when it is on a shirt

• Dirt can be solid or liquid

• Dirt may be water-soluble or insoluble in water

• Contamination usually takes place in two ways:

1. Transporting from a dirty surface in contact with another surface


2. Landing directly from the air to the surface

• Dirt adheres to the surface by electrical forces, medium, or chemical reaction - or all of the above

Properly selected chemistry and adequate mechanics are required to clean the dirt. In the case of cleaning the surfaces of a home or other public space, a substance that can be wiped or rinsed off after a period of exposure is needed to break down fats and proteins that bind bacteria and viruses.

The rationale for basic or general cleaning of surfaces prior to disinfection is based on the following:

• The disinfectant must be allowed to have direct contact with the surface of bacteria and viruses.

• Organic contaminants, including detergent residues, can interfere with or neutralize the effect of the disinfectant.

• The detergent can have an advantageous effect on the surface charge and energy state from the point of view of disinfection.

If the surface to be cleaned and disinfected is particularly dirty, water rinsing is recommended to remove loose dirt particles. This is especially important if strong detergents have to be used to prevent interfering chemical reactions.

 Choosing the right type of detergent

Different types of detergents on a chemical basis affect the effectiveness of a disinfectant in different ways. The following factors should be taken into account when choosing a detergent:

• pH: the pH of the working solution should be close to neutral (5 to 9), so that the detergent solution does not react or neutralize the disinfectant. For example, Pineline Super Wash and Pineline Universal Cleaner are good choices.

• Rinsability: avoid detergents containing gel-like or abrasive substances so that no disinfecting residues remain on the surface to be washed. All Pineline products are liquid and do not contain abrasives.

• Antibacterial detergents reduce the effectiveness of the disinfectant. Pineline products do not contain anti-bacterial substances.

• Enzymes: It is a good idea to check with the detergent dealer that the enzyme-containing detergent is compatible with the disinfectant used.

• Ammonia-based substances can react with disinfectants, especially chlorine-based bleaches to form gases that are hazardous to breathing. Pineline products do not contain ammonia.

• Acids: Acidic detergents should not be used with chlorine-based substances. Pineline Acid Cleaner or Pineline Super Cleaner is not recommended for use with chlorine-based disinfectants.

• When using other strong detergents, it is recommended to dilute the substance sufficiently to adjust the corrosivity and pH to near neutral. For example, when using Pineline Metallic Cleaner, Pineline Pressure Wash HD and Pineline Heavy Duty, a very dilute working solution is recommended if disinfection is performed after washing.

Detergent concentrate, ready-to-use cleaning agent or cleaning cloths?

Detergents and cleaners are sold as concentrates, ready-to-use solutions and pre-soaked in cleaning cloths. The use of concentrates, ie detergent concentrates for dilution, is recommended, as this makes it easy to control the concentration of detergent in terms of washing result and disinfection efficiency. The ready-to-use spray detergent also more easily leaves active substance residues, which can serve as a new growth medium for microbial growth.

In addition to choosing the right product type, it is a good idea to follow the cleaning and disinfection instructions provided by the authorities and professionals in the fight against a pandemic.
