COVID-19: correct cleaning of surfaces



The fight against viruses

It is not yet known exactly how long the coronavirus COVID-19 survives on different surfaces. However, since coronaviruses are “enveloped” viruses, it can be assumed that they can survive on surfaces for about four days, i.e. they are still infectious during that time. However, according to the Robert Koch Institute (Germany), the respiratory infection via droplet transmission is decisive for the spread of coronaviruses. Contact infections via viruses that have survived on surfaces are theoretically possible. Nevertheless, with this article we would like to underline how important the cleaning of surfaces is in the fight against viruses.

The following points should be observed in regard to our products:

  • All standard cleaning products can be used.
  • It is important to use only the correct quantities and to dilute the product correctly. Furthermore any liquid residue should immediately be dried up.
  • Neutral detergents (PH7) should be used to clean the aluminum parts.
  • No organic solvents should be used on painted aluminum components.
  • Never use any abrasive products to clean the trolleys.
  • No acetone, gasoline, chlorine, iodine or diluents should be used on plastic parts.
  • Never use acids or alkaline substances on the aluminum parts.
  • It is recommended to test the cleaning product on a small hidden surface first (e.g. the back side) before using it on the trolley.

Do it right!

  • Disinfection by wiping

    Disinfecting surfaces by means of wiping creates a simultaneous, synergistic cleaning effect. Wipe disinfection is therefore also the most effective method. The direct contact guarantees an even, targeted wetting of surface dirt and contaminants.


    For correct implementation, coarse impurities should be removed in advance with a disinfectant-soaked disposable cloth. Apply constant light pressure when wiping and disinfect the surface without gaps.

  • Spray disinfection

    With spray disinfection, we are talking about a very simple procedure, because unlike wipe disinfection, no such high intensity of work is required. Surfaces that are difficult to access are simply sprayed: application and drying time do not take very long.


    With spray disinfection, surfaces must be small, clean of gross dirt and dry. The spray must completely cover the surface. The surface must remain moist during the application time. Solvent-sensitive surfaces should not be considered for this disinfection method.
