How do I disinfect surfaces with WDS?

Surface disinfection is the control of microorganisms on surfaces, such as tables, floors, instruments and rooms. Here are five steps you can follow to properly disinfect surfaces with Watter Disinfection Solution (WDS):

  1. Get the disinfectant: Get WDS when you want to kill bacteria, viruses, fungi and/or yeasts.
  2. Clean the surface: Remove any dirt or dust from the surface before you start disinfecting. This can be done with water (and/or detergent) and a cloth, for example.
  3. Apply the disinfectant: Apply the WDS and make sure the surface is completely covered with the agent.
  4. Allow the agent to act for five minutes.
  5. Dry the surface: Allow the surface to dry completely before using it again. It is also possible to dry the surface using, for example, a clean cloth.

It is important to remember that disinfectants are only effective when used correctly. Be sure to follow the instructions on the label and cover the surface completely with the disinfectant. For more information, it is wise to visit the RIVM website.

room disinfection

Fogging rooms with HOCl

Watter produces a disinfectant based on water, salt and electricity. The disinfectant has been extensively tested and is effective against micro-organisms. The main active substance in the disinfectant is HOCl (what is HOCl?), which is friendly to humans, animals and the environment. Both as a liquid and as a mist. An emerging trend in Europe and particularly in Asia is the ultrasonic fogging of HOCl in spaces to disinfect both air and surfaces. Independent research has shown that HOCl not only disinfects surfaces, but also tackles aerosols. It has also been shown to achieve sufficient log reduction to prevent contamination and spread. These studies can be sent on request.

Humidifiers specific for HOCl

The disinfectant produced by Watter has a slightly oxidising effect. This means that not every nebuliser is suitable to be used in co-operation, because parts can rust and the device will break down quickly. Therefore Watter recommends room disinfection systems that are especially developed for the use of HOCl. We do not produce these ourselves, but we work with a party that can provide this for you. Of course we can send you the contact details on request.
