The holes, inner wall, outer wall, water tray and air filter need to be cleaned and disinfected in steps, and they need to be cleaned at least once a day. First, focus on cleaning the drainage holes, which requires using a brush designed for this purpose to scrub up and down inside the hole.
Second, use a dedicated rag to carefully clean the inner wall of the hand dryer first, and then turn to the outer wall. To avoid confusion, the rag should be clearly marked to ensure that it is not mixed with rags for food contact surfaces. After cleaning, the inner wall, outer wall and drainage holes of the hand dryer should be fully disinfected with disinfectant alcohol. This step is crucial because many companies often overlook this key link.
Third, turn to the cleaning of the water tray and air filter. Before cleaning, pour out the accumulated water. Then, use a brush designed for non-food contact surfaces to clean thoroughly.
Finally, it is essential to stipulate the cleaning frequency. It is recommended to thoroughly clean and disinfect the hand dryer at least once a day. For the inner wall, the frequency of cleaning and disinfection can be flexibly adjusted according to the microbiological monitoring. In addition, a validation plan for cleaning and disinfection of hand dryers can be developed to ensure that the cleaning effect meets expectations.
