The coronavirus appears to stick to surfaces of varying intensity, and some materials are easier to clean than others. According to the preliminary findings of the study led by the University of Tampere, the cleaning agents used also affected the results.
The study was a joint project of the University of Tampere and companies, the aim of which was to collect evidence-based information on the effectiveness of various cleaning agents in removing coronaviruses and other pathogens from surfaces. The results of the study are intended to help the restaurant, tourism and catering industry during and after the Covid crisis.
In laboratory experiments, different surfaces were contaminated with endemic coronavirus samples and then cleaned with various cleaning agents. The researchers found that none of the methods were completely effective.
"In general, it can be said that disinfectants were the most effective cleaning agents. All detergents [tested] cleaned the virus surfaces moderately effectively. All in all, all cleaning agents played an important role in keeping the surfaces clean," Sami Oikarinen, says a senior researcher at the University of Tampere.
The researchers also studied the effectiveness of cleaning agents in the wards treating Covid-19 patients at Tampere University Hospital.
The study found that cleaning reduced the amount of viruses on the surfaces of the hospital environment, but did not always remove them completely. But according to the researchers, because of their low concentrations, the virus left on the cleaned surfaces using any of the substances tested is not enough to cause infection.
The study found that the risk of infection was lower in a restaurant environment when diners were placed farther apart and when buffet cutlery was changed to clean every half hour.
The partners in the study are the University of Tampere, Tampere University of Applied Sciences, Kemvit, Berner, Kiilto Clean, Poistoa and Norlandia Care, as well as other domestic partners.
The researchers said the research results would be published later.
