Disinfecting cleaning of hard surfaces

For the chemical disinfection of contaminated surfaces, strategies are available to reduce transmission and infection. Kärcher offers products for the disinfective cleaning of hard surfaces, such as the disinfecting cleaner RM 732 and the disinfectant RM 735, both of which have virucidal activity against enveloped viruses. The new coronavirus also falls into this category.
