At our hospital, the sanitizers used steam cleaning and said it was the most reliable way to kill viruses from surfaces. At home, I also decided to use a steam cleaner and found a competent instruction https://www.fortador-usa.com/blog/does-steam-kill-viruses-how-to-kill-germs-with-steam-cleaning which tells how long does steam take to kill bacteria and viruses, as well as tips on choosing the right equipment depending on your needs. CJ used the simplest home version of the Fortador Volt Mini and was very pleased with the result. Recommend.
