According to my quick research, disinfecting an enveloped virus can be achieved by simply taking its lipid spikes and protein envelope apart.
Therefore "anything that can dissolve fat and protein structure"[¹] can be used to disintegrate (disinfect) the virus permanently, such as soap + water, alcohol, heat, UV, bleach, etc.
[¹]: This is my interpretation, therefore automatically includes eg. lining spray as the disinfectant, which may or may not be true.
Quote from cdc.gov:
Cleaning staff and others should clean hands often, including immediately after removing gloves and after contact with an ill person, by washing hands with soap and water for 20 seconds. If soap and water are not available and hands are not visibly dirty, an alcohol-based hand sanitizer that contains 60%-95% alcohol may be used. However, if hands are visibly dirty, always wash hands with soap and water.
Quick internet search (eg. nih.gov) shows that ethyl alcohol and isopropyl alcohol can be used as the mentioned "alcohol". However, I can find no information about usability of methanol.
Regardless of the toxic nature, can methanol be used to disintegrate the virus structure (as disinfectant)?
