Guidance from the government:
COVID-19: cleaning in non-healthcare settings
“Public areas where a symptomatic individual has passed through and spent minimal time, such as corridors, but which are not visibly contaminated with body fluids can be cleaned thoroughly as normal. All surfaces that the symptomatic person has come into contact with must be cleaned and disinfected, including:
- objects which are visibly contaminated with body fluids
- all potentially contaminated high-contact areas such as bathrooms, door handles, telephones, grab-rails in corridors and stairwells
Use disposable cloths or paper roll and disposable mop heads, to clean all hard surfaces, floors, chairs, door handles and sanitary fittings. Any cloths and mop heads used must be disposed of and should be put into waste bags."
