Question: How to grocery shopping cart or  trolleys be disinfected to slow the spread of COVID-19

Answer passage (source: WHO):
page_title: Q&A: Considerations for the cleaning and disinfection of environmental surfaces in the context of COVID-19 in non-health care settings
section_headers: What is the guidance for the disinfection of outdoor spaces such as open markets, roads?
section_content: In outdoor spaces, large-scale spraying or fumigation in areas such as streets
or open market places for the COVID-19 virus or other pathogens is not
recommended. Streets and sidewalks are not considered as routes of infection
for COVID-19. Spraying disinfectants, even outdoors, can be noxious for
people’s health and cause eye, respiratory or skin irritation or damage.  
This practice will be ineffective since the presence of dirt or rubbish for
example, inactivates the disinfectant, and manual cleaning to physically
remove all matter is not feasible. This is even less effective on porous
surfaces such as sidewalks and unpaved walkways. Even in the absence of dirt
or rubbish, it is unlikely that chemical spraying would adequately cover
surfaces allowing the required contact time to inactivate pathogens.
