Outdoor areas generally require normal routine cleaning and do not require disinfection. Spraying disinfectant on outdoor playgrounds is not an efficient use of disinfectant supplies and has not been proven to reduce the risk of COVID-19 to the public. You should maintain existing cleaning and hygiene practices for outdoor areas. If practical, high touch surfaces made of plastic or metal, such as grab bars and railings, should be cleaned routinely. Cleaning and disinfection of wooden surfaces (e.g., play structures, benches, tables) or groundcovers (e.g., mulch, sand) is not recommended.
