What is the best way to disinfect facilities for SARS-CoV-2/COVID-19?
Disinfection may reduce the spread of COVID-19 in public spaces, however, when using disinfecting solutions in collection spaces it is important not to splash or touch collection materials with the clearing solution, which may cause damage to items.
An effective cleaning solution can be made by combining 30% water and 70% ethanol or isopropyl alcohol in a clean spray bottle. Take care when purchasing isopropyl alcohol as it may already be diluted; Concentrations of alcohol below 70% are not strong enough to be effective, and concentrations of alcohol above 80% will evaporate too quickly to be effective.
If using a commercial cleaning product, select one with no fragrances and dyes, and one that requires the least amount of contact time. The EPA has compiled List N: Disinfectants for Coronavirus (COVID-19), which provides a list of products and contract times, as well as a guide on safe disinfectant use, Six Steps for Safe & Effective Disinfectant Use (PDF).
The CDC has created a general guide for disinfecting facilities, which includes tables, doorknobs, carpets, electronics, and textiles: Interim Recommendations for US Community Facilities with Suspected/Confirmed Coronavirus Disease 2019.
