The authors show that, depending on the material and the conditions, human coronaviruses can remain infectious from 2 hours to 9 days.
At temperatures of around 4°C or 39.2oF, certain versions of the coronavirus could remain viable for up to 28 days. At temperatures of 30–40°C (86–104°F), coronaviruses tended to persist for a shorter time.
At room temperature, a coronavirus responsible for the common cold (HCoV-229E) persisted significantly longer in 50% humidity than 30% humidity. Overall, the authors conclude:
“Human coronaviruses can remain infectious on inanimate surfaces at room temperature for up to 9 days. At a temperature of 30°C [86°F] or more, the duration of persistence is shorter. Veterinary coronaviruses have been shown to persist even longer for 28 d[ays].”
When the scientists delved into the literature on the persistence of coronaviruses on different surfaces, the results were variable. For instance, the MERS virus persisted for 48 hours on a steel surface at 20°C (68°F). However, on a similar surface and at the same temperature, TGEV survived for up to 28 days.
Similarly, two studies investigated the survival of two strains of SARS coronavirus on a paper surface. One survived 4–5 days, the other for just 3 hours.

These coronaviruses can linger on surfaces for over a week but that some of them don't remain active for as long at temperatures higher than 86 degrees Fahrenheit (30 degrees Celsius). The authors also found that these coronaviruses can be effectively wiped away by household disinfectants.
For example, disinfectants with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite (bleach) can "efficiently" inactivate coronaviruses within a minute, according to the study
