Good Housekeeping (https://bit.ly/2Tj0Av0) published a helpful article with links to original scientific articles that provides our latest understanding of the times that particles can stay infectious on various surfaces. The bottom line, as we get into this expected fall/winter surge and although we believe that most transmission is direct human to human from droplets and aerosol coronavirus particles, we should keep wiping down surfaces to avoid catching the virus to do our part to avoid overwhelming hospitals and the unknown long-term consequences of exposure. Furthermore, if you can hold out from infection this fall/winter, you will give us more time to further develop, approve and stockpile effective treatments and vaccines. See below for the full link to the Good Housekeeping article and the amount of time COVID is suspected to last on various surface types.

© Design: Laura Formisano How Long Does Coronavirus Last on Surfaces? New Evidence Suggests 28 Day Window
Plastic: Research suggests that SARS-CoV-2 can be detected anywhere from 3 to 7 days, and the latest evidence stipulates that infectious virus may persist up until 28 days on non-porous plastic surfaces.
Metal: On copper, researchers established that viable virus wasn't detected on this particular metal after 4 hours. Other evidence suggests that stainless steel and metals can play host to the virus between 3 and 7 days.
Paper: While the Lancet study determined that SARS could be detected on paper money for up to 4 days after first exposure, money was one surface that successfully held onto the virus in the 28-day range in the Virology Journal findings. The Lancet also determined that virus particles couldn't be detected on printed paper or tissue paper after 3 hours.
Glass: Initial evidence suggested that virus could be detected on surfaces like windows or our screens on televisions, computers, or smartphones for up to 4 days.
Cardboard: Food packaging and shipping boxes were initially subject to debate at the onset of the pandemic, as people disinfected their shopping when they returned home. The NEJM study suggests that viable virus couldn't be detected on cardboard after 24 hours, meaning you might be able to quarantine your shopping outside of the kitchen until then.
Cloth or non-porous surfaces: While evidence has been limited on this category, the CSIRO team's research found that common cotton didn't hold onto the virus beyond two weeks (most of which was inactivated upon first contact).
