The link below would be a good place to begin planning for museum cleaning and disinfecting. That guide from the Minnesota Historical Society provides enough detail to help identify some general practices and some things to avoid. One of the latter is spraying or fogging rooms with disinfectant, "a potentially dangerous practice that has no proven disease control." Of course, there is more being learned and published as the course of the pandemic proceeds, so it makes sense to read new and updated recommendations from the Centers for Disease Control and the National Institute of Health. One very useful bit of information is the observed life of the virus on surfaces; I am not offering the figures for that, but once you determine it from an authoritative source, you can make decisions about objects and surfaces that may not need disinfecting. To reiterate the main point, fogging and wide-area spraying in museums is regarded as potentially dangerous. Under similar circumstances, I have observed the destruction of particularly sensitive museum materials.
In general, the MHS publication requires: "Damp cleaning methods must be used where possible for dusting surfaces [including floors]." By those means, there is less likelihood of stirring up dust or aerosols that may carry the virus. As for cleaning non-porous historic materials, some conservators recommend isopropyl alcohol for most surfaces, but
not for shellacked or varnished wood. I feel this is a bit too vague, and the Minnesota Historical Society guide offers a few more specific instructions, as well as places to seek further details. Look to the experts, in both health and conservation fields.
Best,
Bruce

Subject: Disinfecting From COVID-19 - Halosil?
Good Evening, Everyone.
I am the Chief, Museum Support Center, Fort Belvoir, VA. My particular facility is a collections storage facility, but we are headquarters to forty some Army museums across the world. We are looking at the possibility of using Halosil to disinfect from COVID-19. Has anyone looked into this? What are your thoughts?
Specifically, (1) is this something we can/should use in our museums or will it potentially harm artifacts/exhibits/art and (2) if this is a bad idea, what other means are there to achieve his intent without harming artifacts/exhibits/art?
The link to the product is Delivering a Broad Spectrum Disinfectant across Facilities
It's a proprietary product.
I sincerely appreciate any commentary you can provide.
Thank you.
Carrie
