Buying replacement mobo. Tracking indicates shipment from China. How do I sterilize it so as to avoid the Coronavirus?
Alcohol bath? Hydrogen peroxide? (Will either of these damage components?) Bake it (what temp is safe but effective? There is a plastic shield on it)
Alcohol bath would do nicely... but just splashing a bottle over the board is sufficient. DO NOT use hydrogen peroxide (I'm not sure what it would do, but it's not a good sterilizing solution anyway). Afterwards, let the board air dry for at least a day. You can speed that up considerably with a warm fan (like a blow dryer). While it may appear dry much sooner you can't always see the wet spots in the tiny crevices.
BTW, read up some on how long the virus remains viable on surfaces. I seem to remember reading it's only like 2 or 3 days, but check that for yourself. And also consider that workers in factories generally wear gloves for handling parts. I'd really be more concerned about the outside of the packaging it got shipped in because of all the handling it gets and contact with other packages in the shipping containers. If you really feel it necessary to be uber careful I'd say just wear nitrile gloves, even for receiving and opening packaging, and not touch mouth, nose or eyes until you've taken them off and washed hands.
EDIT add: so based on article linked by USAFRet: it looks like simply leaving the box sitting in a nice, warm, sunny spot for a few hours will reduce risk even should the driver of the delivery van have been a carrier. That sounds like a typical Amazon delivery: drop the package on the porch in a sunny spot so anybody passing on the street can see it. hah. There ya go, Bezos had our best interests in mind all along.
