We dont really have the virus issue up here but we have had a few cases, mostly in Eastern Washington where the climate allows for it.
Usually I start with the shop vac sucking up everything I can see. Then I throw on the respirator and fire the back pack blower up and get at all the hard to get spots.
A few goes back and forth between the two and youll pretty much knock all the loose stuff out and then you can get at the scrubbing.
