This is a growing concern but you can easily make your own cleaner with one part water to four parts bleach. The CDC recommends using bleach or ammonia/alcohol based products. We wipe down all hard surfaces as viruses "like" those more than soft, mop all floors, pay special attention to doorknobs, clocks, lamps, and the undersides of dining tables-- places guests touch that may not always be obvious. We do this anyway, but now have a check list of places we need to make sure to "get."
I had posted a while ago about dishwashers and got some push back but I will say it again-- dishwashers get your dishes cleaner and kill any pathogens by virtue of the fact that they use super heated water. Your dishes probably have the biggest potential to be used over and over, so we take special care to make sure that all dishes are sanitized by running even smaller loads through the dishwasher. Yes, its not ideal for water conservation, but a lot of things are not ideal right now.
Soft surfaces like sheets, towels, bedding, blankets, etc. get their normal wash and dry. Carpets are vacuumed between every guest and steamed once every other week. We only have throw rugs so I don't know how it is for those with wall to wall carpets.
I don't think this cleaning is particularly onerous as we already do a lot of what is recommended. Its just about making sure that you have a checklist of spots you need to pay extra attention to, and that you follow it.
