@Christine455 For me, the main point is that we don't have a situation in our homes that would contribute to disease transmission. All those cleaning protocols are supposedly designed to achieve that end, and quite honestly there are hosts who don't even clean adequately, let alone have any knowledge of how to make sure they aren't running a super-spreader rental. So some hosts probably should just be following the protocol to the letter, because they are clueless about cleanliness. Better safe than sorry.
I don't even have a dryer- I line dry everything. And my washing machine has never been hooked up to hot water. The water that comes out of the cold tap is more like tepid, as it comes from a big black tank on my roof.
But I know that soap and water deactivates the virus, that it doesn't live on porous surfaces like cloth, for more than a day, max, and that the UV sunlight on the linens hanging on the line for a day or two also sterilizes. And I have enough bedding and towels that I'm never just putting the same bedding back on the bed that the last guest used, even after it's washed. It's going to be sitting there clean and folded in a plastic tote in my laundry room for at least a week or more before being used again.
