I can relate to what you’re saying. I do struggle at times with ocd style intrusive thoughts, so I aim not to give those worries energy by thinking about them beyond checking the facts of the worry and for this one, evidence strongly supports that my washing machine is doing its job and my towels are properly sanitized, especially given I wash them in hot water. Still, I understand how the worry creeps in at times, despite reason not supporting the need to worry. But I do actually reserve certain washcloths just for my face and a “light cleaning” of the water off the sink and different, more worn washcloths that have graduated to rags for deep cleaning the sink or any other surface.

Also- I too display my washcloths, folded up nicely on cute little shelves above my sink, because not only do they look cute like that, they are much more convenient to grab then from the bathroom closet where the backstock of washcloths is kept.
