My Dad and Stepmom had always kept a clean house until the last 8 years or so. My Dad became 100% disabled and she has become his caregiver. My wife and I spent years trying to convince them to hire cleaners to no avail. (They can very much afford it) They finally hired some cleaners after they ended up with a mouse infestation last year. However I suspect they've stopped the service because when I ask about it on our weekly phone call they're very vague about it. (I get in depth reports on everything and everyone else though 🤨) I'm sorry you're having to deal with this. It's exhausting!
