Yes, if you are referring to the small aerosolizers that are just inside the faucet head, they can be hrs to remove. Is getting new faucets a possibility? That might involve plumber costs. I have read that some people put vinegar in plastic bags and tie it to the faucet. Not as easy as it sounds.

Our daughter and son-in-law live outside of Boston in a small, 2-story 1940s home with the original oiler. They changed all the A/C system and redid the kitchen, but this was after we first visited. I was exposed to very old plumbing and air units along with all the old dust while there. It is possible that I already had this bug or at least bronchiectasis then without knowing it.

I find myself nervous now about visiting family, especially the ones with big, beautiful, loving and very hairy ones. I was always a dog cuddled but now find myself wondering what they rolled in or stepped through. This bug changes your approach to many things. That is a hard one for me.
