Yes I know and combine that with other toxins they’ll blame it on. Food, water, air, to get the tracking off them.
Speaking of carrots. I have a friend and recent widow in the South who’s water pressure is low and can’t even wash her cloth as if the door is open to add more the water drains out. That’s when she found out what she suspected was water pressure. They tend to get a build up of rust in South Texas. Apparently it can get pretty thick. I found that 1/2 and 1/2 vinegar and water is the least toxic way and there are products but don’t know if it can damage the pipes. Have you ever come across that. She just had other repairs plus a new washer so she don’t need another big bill again especially pipes.
