Hi all, I've run into an issue with car cleaning that I was hoping some knowledgeable people here might be able to help me with. Long story short, my mom - who knows nothing about cars - last week saw that my glass was dirty and tried to clean it without my knowledge. She took a bucket of hard tap water and rags and smeared the dirt around, leaving it to dry in the sun. I washed my car properly today but mineral spots remained on the front, back, and passenger windows. Is there a reasonable way to get them cleaned off? I'm pretty frustrated and have no idea why anyone would try to touch a high-end car without the owner's permission. This hasn't even been the first time. I've also once caught her trying to wash my car with a hose and rags. Had I not coincidentally been nearby, she would have gone through with it. Thanks in advance!
