I've been off work for a couple of weeks and, yes, we have a sprinkler system that usually runs while I'm at work, and it's hit my car a few times. The water here is very hard and water spots are a big problem. Took it to the car wash today and apparently it's been too long because they didn't come off (usually if I take it within a day or two it's not a problem). So what is the best way to get rid of these? I've read that vinegar or a paste of vinegar and baking soda will work, but I'm sort of afraid to do that. Any thoughts?
