Darn SoCal "hard" water!!
I got my car just last week and I decided to wash it yesterday underneath an overcast day. I completely forgot how bad the water spots are due to the hard water in So Cal. What should've been a quick wash and detail became an all afternoon event as I worked my butt off getting off the water spots. I clayed most of it out, but I ran out of time to clay the entire car. Any suggestions on how to beat this next time? My neighbor recommended this Mr. Clean attachment to the hose. Any other ideas?
