Over here, with the dust and all, cars get dusty and dirty fast. Car-washing is hard work. I used to send my car to one of those auto-washers but I don't anymore because I find that those brushes do scratch the paintwork. It's easy to get your car washed here as there are lots of car-wash stations.
I was shocked when a colleague confessed that her car is seldom washed. Her secret? She has been using car covers all this while. Maybe I need to invest in one.
