A \"fog scraper\" on a mirror in the bathroom

The windshield wiper is used to scrape the rain, not to scrape the mud, and we only see it on the windshield of the car. The designer has designed a \"wiper\" on the mirror in the bathroom. Every time we take a shower, the bathroom mirror is always foggy, and we need to wipe it with a handkerchief. However, after installing this \"wiper\", it is more convenient to simply rotate a little bit to remove the fog from the mirror.
