HOUSEHOLD HINTS: Steamy mirrors got you down in the morning? Are you tired of trying to shave in a fog? Sick of always cutting large gobbets of flesh off your face simply because you don't have time to wait for the mirror to defog? Well, friends, I have an answer to all of your excess humidity questions. If you rub just a little amount of dishwasher fluid on the mirror in your bathroom, it will not fog up for a few days. Just another household hint from The Passing Parade.
