This is one of the strangest recipes we’ve come across and one of the most surprising, too! Basically, you rub soap onto the mirror, I used sunlight soap, then wipe away the residue with glass cleaner, I used Wendyl’s. And then, for some strange reason, after fogging up the whole bathroom by showering—the mirror remains un-foggy! Who would have thought something so simple and seemingly counter-productive could work so well? I did this three weeks ago and both mirrors in the bathroom remain fog free!
