Clear View
It can be extremely aggravating to try to see through foggy glass, especially if the fog is present in an important location such as your glasses or the mirrors of your vehicle. Dish soap is the answer to permanently removing that annoying fog from your life once and for all.
Start with a little bit of dish soap and dilute it with some water to make it more manageable. After that, rub the mixture onto any glass surface, such as your eyeglasses, the mirrors in your car, the windows in your house, and so on. Because the dish soap prevents condensation from forming on the surface, you will maintain an unobstructed view at all times. If you want to remove the fog from your shower door, you could even try applying some dish soap to it first.
