This funny grandmother reveals that Jet Dry and some dishwashing liquid are the winning combination when it comes to cleaning shower windows. She bought a wand for the dishes and replaced the sponge with a scratch-resistant scrubbing pad so as not to damage the glass. Then he put a teaspoon of dishwashing liquid on the wand, added a drop of Jet Dry and filled the wand with water for most of the trip. He then tipped the wand up and down to mix the ingredients.
