Have you every walked into your bathroom and the soap scum on the bathtub door was so distracting to the eyes that you missed the jetted tub that was to the left? As a seller, here is an easy tip to keep those shower walls and windows clean, so that your potential buyers see the whole bathroom, not just the little piece that did not shine.
After cleaning the bathroom, head into the garage and grab a bottle of the rain repellant, made for car windows. Spray the product on the surfaces, creating an invisible barrier, keeping the water and soap scum off. This barrier should make your glass surface sparkle and add a twinkle to the buyers eyes.
