1. Clean the windows as soon as possible. The longer the saliva stays on the window, the harder it is to remove and more likely it is to cause stains on the window. Tinted windows tend to stain easier than untreated windows because the film is on the inside of the car, and the saliva sits on the film causing stains rather than on the window itself.
2.Mix vinegar and water in equal parts in a spray bottle and use it like standard window cleaner. The vinegar helps to cut through dog slobber and remove any stains left.
3.Dip a Mr. Clean Magic Eraser in hot water and squeeze out the excess. Scrub the window. If any dog slobber remains, spray with the vinegar and water mixture and use the sponge to scrub the solution on the window to remove the rest of the slobber.
4.Use a rag to wipe Pine Sol on the windows. Allow the cleaner to remain on the window for a few minutes and rise with warm water. Finish with window cleaner to remove any of the cloudy film that remains and get a streak free finish.
5.Spray Goo-Gone on the windows. This cleaner, designed to remove sticky substances, also helps remove thick and stubborn dog slobber and helps to remove stains. Rinse the windows with warm water and finish with window cleaner.
