How do you get dishwasher detergent off your car windows?

Dish soap is a degreaser, which means that it can break down grease and grime. This makes it an effective way to remove many different types of stains, including dishwasher detergent stains. To use dish soap, simply mix a few drops of dish soap with warm water and apply it to the stained area. Scrub the area with a soft cloth until the stain is gone. Rinse the area thoroughly with water and dry it with a clean cloth.
