Please choose the correct ending to complete the given sentence: Youth: [header] How to keep white adidas superstar shoes clean [title] Pre-treat your shoes. [step] Before wearing your superstar shoes, treat them with a water and stain repellent. Spray the repellant evenly on the area of your shoe.

Ending1: Dab the excess repellant with a soft towel, and allow it to dry overnight. When the repellant dries, add a second coat. Ending2: In hot weather, rain, and even snow, apply a clear surface cream to your shoe to protect it from damage. If your shoes contain oils and cannot be lightly cleaned, you can still use a protectant with oil in it. Ending3: Mix equal parts vinegar and water, one part bleach, and a few drops of a liquid dish detergent. Apply a generous amount to the area, and allow it to sit for several minutes. Ending4: For example, if your shoes are painted a bright color, spray some decoupage fabric repellent on the area. This will help hold in moisture without drying.
