Rain boots might be plain, functional galoshes with no purpose other than keeping your feet dry, or they can be expensive, stylish rubber or vinyl boots that add flair to your wardrobe. Either way, your boots look better when they're bright and clean. Scuff marks, usually from accidentally rubbing against a dark surface, are unsightly, extremely noticeable and difficult to remove. Clean away the scuff marks so your boots will be ready for the next rainstorm.
Combine water with a small amount of chlorine-free scouring powder or baking powder to make a mild abrasive paste.
Dip a moist sponge or soft cloth in the paste. Scrub the scuffed area gently until the mark is no longer visible.
Remove the paste with a clean, damp sponge, and then dry the boots with a soft cloth.
Treat rubber rain boots with rubber conditioner after every cleaning to keep the boots supple and prevent cracking. Apply the conditioner to the boots with a soft cloth, and use a clean cloth to remove the excess. Let the boots dry overnight before wearing.
