There are more important reasons to clean your boots after each use than just ensuring your significant other doesn’t gripe at you for tracking mud and muck into the house. Leather that isn’t cared for is more likely to weather and crack than properly treated leather. First on the list of boot-maintenance to-dos is using a good brush or boot cleaner when you get home to get all the dirt and other residue off. To remove grease or oil, sprinkle baking soda or cornstarch on the area, rub it gently with a wet rag, and let it sit overnight. Later, wipe off the powder with a soft cloth. For other stains, mix equal parts lemon juice and cream of tartar into a paste, apply it to the stained area, and let sit for a half hour. Then, use a damp cloth to remove the paste.
