I can recall as a player leaving my boots muddy and wet in a plastic bag to be dried and "cleaned" later. Didn't get to clean them and a few days later, I had to wear them in match - cold, wet and heavy. Yuks, not nice!! I never did it again and I always encourage my players to clean their boots the minute they get home. and remember not to dry your boots in the sun. Air them out somewhere in the house but not in direct sunlight. This will make your boots last longer.
