I had my house excavated around the whole perimeter to replaced weeping tile and waterproof the foundation. There is clay left on the asphalt driveway and I would like to clean it as walking on it and having your shoes full of it is not pleasant. What would be the best tool to use for the job? Should I do it on a day when it;s try and use and Powerbroom? If so, would rubber paddles or bristles work best for the type of work on an asphalt driveway?
