When you start cleaning your warehouse/garage, start cleaning all the high surfaces. That includes cleaning/dusting off air ducts, upper windows/frames and the top of the pallets and racks/shelves. This way, debris will fall to the lower levels allowing you to pick it up as you make your way down. It’s a best practice that will help you avoid having to clean the floor twice over. For best results, we recommend using at Sani Marc an extension pole with a duster head and an industrial-grade vacuum cleaner.
