This cleaning set includes everything you'll need for basic polyester case parts cleaning! Designed for the field technician, this set includes three lint-free, 100% cotton, pre-washed cloths and glass water bottle spritzer. Not too big and not too small, the water bottle holds enough for an average week of field service. At the end of the week, simply throw the towels in the laundry and refill your water for the next week of service!
