It all started with Tim. He's a Griot's Garage customer who loves their Microfiber Dry Towel but doesn't like staining his towels when he dries those tricky, hidden dirty areas of his vehicles, like wheels, doorsills, gutters, trunk and hood channels, doorjambs, etc. So we created a less expensive, smaller towel just for these areas that always have a little dirt and grime, even after a good washing. This towel is a perfect size, 18" x 24", so it is easy to use. Super absorbent, waffle weave pattern holds more water than a traditional cotton towel. Thanks to Tim!
