McKee's 37 Sio2 Auto Wash was formulated for the unique cleaning requirements of vehicles that are coated with a paint, wheel, or glass coating. This thick, luxurious shampoo creates mountains of foamy suds that encapsulate dirt and grit particles, leaving behind an extremely glossy finish! You can confidently use McKee's 37 Sio2 Auto Wash in direct sun because this pH-balanced, non-alkaline shampoo contains water-softeners that reduce spotting. Works equally well on non-coated vehicles as a gloss-enhancing auto wash. Your vehicle has never looked this good after a simple wash!
