The McKee's 37 Sio2 Auto Wash 144 oz. Refill Kit Includes:

McKee's 37 Sio2 Auto Wash, 16 oz. + 128 oz.

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!

Threaded Refill Funnel

The Threaded Refill Funnel makes refilling your waterless wash spray bottle easier than ever before. Featuring staggered threads that fit virtually any bottle from 4 - 35 ounces, a refill is as easy as screwing on a cap! The ingenious design even features a spout on the side so that if you accidentally overfill your spray bottle, you can simply pour any excess back into the gallon bottle without making a big mess. The convenient hook allows you to store the funnel on the gallon bottle itself so you'll always know where it is.

3 x Premium Gold Microfiber Towels, 16 x 16 inches

The Premium Gold Microfiber Towel is made of incredibly soft and plush microfiber in a handy 16 x 16 inch size. It's perfect for quick detailing and pampers every surface it touches. The Premium Gold Microfiber Towel measures 16 x 16 inches and features an outstanding 70/30 blend of polyester and polyamide. The microfiber's weight is 380 g/m², making one very soft, thick towel!

Premium Chenille Wash Mitt

Premium Chenille Wash Mitt features hundreds of luxurious chenille fingers to make washing your vehicle safer than ever before. Each 'finger' holds tons of soapy wash solution, providing ample lubrication as you swipe over the surface of your vehicle. Since the chenille strands are plenty long, they pull any dirt and grime away from paint, diminishing the risk of wash-induced swirl marks.

    like being able to suds up car and rinse.


    Good Shampoo but just OK foaming & slickness

    Good shampoo, although it does not foam as thick as other brands and not as slick as other brands I've tried

    Works Well but Keep It Wet

    Cleaned well. Lots of suds. Based on several uses, I recommend keeping it wet and blow drying for best results.


    Works great

    Great car wash to use with the coating.
