SiO2 Auto Wash

The best wash for a coated vehicle!

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!

Paint Coatings are more prevalent than ever, because they outlast a traditional car wax while providing far superior protection against the damaging effects that a daily driver is exposed to. Our Paint Coating, for example, forms a thick shell of protection that lasts well over two years; it's so easy to use that you can apply it in your garage  - professional experience not required! Paint Coatings exhibit very unique characteristics, which is why we developed a premium auto wash designed to maintain the glassy shell of protection.

McKee's 37 Sio2 Auto Wash gently cleanses your vehicle of dirt, grime, and road film without compromising the protection or water beading of your paint coating. In fact, this sio2-enhanced formula fills in any microscopic fractures in the coating, restoring the gloss without altering the surface tension. Even though modern-day paint coatings exhibit a self-cleaning affect, you still need to properly maintain them using a manufacturer-approved auto wash!

Stop worrying about water spots! Instead of washing your vehicle one panel at a time and then rinsing it off, wash the ENTIRE vehicle using Sio2 Auto Wash and THEN perform your last and final rinse. This is made possible thanks to the non-alkaline, pH-balanced formula. Water, not auto wash, creates water spots! WARNING! Don't try this with any other auto wash except McKee's 37 Sio2 Auto Wash!

McKee's 37 Sio2 Auto Wash is extremely concentrated. Just an ounce or two of this thick, watermelon-scented shampoo creates mounds of thick, frothy suds.

    The best

    I’m own a mobile detailing business and use the SiO2 wash on every vehicle. It leaves a great protective layer even on uncoated vehicles. Big bonus is during the summer you don’t have to race to rinse it. SiO2 Auto Wash Review

    Amazing stuff

    I'm a detailer for a living and have switched from the extreme foam soap to this for all of my washes. It does a great job on non coated cars as well as coated, my customers can really tell, this combined with SiO2 tire shine and you got a shine like no other!

    Best there is, period!

    Pay attention to what McKees say about this product: "leave it on the car while you finish. No reason to rinse off halfway through a large vehicle. The soap is better to leave on than clear water." (all paraphrased) This is and important reason why this SiO2 Auto Wash is so great, you are adding protection while washing, and it's designed to work in any conditions and to make things as easy on the customer as possible. I wash my entire truck and don't have to worry about this soap drying. If it does no big deal. Love this car wash soap.

    Being able to wash the car safely in the sun is an absolute game changer. Waiting for shade meant very late dinners on wash day. Now that I can start washing earlier in the day I no longer need to delay dinner!
