SiO2 Auto Wash

17 reviews

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.

    WOW! Mckee's 37 Sio2 auto wash is AWESOME!

    I used it today for the first time & all I can say is WOW! I have a side gig as a detailer.& sometimes keeping my own Charger & Challenger up to my standards can be challenging. I already have them both coated with Hydro Blue pro. Being able to use the auto wash in direct sunlight without worrying about water spots while I wash both vehicles at the time is a game changer. The lubricity was phenomenal! The shelves in my garage are fast becoming dominated with Mackee's 37 products.

    SIO2 wash

    Have been using Sio2 wash for over a year. You notice the slickness immediately. Perfect wash for ceramic coatings. In full sun 90f, no water spots. Great product. Pair with hydro blue pro for superior water beading and protection.


    I really enjoy using the SiO2 car wash creates great suds and leaves car shiny

    You gotta try it to believe it.

    I will admit I have tried a lot of other auto wash and I had been using Rain X wash spotless wash. Rain X is no good. So I was watching TV and seen the McKee's 37 and decided to try it. All I can say is I have found Magic in a Bottle. I washed my SS Camaro with the SiO2 Auto Wash going on 3 weeks ago and it has rained and stormed within the last 3 weeks and my Camaro still looks amazing. I have no spots or streaks and I even washed my car with a heat index of 100 and sun beaming down on the car.
