If you want a shampoo that can handle hard water and direct sun with ease, Adam’s New Car Wash Shampoo is just what you need in your detailing arsenal. Read my in-depth test to see why I placed it as my favorite car shampoo on the market right now.

How We Tested Adam’s New Car Wash Shampoo

First, I diluted Adam’s New Car Wash Shampoo according to the individual instructions, opting for a medium dilution ratio where a range was suggested. Next, I observed the amount of foam it produced and assessed how slick it felt on the panel. I’m looking for a product that produces a good amount of foam in the bucket, and one that performs well on the paintwork. Finally, and most crucial, I carried out a visual and physical inspection to see how much dirt, if any, was left after washing. It’s worth noting that I also took the price point of the shampoo as well as how much shampoo is needed per wash into consideration in my verdict.

Adam's New Car Wash Shampoo review

First Impressions

Adam’s eye-catching label immediately gets your attention. I love the pull-up dispenser, which makes pouring and measuring Adam’s New Car Wash Shampoo that much easier. The bright blue liquid has a wonderful Wildberry scent that makes it smell good enough to drink. But refrain from doing that, please.

Features

Adam’s New Car Wash Shampoo has a couple of tricks up its sleeve that really make it worth your attention. First of all, you can use it in direct sunlight, which is something most shampoos warn against. This means that even if you don’t have any shade, you can happily wash your car, even in the middle of summer. Secondly, Adam’s says its New Car Wash Shampoo will not water spot, even when washing with hard water. And of course, it’s pH-neutral, as you would expect, making it coating-safe.

What’s It Like To Use Adam’s New Car Wash Shampoo

You can use this shampoo as a pre-wash snow foam, but I’ve tried it’s not got enough muscle for that. Just stick to using it purely as a shampoo and you will not be disappointed. The preparation process is a little different.

Rather than just pouring Adam’s New Car Wash Shampoo straight into a bucket, you pour it straight onto your wash mitt. Then you put this in your bucket and pour the water directly onto the mitt. I’m not sure what the point of that is, but who am I to go against the instructions? It does mean that the first time you apply your wash mitt to the paint, it’s absolutely loaded with shampoo, which can only be a good thing.

You need 1-2 fl. oz per wash, which is about average, and you can easily stick to just 1 fl. oz if your car isn’t especially dirty. As promised, there’s loads of foam, and it hangs about for ages. On the panel, it feels lovely and slick, and it’s a pleasure to wash with.

On very hot days and in direct sun, it will dry on the bodywork, but there’s no residue left after rinsing and drying the car. You don’t have to fight against stubborn spots, everything just wipes away, so it really does do what it promises to do.

Adam’s New Car Wash Shampoo Verdict

Adam’s New Car Wash Shampoo really is excellent. Full disclosure, I’ve been using this shampoo myself for years now. It’s been my personal summertime go-to shampoo and it’s never let me down or left me disappointed. There’s honestly nothing I don’t like about it. I highly recommend this shampoo.
