The most popular foam gun on Amazon right now is the Foam King Foam Gun, which costs just under $40 at the time of this writing (and down to around $30 when it’s on sale.) I decided to give it a try. As you can see, my project Audi TT has not had a car wash in a pretty long time. Tons of dirt is sitting atop the car, so a pre-soak is just what the doctor ordered.

When I’m washing a car, one of the things that keeps me from taking out my foam cannon is having to lug out the power washer and hook everything up. If there’s no reason to pull out the foam cannon, I’d almost always rather use the Two Bucket Wash Method alone. However, sometimes the vehicle may be a bit dirtier and may require pre-soaking with car soap. A foam gun such as this MATCC/MATCEE can be a good alternative to a foam cannon as it can produce extra suds, although certainly not as much as a foam cannon produces.

Car wash soaps come in a variety of formalations with some car soaps offering characterstics such as extra lubricity, additional gloss, and additional suds. In the case of Chemical Guys Honeydew Snow Foam, it is a car wash soap that offers more soap suds more than your typical car wash soap. This makes it an excellent candidate for use in a foam gun, especially in a foam cannon.

Here is a list of car wash soaps that are ranked by the most recommended by auto detailers and detailing enthusiasts in various car detailing forums. It is impossible to know what is “the best” car wash soap out there as it really depends. However in my opinion, I would trust the recommendations of the folks who use many of these products on an everyday basis and therefore can make working comparisons across the field. Without further ado, here is the list of the best car wash soaps based upon recommendations that come up time-and-time again.

Washing your car is fundamental to maintaining your vehicle whether you’re doing an occasional maintenance wash or getting the vehicle ready to perform a more involved detail. The main purpose of washing the exterior is to remove light contaminants on the surface of the paint. This is done as a general car wash to make your car look clean again, but it also prepares your car for more detailing if you decide to go that route.
