1. Chemical Guys EQP_312 TORQ Professional Foam Cannon and Honeydew Snow Foam Cleanser

The Chemical Guys are one of the most trusted manufacturers of car care products. They have their own professional-grade foam cannon called the TORQ. It attaches to the wand of any pressure washer, whether gas or electric. It replaces the nozzle while you soap up the car.

The TORQ has a screw-on quart-size tank that you can fill with your favorite detergent. This particular package includes the Honeydew Snow cleanser. But you can also choose from other options like Meticulous Matte or Glossworks.

Once you’re ready to work with the foam cannon, you can adjust the spray angle and the amount of airflow. In this manner, you can change how sudsy you make the car.

The Honeydew Snow detergent sticks to dirt to lift it out of every nook and cranny. And both it and the foam cannon work with pressure washers down to 800 psi.

When you can’t make up your mind which detergent you want to use, try this kit from Chemical Guys. Not only does it come with the foam cannon, but it has three different car wash soaps.

The soaps include Glossworkz Auto Wash, Honeydew Snow Foam, and Citrus Wash and Gloss.

3. Chemical Guys CWS_110_64 Honeydew Snow Foam

We mentioned the Honeydew Snow Foam above, but let’s look at it in detail here. First off, this detergent creates an astonishing amount of suds.

The Gold Class Car Wash rinses clean and leaves a glossy finish. For best results, wipe your vehicle dry immediately after rinsing. Meguiar recommends using 100% cotton terry or microfiber towels.

Plus, it has water softeners so that it won’t streak or leave spots.

Chemical Guys recommend pre-rinsing, then covering the vehicle with thick suds. Use a foam cannon or the black tip and detergent hose on your pressure washer.

Only 1 ounce of detergent in a 5-gallon bucket of water makes a lot of foam.

Adam’s car wash shampoo promises you 110% satisfaction. The formula suspends minerals in the water to keep them from scratching the car or even the wax. It’s so slick that it removes dirt without letting it damage the clear coat. Additionally, the pH-neutral soap doesn’t dry out plastic or rubber.

Tips for pressure-washing your car

If you’re like us, you enjoy washing the car, or else you’d have someone else do it for you. Once you have a pressure washer, the fun goes up a notch. But for maximum enjoyment and professional results, invest in a foam cannon.

You might also find that accessories like a surface brush attachment help you remove road dirt and dead bugs more efficiently. But always make sure that the bristles on the brush are free of debris before you use it. The same is true for a washing mitt. Make sure it’s clean and not gritty.

Now, if you’re new to power-washing, you may not realize how close to disaster you are if you’re parked in the wrong place. It’s fine to wash your car in the driveway if your driveway doesn’t have gravel. If you hit gravel with a high-pressure spray, you’re likely to send pebbles flying. Also, park away from objects that you don’t want to get wet.

When you’re ready to begin, rinse the car first. You don’t need to, and probably shouldn’t use high pressure. Next, spray on a thick layer of suds with your foamer. Start at the top and work your way down. Then let the foam work for a few minutes – but don’t let it dry.

When you rinse, use a lower pressure setting and work from the top down. Pros will tell you that drying the car right afterward with a microfiber towel can help you achieve that showroom shine.


We hope you found your favorite new pressure washer detergent for your car today. We hope it makes taking care of your vehicle easier and more pleasurable. Visit us again soon to see new reviews of the best cleaning products and tools.
