Car wash soaps are your vehicle’s first line of defense, consisting of highly concentrated, pH-balanced polymers and conditioners designed to protect your paint and cut through tar and road grime like butter. Some car wash formulas add a UV-resistant protective layer, activate water beading/sheeting for easy rinse-off, and even generate little sud action for a water-free option.

Best Car Wash Buying Guide & FAQ

Car wash shampoo, conditioners, and wax run the gamut in terms of the type of formula, concentration, thickness/consistency (foaming shampoo vs. rinse-free options), scent, and ingredients. Each combination works for one vehicle more than the other based on climate conditions, type of wax/exterior paint used, and other factors. 

Keep reading to learn more about the main factors to consider when purchasing a car wash, ranked in order of importance from most important to least important.

car wash soap

pH levels

pH levels speak to a formula’s alkaline or acidic content. The standard pH range goes from 0 (acidic) to 14 (alkaline), with 7 being the base, neutral score. Excessively low or excessively high pH levels could cause your vehicle’s paint and wax to corrode, especially in hot weather. 

Look for car washes with a pH level of 7. A pH level of 7 makes it safe to apply on all surfaces, including rubber, metal, chrome, and paint. Keep in mind that some car washes specialize in more aggressive cleaners (e.g., bug removal formulas like GYEON BUG & GRIME that carry pHs closer to 9). This buying guide is covering general car wash formulas only. 

Foaming Shampoo vs. Rinse-Free Options

Foaming car washes imply just that—rich, soapy suds that create massive bubbles when mixed with water. Foam does an excellent job of lifting up dirt, road pitch, and grime by softening and encapsulating it, making it easier to remove and rinse off. pH neutral foam also helps prevent scratching your car’s paintwork.

Rinse-free options are more designed for lighter cleaning and convenience. Rinseless washes are good for occasional dust build-up, not a vehicle soaked with road salt, grime, and dirt. It is a preferred method of cleaning for people who live in apartment complexes with no access to a driveway and a hose. 

Deciding between either one mainly comes down to the type of cleaning job (light vs. heavy), location (outdoors vs. in a garage), and desire to conserve water. 

Note, the appearance of swirl marks and watermarks also depends on the cleaning method. Automatic car washes produce swirl marks a lot more frequently than manual hand washes since many machines cannot touch hard-to-reach areas. 


The heavier the formula concentration, the longer it will last. As a rule of thumb, aim for car washes with a minimum soap to water ratio of 1 ounce for 2 or 3 gallons of water. Note, container sizes vary wildly, going as small as the 303 Ultra Concentrated Car Wash’s 18 ounces upwards of 100 ounces for the Rain-X’s Foaming Car Wash.  

Noting concentration levels will also help you know how long each container will last. Expect a 100-ounce container of car wash to last you for years, assuming a weekly or bi-weekly cleaning schedule. Many larger containers are also cheaper on a per-ounce basis than smaller containers. 


Car washes carry all types of scents. One of the more popular scents is citrus, common with naturally derived citrus-based formulas (orange oil). With fewer exceptions, car washes can come in cherry, lemon, pina colada, and vanilla scents with the occasional oddball (e.g. 303 Ultra Concentrate Car Wash’s bubble gum scent). 

Car wash scent is mainly a matter of preference and has no bearing on overall effectiveness. 

Auxiliary Features

Some car washes include detailing equipment, such as wash mitts, towels, and scratch remover. For beginner details, this could be of interest.

Notes on Car Wash Soaps

Look for car wash soaps with a Base 7 rating. The standard pH range starts at 0 (acidic) to 14 (alkaline). Car wash soaps with a 7 rating work on all kinds of surfaces, including chrome, glass, rubber, and wax.

Some car washes are specially formulated. This includes bug wash, a high alkaline product that may be heavy on ammonia. These are typically applied over a smaller surface area such as windshields and wheels to grind bugs out.

Do not use household cleaning agents like dishwashing soap to wash your car. These soaps contain properties that may strip off your vehicle’s protective wax and shorten the life of your paint job. Instead, look for a mild car wash product and apply using a dry microfiber cloth, lamb’s wool mitt, or soft sponge. Be sure to rinse your wash mitt thoroughly to avoid road grit scratches.

Be sure to work your car wash soap into a rich and foamy later before applying it to your paint. This helps to better lubricate and elevate dirt, grime, and other particles on your paint, making it easier to rinse off.

For a true, glass-like finish, you may need to take your car wash a step further and purchase a clay bar kit. Clay bar kits consist of synthetic clay that is rubbed and kneaded over your paint to remove embedded dirt. Remember, your typical car wash only works to remove surface dirt.

Equipment Needed to Wash Your Car

You will need the following equipment when washing your car:

Two buckets

The first and foremost thing you need is buckets. Fill one with soapy water and the other with clear water for efficient cleaning.


A hose is necessary when you want to rinse off the soap from your car.

Washing Mitt

Do not just use any cloth to lather on the soap. Instead, use a microfiber washing mitt. It fits your hand like a glove, literally, and prevents any abrasion. Alternatively, you could also use a car wash brush to clean your car.

Foam Gun

Instead of using your hands to lather on the soap to your car, you can invest in a good quality foam gun. It will spray thick lather directly on to the car quickly and efficiently.

Grit Guard

A grit guard can prevent loose contaminants from accumulating onto the wash mitt each time you rinse.

Drying Cloth

Drying cloth should be used after rinsing as you should never allow the soap to air dry.

5 Important Steps When Washing a Car

The two-bucket method will suit you best as it prevents any streaks or swirls. Fill one with soapy water and the other with clear water to use for rinsing. Follow these steps for a professional-looking wash job:

Step One: Wash Your Car Wheels

Wash your car wheels and tires first using a cleaner as you can easily wash off any dirt later.

Step Two: Use A Wash Mitt

Use a Wash Mitt to pick up the soapy solution from the bucket and start slathering it on to a different section of the car.

Step Three: Rinse The Wash Mitt In Clean Water Periodically

Dunk the Wash Mitt into the clear water bucket to ensure no loose contaminants are picked up. Wring it.

Repeat Steps Two and Three until your whole car is covered with the soapy water.

Step Four: Hose Down Your Car With Clean Water

Use a Hose to thoroughly rinse out your car and wash off the soap. Ensure there is no nozzle on the hose and the water can flow freely.

Step Five: Use A Drying Towel To Dry The Surface Of Your Car

Take a proper drying dowel and start hand drying the car as it prevents any water spots. You could also use a car dryer blower if you’re very serious about the process.

Car Washing Soap FAQ

Choosing the best car washing soap really depends on your needs. Some people will look for the best overall, while others will simply want something to protect the car’s paint job. No matter the case, we’ve got you covered.

Q: What do car washes use to remove bugs?

Dead bugs and their remains are extremely acidic to your car’s paint job and should be removed pronto. If that’s not feasible, they become dried and caked-on and can leave permanent damage, so to get them off, car washes use a special formulation of caustic pre-treaters to loosen dried bug guts prior to washing.  If you want to remove them at home, consider a product that’s specifically designed for bugs and tar, like the Chemical Guys Concentrated Bug and Tar Remover Car Wash Soap.

Q: What is a good substitute for car wash soap?

If you go out to your garage to prepare for a sunny Saturday morning car wash,  only to find that someone has used up the last of your favorite car wash soap and neglected to mention it, in a pinch, you can always use a mild dish soap. While it’s not specifically formulated for use on cars, most dish soaps don’t contain any abrasive or harmful agents that will damage your car’s paint or strip away waxes and sealants.

Q: What kind of soap do you use in a pressure washer?

Depending on what you want to wash, you could probably clean most things with dish soap and your pressure washer. If you want to use a car wash soap with your pressure washer, then these are the top-recommended options:

Q: What is the best wash and wax soap for cars?

Many car owners feel the best car wash soap comes with a layer of wax as well. Combining your car soap with wax not only cleans the car’s surface but it also protects the car’s paint from potential damage. These are the best car wash soap and wax options:

Alternatively, you could use something to clean the surface of your car, like Chemical Guys Mr. Pink Superior Surface Cleanser, and then pair with one of the best car waxes that we recommend.
