1. Types of Car Wash Soaps

There are four common types of soaps you can use to wash your vehicle.

  • Conventional Car Wash Soap. This is your plain car wash soap with no extras. It simply foams and helps you get the dirt off your car. It can be scented or colored, though.
  • Car wash Soap with Conditioner. This second type of car wash soap will both clean and condition the vehicle's surface. An excellent example of this is the Meguiar's G7101FFP.
  • Car Wash Soap with Wax. With this type, car detailing entails cleaning dirt from your car and protecting the paint job with a wax layer. Wash and wax soaps like Turtle Wax T-472R will save you the extra time you need to wax the car.
  • No-Rinse Car Wash Soap. Another revolutionary and time-saving feature of auto wash soaps is the no-rinse feature. When using a no-rinse soap like the Optimum NRWW2012Q, you can skip the rinsing part and just buff the car clean and dry.

2. Concentration & Dilution

Another important factor to pay attention to is the wash shampoo's concentration. This is because 1 gallon of concentrated soap wash offers better value than 1 gallon of a diluted version of the same soap.

As it is challenging to measure each car wash shampoo's concentration, the next best thing is to pay attention to the manufacturer's guidance on dilution.

The more water you can add to the soap, the more concentrated it is and the longer it lasts. A good dilution ratio is 1 fluid ounce of washing soap to 1 gallon of water.

3. Foaming Properties

Another vital quality of a washing soap is the type of lather it makes. You want a soap that produces foam that is as thick and rich as possible.

The lather is what determines how effectively the soap will pick up dirt particles. An excellent example of this is the Karcher 9.558-146.0that provides a rich and luxurious foam to loosen and remove dirt quickly.

4. pH Level

pH is a measure of the alkalinity or acidity of a solution. You want a shampoo formula that is neither too acidic nor too alkaline, but still slightly alkaline.

A slightly alkaline solution breaks up dirt easily. On the other hand, if the soap is too alkaline or acidic, you run the risk of damaging your car's paint job. Hence, you are better off with a pH-neutral product like the Chemical Guys CWS_110.

5. Eco-Friendliness

If you care about the environment, you should go for 100% biodegradable car soaps. With such soap, you can clean your ride with a clear conscience, knowing you will not hurt the environment.

6. Water Spot & Streak Resistance

You will find lots of car soaps leaving water spots and streaks after washing, and also find those that dry off quickly, leaving nothing behind.

The best car wash soaps are those that do not leave any water spots or streaks behind. These products ensure you end up with a more pleasant appearance and minimize the buffing you need to do afterward.

7. Scent

Different car wash soaps and shampoos come with different scents like lemon, orange, and berries. The choice here is personal as it is only you that knows the kind of smell you like.

That said, something with a pleasant scent like the Chemical Guys CWS_101 is always more favorable as it leaves the vehicle smelling great for a long time after the wash.

Must-Have Items for Washing a Car

  • Sponge. You need a quality sponge such as those made from microfiber, wool wash mitts, and sheepskin. The sponge should be firm enough to clean the car and soft enough not to scratch or damage the paint job in any way.
  • Brush. Although you could also use a sponge, a brush remains the best tool for washing your car's tires. Soft bristles don't work well, so go for one with medium-strength or stiff bristles.
  • Buckets. You need at least two buckets to wash a car effectively. The first bucket is for the soapy water, while the second is for the clean water for rinsing.
  • Drying Towel. There are different types of drying towels and their alternatives out there. These include chamois, water blades, squeegees, and microfiber towels.
  • Wheel Cleaner. This one is optional because you can clean your wheels with ordinary soapy water.
  • Bug & Tar Remover. This is another optional item, and it is useful when you want to remove bugs and tar from the surface. Just spray the bug and tar remover on your car, give it a few minutes to work, and then wipe with a cloth.
  • Wax. If you love your car's paint job and want to maintain the shine for as long as possible, you need to wax it from time to time to protect the glossy top-coat.
  • Polish. If the top coat does happen to get dull, then you need to polish the area. A polish is simply a fine abrasive that evens-out the tiny imperfections on your car's top coat to bring back its shine.

Here are the steps to follow when cleaning your vehicle.

Step 1: The Pre-Wash

Before starting with the wash, make sure the engine is cool and that the car isn't under the hot sun.

Step 2: Wheels First

After spraying the entire vehicle with water, you should first wash the four wheels and tires before the car body. This is because you don't want your wheel-wash solution splashing on your paint job and probably not getting washed off if you wash the wheels after the body.

Step 3: The Right Mix

Before washing the car, make sure you mix the soap according to the manufacturer's directions. Doing this ensures you get the potency right for the best results.

Note: You need at least 2 buckets to properly clean your car. One bucket contains the soap mix, while the second is for clean rinsing water. You can even have a third one for the tires if you want.

Step 4: Wash & Rinse in Parts

Once you are all set up, start to wash and rinse the car in parts. You don't want the soap drying on the car, so try cleaning a door or two at once, then rinse the area off before moving to a different spot.

Step 5: Final Rinse & Drying

After washing and rinsing the car, you can now give it a general rinse with a hose, for instance. Next, you should dry the vehicle. Dry it as quickly as possible and make sure no water dries on the car. Here you can use drying towels or blades.

Step 6: Wax & Polish

The last phase for a perfect car cleaning session is waxing. Waxing is optional and offers no immediate visual improvement to your car's paint job, but it does protect the top-coat.

FAQs

Do Different Colored Cars Need Different Types of Soap?

A: Most car wash soaps are safe for all vehicle colors. In case a particular soap is meant for a specific color like black only or dark colors, the manufacturer often makes this clear in the description.
