Frequently Asked Questions about Car Wash Soap

As the saying goes, if you want something done right, you’ve got to do it yourself. While taking your wheels down to the local automated car wash is often the easiest option, but a hand wash is usually the best option for many reasons. Washing your own car is less likely to cause damage, less expensive and results in a cleaner car.

Here’s a look at common questions about using car wash shampoo to keep your car clean:

What Do I Need to Wash My Own Car?

The basics are simple, but each detail does matter. Choosing the right equipment makes a big difference, as the right car washing car gear makes the job easier and more effective. Here’s what you need:

Car Wash Soap

All of the car wash soaps listed in our guide have plenty of benefits. But no matter which one you choose, only use a soap specifically made for cars. Avoid using household products like detergents or dish soap, which can damage and scratch the paint.


Along those same lines, don’t use a kitchen sponge or other sponge you might have sitting around the house. Instead, use a high-quality sponge made specifically for use on vehicles. Non-abrasive, they won’t scratch or otherwise harm your vehicle’s paint, windows or finish.

Aside from a sponge, you can also find plenty of car wash mitts, which you wear like a mitten. Both sponges and mitts are able to soak up large amounts of soap and water for fast, easy cleaning. You can also use the same sponge or mitt to wash the wheel wells.


Avoid air drying your car, as that can lead to water spots and general dullness. While towels made specifically for washing cars do exist, any microfiber towels will work fine. The tiny fibers in these towels dry without scratching, while cotton towels can actually trap small bits of debris which then rubs against your car’s paint.


The size varies based on the size of your car, although 3.5 gallons is pretty standard (unless you’re washing a bus, semi or anything else unusually large). Plastic is usually the better choice than metal, as metal buckets can develop rust and corrosion over time, which can scratch your car.

Most automotive experts recommend the “two bucket method” when washing your car. As the name implies, this method uses two buckets. One bucket is filled with soapy water while the other is filled with clean water used to rinse the car. You might have to refill the “rinse bucket” with clean water a few times during the wash.

If you really want to protect your car against scratches, get a grit guard for your bucket. This simple sorting devices helps push dirt, stones and other heavier material down to the bottom of the bucket. If you only dip the sponge into the upper part of the bucket, you can avoid accidentally collecting potentially sharp objects.

Water Hose or Power Washer

In a pinch, you can simply pour soapy water over your car and go from there. But if you want to give your car the best clean possible (and isn’t that the point?) then you want to use either a water hose or a power washer.

You can use any type of spray attachment for your garden hose. A wide, gentle spray is usually the best option. Avoid any spray which is too focused and intense. Not only does the smaller coverage area make the washing process longer, but a focused line of water can potentially damage your vehicle.

Don’t use a power washer unless you’re familiar and experienced with using them. The risk of accidental damage is fairly substantial when using a power washer on your car – especially if you’re not familiar with how they work.

What’s the Best Process for Washing My Car?

Once you’ve gathered up the right materials, the actual washing process should be quick and easy. Basically, washing your car is really no different than washing your hair.

Step One: Find a Great Washing Spot

Park your car in a cool, shaded location. You want the car’s exterior to be relatively cool to the touch as well. Ideally, you’ll want to park the car on a flat location, so water doesn’t run across the car in just one direction.

Step Two: Prepare Your Materials

Each car wash shampoo will have specific direction for use. Generally, you’ll add one ounce of soap for every gallon of water. Remember to use two buckets – one with soapy water and the other with clean water.

In most cases, the water from your tap will be fine. However, so-called soft water can be a problem in some cases. Many people find that soft water leaves behind water spots on your car, although other people have no issues. If your area has soft water you might want to use some distilled water instead.

Step Three: Rinse the Car with Clean Water

Next, you’ll want to cover the car with clean (non-soapy) water. You can spray the car with a hose or power washer or use a sponge to cover the car manually. Get a nice coating of water across the entire car. This washes away loose debris and dirt without scratching the surface.

Step Four: Wash the Car with Soap

Now you’re ready to wash the car. Using your sponge or mitt, gently scrub the entire surface of the car. Use the two-bucket method to keep sharp objects out of your sponge.

Step Five: Rinse the Car (Again) with Clean Water

Next, you’re ready to rinse. While a sprayer will work, the best option is usually just the regular output of your garden hose. Rinse your car from the top down. Allow the water to cascade gentle down the car to wash away all the soap away uniformly, which helps reduce water streaks. Most car soap is safe to wash down the storm drain.

Finally, you’re ready to dry. You want to dry your car as quickly as possible. All water contains at least some mineral deposits. If the water is allowed to air dry, those minerals will remain on the surface and potentially create water spots. Using a microfiber cloth, gently but quickly dry your car immediately after rinsing.

How Often Should I Wash My Car?

Experts typically recommend washing your car once a week. Although that might seem like a lot, there are several benefits to a weekly wash.

Contaminants take a little over a week to damage most car paint. Two major hazards are bird droppings and insect remains. As they break down, they release complex proteins and organic acids which can cause corrosion and discoloration.

Another potential hazard is brake dust, an invisible chemical by-product which can coat your car and corrode the paint. Driving in traffic will cause brake dust to build up on your car.

The good news is that all of these potential hazards need to stay on your car for an extended period of time to cause damage. Which means a weekly car wash will generally remove all of these contaminants harmlessly.

Can I Use Dish Soap to Wash My Car?

Dish soap manufacturers design their products to cut grease and grime on pans. You may think that a dish soap that can handle a tough-to-clean pan also has the cleaning power to work for a dirty car. However, it is usually the best policy to use car soap to wash your car rather than dish soap.

Dish soap is good at breaking down burned-on grease because it is an abrasive soap. Such products may leave your car looking clean in the short term, but they can also speed up the oxidation process and cause the car’s paint to lose its shine. Also, if you wax your car, you should not consider dish soap.

Again, dish soap is supposed to break down materials that coat dishes. Therefore, it will break down car wax. Even if you apply wax afterward, the residue from the dish soap will make it more difficult for the wax to coat the car.

Why is car soap better? Car soap contains ingredients that make it smoother than dish soap. It is not abrasive, so it slides easily across the car’s surface. Furthermore, car wash soaps work with other auto products such as wax.

How Do I Avoid Swirl Marks When I Wash My Car?

Swirl marks often occur when grit gets stuck in your sponge when you wash your car. The grit can leave tiny scratches after a wash. You can avoid this by rinsing both before and during the washing process.

First, you should thoroughly rinse your car before you apply any soap. You can use a hose to remove any visible dirt and to spray water on the entire car. When you apply the soap, you can occasionally pause to rinse your sponge. You can either spray it with a hose or dunk it in clean water. Doing this helps you remove any particles that could scratch your car.

Sometimes swirl marks do not come when you scratch your car with pieces of grit. Instead, they come from using the wrong kind of soap. Perhaps you use low-quality car soap or dish soap. These leave a deposit that does not rinse away. You can see the residue in circles on your car. Luckily, these kinds of swirl marks are easy to avoid. All you have to do is purchase quality car soap.

What is a Waterless Car Wash and Does It Work?

A waterless car wash involves using a chemical cleaner with lubricant. These cleaners isolate and remove dirt on a car. You typically spray them on and then wipe them off with a cloth after they have had time to cling to the grime and dirt.

Waterless car wash products can be useful and convenient. When you do not have time to perform a deep clean with a sponge and hose, you can opt for one of these products. However, not all deliver on their cleaning promises, and many people consider them as a supplement to traditional sponge-and-car-soap cleaning rather than a full replacement.

Final Thoughts

The local car wash down the street isn’t doing your vehicle any favors. For the absolute best results, you’ll want to wash your car yourself by hand. A hand wash removes more dirt and grime while also reducing the potential for scratching.

The right equipment makes an important difference. Using our guide above to select the perfect car wash soap. When you chose the right car wash soap, your car will look better than ever!
