Best Car Wash Soap Buying Guide & FAQ

If you want to wash your car on your own, you need to find the best car wash soap. It’s less aggressive than generic soaps such as laundry detergent or dish soap. You can find basic options, no-rinse soaps, and soaps with additives. Read this guide and learn what you should consider when buying the best car wash soap.

What to Look for When Buying the Best Car Wash Soap

Here are some of the things that you should look for in the best car wash soap.


Look for soap with a biodegradable formula. This kind of formula breaks down easily and won’t leave a mess on your turf. It won’t cause damage to the soil and grass. Just read the product description before buying the soap. You can also ask the seller about this matter or check it online.

pH Balance

General soaps can damage the car’s wax sealant and remove its protective barrier. The best car wash soap contains non-abrasive ingredients. The soap’s pH balance should be neutral as well. This kind of soap won’t leave acidic residues on the vehicle. Reputable car wash soap manufacturers state this information on their website or bottle. If the pH balance of the soap is not stated on the bottle, you should conduct your research online before buying it.


It pertains to how slippery the soap is. Slippery soap makes it easier to loosen grime or dirt. It’s also easier to wash or rinse out your car. Moreover, the soap is less likely to leave residues in the car.

Tips for Buying and Using Car Wash Soap

When looking for the best car wash soap, you should consider its foaming property, concentration, value, and scent. A soap that produces a rich and thick lather can effectively suspend dirt particles without extra scrubbing. This can help reduce damage to your car’s surface.

The soap should have long-lasting suds, and it should be eco-friendly as well. Of course, you want to get the best value for your money. Consider buying soap in a 64-ounce bottle because it lasts up to 1 year. The formula’s pH level should be considered too because it determines the soap’s alkalinity or acidity.

Alkalinity effectively breaks up acidic grime or dirt. An extremely low pH level and extremely high pH level could corrode the wax, coat, and paint of the car. Look for car wash soap with a neutral formula that has some alkalinity.

The soap’s streak resistance and water spots should be considered as well. If the soap leaves water spots, streaks and swirls behind, the vehicle will look dirty. It will also damage the car’s paint. The soap should be quick-drying to avoid these problems. 

You should also consider the soap’s scent, especially if you’re suffering from breathing problems or allergies. If you can’t find a scentless soap, you can consider sweet-smelling ones such as lemon or cherry.

Once you’ve found the best soap, you should know how to use it in order to get a professional-looking car wash job. The two-bucket technique prevents swirls or streaks. Fill one bucket with clean water for rinsing and the other with soapy water.

Wash the tires first because you can easily remove any dirt or grime later. Start lathering the soapy solution on a different area of your car using a microfiber wash mitt. Dunk the mitt into the bucket with clean water to make sure that no loose dirt is picked up. Wring the mitt and repeat the same process until the whole vehicle is covered with the soapy solution.

Use a hose to remove the soap and rinse out the vehicle. Don’t put a nozzle on your hose. Begin hand drying your car with a drying cloth after rinsing it. This will help prevent water spots from forming.
