Introduction

Restoring the exterior of your vehicle starts with a simple hand wash, and if done correctly, you'll achieve the clean and shiny look you're after. But where do you start? Well, you can't achieve the look you're after without the right soap! Throughout this article, I'll be covering the basics of car wash shampoos, what to consider when buying the right soap for your vehicle, and some frequently asked questions.


What To Consider When Choosing A Car Wash Shampoo

Scent

Choosing the right scent is completely up to you and has little to no effect on the performance or cleaning power of the product. Popular scents of car soaps are citrus, berry, or fresh linen. If you're someone who is sensitive to certain smells, you may want to opt in for a soap that doesn't include any type of scent at all.


Concentration

The significance of concentration in car wash shampoos lies in their effectiveness, cost-efficiency, and versatility.

I'll explain each point in brief...

  1. Effectiveness: Highly concentrated car wash shampoos are created with a higher concentration of cleaning agents. The higher amount of active cleaning agents results in more cleaning power. This allows the shampoo to break down dirt, grime, and road contaminants easier and more effectively leading to a more thorough deep clean.

  2. Cost-efficiency: Highly concentrated soaps allow for cost savings. Since this type of soap is highly concentrated and will allow for a greater dilution of water to the product, it allows you to use less product per wash making it a more economical choice over time.

  3. Versatility: Highly concentrated car soap allow for more versatility in terms of dilution ratios. The ability to customize the dilution allows you to adjust the strength of the cleaning solution based on the dirty your vehicle is. For light contaminants/dirt, you can use a more diluted solution, while for heavily contaminated areas, you can increase the concentration. This flexibility enables you to tailor the cleaning power to suit different cleaning needs and achieve optimal results.


Foam

The foam that is produced by car wash soaps is another important factor to consider. Choosing the right product that produces a good amount of foam allows you to get better coverage of application and it enhances cleaning performance. A car wash shampoo that produces rich and dense foam allows the cleaning agents to reach all areas of the vehicle, including the tight crevices and contours. The foam also lifts and suspends the dirt particles from the surface to prevent scratches and swirls when performing a hand wash.


pH Balance

The pH balance of a car soap is a significant factor to consider. A car wash shampoo with a balanced pH, typically around neutral (pH 7), provides gentle cleaning that effectively removes dirt and grime without being overly aggressive on the paint surface. If you were to choose an acidic product (pH <7) to clean your car with, not only will it remove any type of wax or sealant leaving it vulnerable to UV rays and oxidation, but it could also etch or corrode the clear coat. On the other hand, if you choose to go with an alkaline product (pH >7), it can cause staining, discoloration, or hazing to certain surfaces such as chrome or polished aluminum.
