Which type of soil does the Shampoo Service guarantee to remove?

The Shampoo Service is designed to effectively address common cleaning challenges in vehicles, particularly focusing on dirt and average soils that accumulate in everyday environments. This includes the removal of most mud and dirt that can easily soil upholstery and carpets. The emphasis on "most" highlights that while the service is robust, there may be rare exceptions depending on the severity or nature of the stains.

Grease stains are generally more complex due to their consistency and may require specialized treatments beyond standard shampooing. Pet hair, while also a common issue, can often necessitate specific tools and techniques that are different from what a shampoo service alone can provide. Similarly, heavy rust deposits typically require focused corrosion removal methods, as rust is not something that a shampoo treatment could effectively address.

Thus, the Shampoo Service’s guarantee pertains primarily to those moderate soil types that are frequently found in vehicles, making it the most appropriate choice for the question posed.
