What kind of pH value indicates a neutral substance?

A pH value of 7 is considered neutral, indicating that the substance is neither acidic nor basic. This value represents a balance of hydrogen ions (H+) and hydroxide ions (OH-) in the solution. In the context of water, which is a common reference point for pH, pure water has a pH of 7, making it ideal for many cleaning applications, including carpet cleaning.

Understanding pH is crucial in carpet cleaning because different cleaning agents operate optimally at different pH levels. Acidic cleaners, which have a pH below 7, are effective for removing mineral deposits and certain stains, while alkaline cleaners, with a pH above 7, are better suited for breaking down greases and oils. A neutral pH cleaner minimizes the risk of damaging sensitive fibers or altering the color of the carpet, making it a safe choice for routine cleaning or maintenance.
