What type of pH value is indicated by a reading greater than 7?

A pH value greater than 7 indicates an alkaline condition. The pH scale ranges from 0 to 14, where values below 7 represent acidity, a value of 7 is considered neutral, and values above 7 classify as alkaline (or basic). This classification is critical in carpet cleaning and maintenance because many cleaning agents, particularly those that are effective in removing stains and residues, are designed to function optimally at specific pH levels.

Understanding that a pH above 7 is alkaline is essential when selecting the appropriate cleaning products for different types of carpets or stains. Alkaline cleaners are often used for greasy or oily stains because they can break down the bonds that hold those types of dirt in the carpet fibers.
