Most soils are acidic, averaging between 4 and 5. Soils will be easier to remove when they are neutral. When alkaline mixes with fats, oils, and grease, they form a soap.
What is the pH of a carpet cleaner?
At this time the IICUC, along with fiber producers and carpet mills, made guidelines for cleaners. The scholars argued for comprehensive recommendations, but the majority wanted a simple regulation. This led to the pH 10.0 rule, which states that most fiber should be cleaned with solutions of pH 10.0 or less, but the rule is flawed since it does not consider the roles of buffering and reactivity. Some detergents with a pH of 9 are too alkaline; while others as high as pH 11 are not a problem.
Why is pH important in carpet cleaning?
As carpet cleaners, we know pH is important. The acidity or alkalinity of a cleaning solution will impact its safety and efficacy for different types of fibers, dyes, and soils. Yet many technicians are taught “one size fits all” guidelines regarding carpet cleaning and pH when the truth is actually much more complex.
