While we consider ourselves professional carpet cleaners, on the inside we are actually chemists. Much of what we do on a day-to-day basis relies on the power of hydrogen scale (pH). This is a scale of 0 to 14 showing how acidic a substance is versus how basic it is (meaning, how much alkaline it contains). Acid and alkaline are opposite properties, so the lower the number on the pH scale, the more acidic and the less basic. By way of reference, water is neutral, so it has a pH of 7.0.

Why this is important for cleaning is that there are times when we need to use an acid-based solution (such as for wool carpets and pool decks) and other instances when an alkaline-based solution is required (such as for synthetic carpets and kitchen tiles). Mixing acids and bases can cancel out the effects of one another, similar to how hot and cold water running together results in a lukewarm temperature. More importantly, using the wrong substance can damage the surface.
