Because you generally use a cleanser that has an opposing pH value to the stain or dirt. This opposition in pH is to target a neutralization of the overall pH value once cleaning begins.
ALKALINE STAIN If you have an alkaline based stain, you would opt for an acidic based cleanser (ie. hard water stains, generally an alkali, can usually be addressed with a hydrogen peroxide based cleanser which is acidic).
ACIDIC STAIN If you have an acidic stain or dirt (ie. dead skin, soda, food, etc.) you would explore an alkaline based cleanser like bleach, ammonia or alcohol....in diluted mixtures with soap. (But never ever, mix bleach with ammonia.)
