Washing hands with soap and water is the most effective method for sanitizing hands before a client service. This process involves lathering with soap, which helps to remove dirt, grease, and microorganisms from the skin's surface. The friction created while scrubbing is vital as it dislodges pathogens from the skin. Following this, rinsing under running water washes away the soap along with the contaminants.

Using just an alcohol-based hand sanitizer, while beneficial, is not as effective as washing with soap and water, particularly if the hands are visibly soiled or greasy. Hand sanitizers can be convenient in many situations, but they do not eliminate all types of germs and may not be as effective when hands are dirty.

Rinsing hands under water alone does not adequately clean the hands, as it only removes some surface dirt but fails to address germs effectively. Wiping hands with a towel does not sanitize them, as it does not remove bacteria or viruses; in fact, it could potentially spread contaminants if the towel is not clean.

Thus, washing hands with soap and water is the standard practice recommended to ensure proper sanitation before engaging in client services in a barbering context, making it the correct choice.
