Scrubbing with a brush, using an ultrasonic unit, and using a solvent are all examples of which category?

• A. Methods of cleaning
• B. Steps of decontamination
• C. Types of sterilization
• D. Uses of sanitizers

Answer: (A)

Cleaning is the first line of defense in salon sanitation, and these actions are all techniques used to remove debris and residues from tools and surfaces. Scrubbing with a brush physically dislodges dirt; an ultrasonic unit uses high-frequency sound waves in a cleaning solution to loosen debris from tiny crevices and intricate parts; a solvent chemically dissolves or lifts oils and residues. By removing this material, these methods prepare items for sanitizing or disinfecting, helping sanitizers work more effectively. They aren’t sterilization methods, which aim to kill all microbial life, nor are they uses of sanitizers themselves, which are products applied after cleaning to reduce microbial load.
