Study Notes
Cleaning and Sanitizing Overview
- Cleaning involves removing food and dirt from surfaces.
- Sanitizing reduces pathogens on surfaces to safe levels.
Types of Cleaners
- Must be stable, noncorrosive, and safe.
- Categories include detergents, degreasers, delimers, and abrasive cleaners.
Cleaner Guidelines
- Follow manufacturer instructions precisely for safety and effectiveness.
- Use cleaners only for their intended purposes; avoid substituting different types.
Sanitizers
- Must sanitize food contact surfaces after cleaning and rinsing.
- Sanitizing can be done using heat or chemical methods.
Heat Sanitizing
- Soaking in water at 171°F for 30 seconds is one method.
- High-temperature dishwashers can also be used for sanitizing.
Chemical Sanitizing
- Includes soaking or spraying tableware and utensils in a sanitizer solution.
- Common chemical sanitizers include chlorine, iodine, and quaternary ammonium compounds (quats).
- Regulated by state and federal environmental protection agencies.
Factors Influencing Sanitizer Effectiveness
- Key factors: concentration, temperature, contact time, water hardness, and pH.
Concentration
- A mix of chemical sanitizer and water is critical; measured in parts per million (ppm).
- Testing kits are used to check concentration.
- Hard water and contaminants can reduce sanitizer effectiveness.
Temperature
- Sanitizing solutions must maintain proper water temperature for effectiveness.
Contact Time
- Defined as the time a disinfectant requires for the desired microbial effect, per the manufacturer's instructions.
Water Hardness
- Refers to the mineral content in water, which can impact sanitizer effectiveness.
pH
- The acidity or basicity of a solution can influence sanitizer efficiency.
Chlorine Specifics
- Water temperature for effective chlorine sanitation must exceed 100°F (38°C).
- Maintain chlorine solutions within specified pH levels for optimal performance.
When to Clean and Sanitize
- Surfaces that touch food must be cleaned, sanitized, and rinsed to prevent dirt accumulation.
- Important times include after use, before switching food types, after interruptions, and after four hours of continuous use.
Cleaning and Sanitizing Surfaces: Guidelines
- Start by removing food from the surface.
- Wash with an approved cleaner followed by rinsing.
- Sanitize with a properly prepared sanitizing solution.
- Allow surfaces to air dry.
Cleaning and Sanitizing Equipment
- Unplug equipment before cleaning.
- Remove and clean removable parts by hand or in a dishwasher if permissible.
- Wash, rinse, and sanitize all surfaces to ensure thorough cleanliness.
- Ensure air drying to avoid contamination.
