When washing tableware in a three-compartment sink under ServSafe guidelines, you must use hot detergent water at a minimum of 110°F (43°C) in the wash compartment.

Basic ServSafe Rule

  • The first sink (wash) must have a detergent solution that is at least 110°F to effectively remove food, grease, and soil from tableware.
  • Water must be changed whenever it becomes dirty or the suds are gone to keep washing effective and sanitary.

ServSafe Three-Compartment Sequence

ServSafe outlines a specific 5-step process when using a three-compartment sink for tableware:

  1. Pre-scrape or soak
    • Rinse, scrape, or soak items before putting them into the wash sink to remove loose food debris.
  1. Wash (1st sink)
    • Wash items in hot water with detergent, at least 110°F.
 * Scrub to remove food, grease, and stains, changing the water when dirty.
  1. Rinse (2nd sink)
    • Rinse items in clean water to remove all soap and food particles so sanitizer can work properly.
  1. Sanitize (3rd sink)
    • Place items in a properly mixed chemical sanitizer or in very hot water, following required time and temperature for that sanitizer or 171°F hot water if using heat sanitizing.
  1. Air-dry
    • Set items on a clean, sanitized surface and allow them to air-dry; do not towel-dry.

Mini “Quick Scoop” Summary

  • Use at least 110°F detergent water in the first compartment when washing tableware in a three-compartment sink (ServSafe standard).
  • Follow the order: scrape → wash → rinse → sanitize → air-dry. Skipping a step can make sanitizing ineffective and increase foodborne illness risk.
