GS-42

COMMERCIAL AND INSTITUTIONAL CLEANING SERVICES

The Green Seal Standard for Commercial and Institutional Cleaning Services, GS-42, establishes requirements for cleaning service providers of commercial, public, and institutional buildings, including in-house and external cleaning services, to ensure a quality operation carried out by a highly trained workforce skilled in effective green cleaning practices. Custodial teams meet requirements for building-specific operating procedures, sustainable purchasing, employee training, and tenant communications to ensure a safer, cleaner, healthier building for custodial teams and building occupants.
