Steps
Download the current GS-42 standard and guidebook from greenseal.org and confirm you are referencing the latest published edition (Edition 2.3, most recently amended via corrections/clarifications) rather than an older archived edition
Build building-specific green cleaning operating procedures covering chemical/equipment selection, sustainable purchasing, and reduced-impact practices
Establish an employee training program covering safe use of green-certified products and equipment per the standard's training criteria
Implement tenant/occupant communication protocols disclosing the green cleaning program
Submit an application and supporting documentation to Green Seal for evaluation and certification
Track any Green Seal corrections/clarifications reports that may adjust requirements between full edition revisions
Known gotchas
GS-42 has gone through multiple point revisions (e.g., prior editions from 2011 and earlier editions) — always confirm the edition number and any published corrections/clarifications currently in force on greenseal.org before citing requirements to a client
GS-42 governs the cleaning service/program, not individual cleaning products — product-level Green Seal certification (e.g., GS-37) is a separate standard
Verify current certification fees and audit cadence directly with Green Seal, as these are not fixed indefinitely
