Washington requires grease traps to be cleaned at minimum Every 90 days. However, high-volume restaurants in Spokane may need more frequent service. The industry standard 25% rule applies: schedule a cleaning before fats, oils, and grease (FOG) reach 25% of your trap's capacity. Regular maintenance prevents costly backups, foul odors, and health code violations.

In Washington, grease trap maintenance is regulated by WA Dept of Ecology / Local utility. Commercial kitchens must clean traps at least Every 90 days. A licensed hauler must transport the waste and provide a signed manifest. Businesses must retain cleaning records for at least 3 years.
