A well-kept grease trap cleaning log tracks service dates, grease levels, and any issues found during each cleanout, giving you a clear maintenance history that health inspectors and local regulators expect to see. For restaurants, cafeterias, and commercial kitchens in the Pacific Northwest, that record starts the moment you schedule grease trap cleaning in Auburn, WA. Keeping it updated from there is what turns a single service visit into a documented, compliant maintenance system.
What Goes Into a Grease Trap Cleaning Log
Think of your log as a maintenance journal. Every entry should capture the same core details so records stay consistent over time. Here’s what each entry needs to include:
- Date of service
- Name of the service provider
- Grease and solids levels before and after cleaning
- Volume of waste removed
- Any damage or abnormalities observed
- Next recommended service date
King County and many Washington municipalities require food establishments to maintain these records for at least three years. The King County Local Hazardous Waste Management Program recommends quarterly cleaning for most commercial kitchens, though high-volume operations may need service more frequently.
Why Consistency in Logging Pays Off
Skipping entries or keeping vague notes creates gaps that can come back to bite you during an inspection. Regulators want specifics, and a spotty log raises red flags even when your trap is physically clean.
Consistent records also help you spot patterns. If your grease levels are rising faster between service visits, that’s a sign your kitchen output has increased or something upstream has changed. Catching this early through your log gives you time to adjust your grease trap service schedule before a backup or overflow occurs.
Paper vs. Digital Logs
Both work, but digital logs stored in a spreadsheet or cloud-based system are easier to organize, search, and share with inspectors on request. If you go paper, keep the binder in a fixed, accessible location and make sure multiple staff members know where it is.
Whichever format you choose, designate one person to be responsible for updating the log immediately after each service visit, not days later when details get fuzzy.
How Often Should You Schedule Service?
The 25% rule is the most widely cited standard: schedule cleaning when the combined depth of grease and solids reaches 25% of the trap’s total liquid depth. For many commercial kitchens, grease tank cleaning falls somewhere between every one to three months. High-output kitchens may need monthly visits.
Your service provider should give you a written report after each visit. That report becomes your log entry.
Questions We Hear All the Time
What happens if I can’t produce my cleaning log during an inspection?
Most health departments will issue a violation even if your trap itself is clean. The log is proof of ongoing compliance, not just a formality.
Can I keep the log myself between professional visits?
Yes. You can log visual checks, odor changes, or slow drainage, but professional service records from a licensed provider are what regulators require for official documentation.
Does the log need to be signed by the service technician?
In many jurisdictions including King County, yes. Always ask your technician to sign and date the service report so your records hold up officially.
