Purpose
Document sanitizer concentration (PPM) every shift so food-contact surfaces and warewashing meet health code requirements.
Complete this sanitizer concentration log at opening and whenever buckets are remixed during service. Record the chemical type, test-strip PPM for prep and line buckets, verify the three-compartment sink sanitizer, and confirm the dish machine sanitizer is dosing correctly before manager sign-off.
Chemical Setup
Confirm product, strips, and labels before testing.
-
Sanitizer type and target PPM noted (e.g. quat 200-400)
Note
Why it matters: Wrong strips on the wrong chemistry give a false pass. Inspectors ask which product you use before they trust the numbers.
Inspection: Keep the chemical SDS and label range available when the inspector asks for sanitizer documentation.
Common mistakes: Writing 'sanitizer' without naming chlorine vs quat-strips are not interchangeable.
-
Matching test strips available and not expired
Pass / Fail
Why it matters: Expired strips fade and under-read concentration, so you leave food-contact surfaces under-sanitized.
Inspection: Inspectors check strip bottle expiration dates during cleaning and warewashing reviews.
Common mistakes: Sharing one strip bottle across chlorine and quat stations.
-
Bucket and sink labels match the chemical in use
Pass / Fail
Why it matters: Mislabeled buckets cause cooks to mix products or use detergent as sanitizer.
Inspection: Secondary containers must be labeled with the common name of the chemical.
Common mistakes: Leaving yesterday's quat label on a chlorine bucket.
Wiping Bucket Checks
Record PPM for prep and cook-line sanitizer buckets.
-
Prep area sanitizer bucket (PPM)
Range: 0-1000 PPM
Why it matters: Prep tables see raw protein and ready-to-eat food. Weak sanitizer does not kill pathogens between tasks.
Inspection: Inspectors often dip a strip in the prep bucket during the walk-through.
Common mistakes: Testing immediately after adding concentrate before it mixes-wait and swirl first.
-
Cook line sanitizer bucket (PPM)
Range: 0-1000 PPM
Why it matters: Line buckets get the most wiping-cloth traffic and drop below target fastest during rush.
Inspection: A mid-shift line check shows whether the crew remakes solution under pressure.
Common mistakes: Topping off dirty water instead of dumping and remaking to target PPM.
-
Corrective action if bucket PPM out of range (optional)
Note
Why it matters: Documenting remake and retest proves active managerial control when a reading fails.
Inspection: Empty corrective fields next to out-of-range numbers are a common citation.
Common mistakes: Writing 'OK' without a new PPM after remaking the bucket.
Warewashing Checks
Verify sink and machine sanitizer for clean ware.
-
Three-compartment sink sanitizer (PPM)
Range: 0-1000 PPM
Why it matters: Pots and pans that skip the machine still need a verified sanitizer step before air-drying.
Inspection: Inspectors check the sanitize bay with strips even when the dish machine is running.
Common mistakes: Using the wash bay detergent concentration as if it were sanitizer.
-
Dish machine sanitizer dosing verified (chemical or high-temp)
Pass / Fail
Why it matters: A machine that looks clean can still leave bacteria if sanitizer or final rinse heat fails.
Inspection: For chemical machines, confirm sanitizer feed; for high-temp, confirm final rinse temperature per manufacturer.
Common mistakes: Assuming the dispenser is fine because the wash gauge looks normal.
-
Corrective action if warewashing sanitizer fails (optional)
Note
Why it matters: Stopped warewashing or sink fallback must be written down so the next shift knows what happened.
Inspection: Inspectors want time, action taken, and retest-not just a verbal 'we fixed it.'
Common mistakes: Continuing to run racks after a failed sanitizer check.
Manager Sign-Off
Kitchen manager confirms readings are complete.
-
Manager signature / initials

Frequently asked questions
What sanitizer PPM should restaurants use?
Follow the chemical label and your local health code. Chlorine sanitizers for food-contact surfaces are commonly 50-100 PPM; quaternary ammonium (quat) products are often 200-400 PPM. Always use the range printed on your sanitizer bottle and test strips matched to that chemistry-never guess from memory.
How often should sanitizer buckets be tested?
Test at opening when buckets are mixed, then again whenever solution is remade or looks cloudy. High-volume lines often recheck midday because wiping cloths and food soil lower concentration. Log the PPM reading, not just a checkmark, so inspectors can see active managerial control.
What if the PPM reading is out of range?
Remake the solution to the label target, retest with a fresh strip, and write the corrective action on the log with the time. Discard wiping cloths that sat in weak solution. If the dish machine sanitizer fails, stop warewashing until the dispenser is fixed or switch to a verified three-compartment sink procedure.
Do I need different logs for chlorine and quat?
One log works if you note the chemical type at the top of each sheet and use matching test strips. Do not mix chemistries in the same bucket. Customize the note field in SOP Chef with your brand name and target PPM so every shift records the same product.
Who signs the sanitizer concentration log?
The cook or dishwasher who runs the test strips initials each reading. The kitchen manager or shift lead signs off at the end of the check so the sheet is ready for health inspectors reviewing the last two weeks of logs.
