Quick answer: this free printable log records sanitizer ppm and water temperature at the three-compartment sink and wiping-cloth buckets, and the final rinse temperature of a high-temperature dish machine. Test every new batch and again during the shift. Chlorine is commonly 50 to 99 ppm at 75°F or above, and quat follows its label at 75°F or above.
Sanitizer is invisible: a bucket mixed too weak looks exactly like one mixed right, and a dish machine that stops reaching temperature still comes out shiny. The only way to know is to test it, and the only way to show you tested it is to write it down. This log covers the three-compartment sink, wiping-cloth buckets, and the dish machine, with the FDA concentration and temperature ranges printed at the bottom of the sheet.
Cleaning and Sanitizer Log
| Date | Time | Where (sink, bucket, dish machine) | Sanitizer type | Strength (ppm) or rinse °F | Water °F | In range? Y/N | If out of range: what you did | Initials |
|---|---|---|---|---|---|---|---|---|
Chlorine: 50–99 ppm in water at 75°F+ (pH 8 or less) or 100°F+ (pH up to 10), or 100 ppm at 55°F+; at least 10 seconds contact. Quat: the strength on the label, water 75°F+, at least 30 seconds or the label time. Iodine: 12.5–25 ppm, 68°F+, pH 5 or less, 30 seconds.
Hot water: manual sinks 171°F+ for 30 seconds; dish machine final rinse 180°F (165°F for stationary-rack, single-temperature machines), never above 194°F. If out of range: remix or reheat, retest, and rewash anything sanitized since the last good test.

How to Fill It In
- Write the product and its label strength at the top, such as "quat tablets, 200–400 ppm." The label, not habit, sets the range for quat and other sanitizers.
- Test every time you mix a new batch, and again during the shift. Sanitizer weakens as it picks up food soil, and chlorine gasses off, so a bucket that tested right at 7 a.m. may not be right at noon.
- Use the strip that matches your sanitizer. Chlorine strips don't read quat, and quat strips don't read chlorine. Dip for the time on the strip's label and compare the color right away.
- Write the water temperature too. Every chemical sanitizer has a minimum, and a sink filled from a tap that's run cold can fail on temperature alone.
- For a high-temperature dish machine, log the final rinse temperature from the gauge. Check the data plate for your machine's numbers, and run a heat-sensitive test label through now and then to confirm dishes reach 160°F at the surface.
The Rules Behind the Ranges
| Sanitizer | Strength | Water temperature | Contact time |
|---|---|---|---|
| Chlorine (bleach) | 25–49 ppm | 120°F or above | 10 seconds |
| Chlorine (bleach) | 50–99 ppm | 75°F or above at pH 8 or less; 100°F or above at pH up to 10 | 7 seconds at 50 ppm under those conditions; otherwise 10 seconds |
| Chlorine (bleach) | 100 ppm | 55°F or above | 10 seconds |
| Quaternary ammonium (quat) | As the label directs | 75°F or above; water hardness 500 ppm or less, or as the label allows | 30 seconds, or the label time |
| Iodine | 12.5–25 ppm, pH 5.0 or less | 68°F or above | 30 seconds |
| Hot water, manual | Not applicable | 171°F or above | 30 seconds, immersed |
| Hot water, dish machine | Not applicable | Final rinse 180°F (165°F for stationary-rack, single-temperature machines), at most 194°F | Dish surface reaches 160°F |
These come from Food Code §4-501.111, §4-501.112, §4-501.114, and §4-703.11. Every chemical sanitizer also has to be used as its EPA-registered label directs, so if your label gives a different strength or contact time, follow the label.
Three more rules make the log matter:
- A test kit is required. Every kitchen that sanitizes with chemicals needs a test kit or device that measures concentration in ppm (§4-302.14), and concentration has to be determined with it (§4-501.116).
- The person in charge has to monitor sanitizing: concentration, pH, temperature, and contact time for chemicals, and water temperature and time for hot water (§2-103.11(L)).
- Wiping cloths for counters and equipment are held in sanitizer at these same strengths between uses, and the solution has to be free of food debris and visible soil (§3-304.14).
How Often to Clean Food-Contact Surfaces
Sanitizer strength is half the job; the other half is cleaning often enough. Equipment and utensils used with TCS food have to be cleaned at least every 4 hours (§4-602.11(C)), and every time you switch from raw meat to ready-to-eat food, from one raw animal food to another, or when contamination may have happened. In a refrigerated prep room, the interval can be longer if you document the room temperature: 24 hours at 41°F or below, 20 hours at up to 45°F, 16 hours at up to 50°F, and 10 hours at up to 55°F (§4-602.11(D)). If you use that table, this log is a good place to record the room temperature. For everything else in the kitchen, from grills to floor drains, see our kitchen cleaning schedule.
What to Do When a Test Fails
- Too weak: add sanitizer or dump and remix, then retest before using it.
- Too strong: dilute with water and retest. Using more than the label allows breaks the label directions the Food Code requires you to follow, and can leave residue on food-contact surfaces.
- Water too cold: refill from the hot tap and retest.
- Dish machine rinse too cool: stop using it for sanitizing, switch to the three-compartment sink, and call for service.
- Then rewash anything sanitized since the last good reading, and write it down.
Test Strips and Sanitizer
Chlorine and quat strips in one kit. Pros: covers kitchens that use both, such as quat at the sink and bleach in a wiping bucket. Cons: you pay for strips you may not use if you're on one sanitizer. Best for: kitchens with mixed sanitizers, or anyone not sure which one they'll use.
Pre-measured quat tablets: one tablet per gallon of water, with test strips in the pack. Pros: takes the guesswork out of mixing, which is where most failed tests come from. Cons: you still need to test, especially after the solution has been in use. Best for: sanitizer buckets and small three-compartment sinks.
For single-sanitizer strips and more options, see our sanitizer test strips and food-safe sanitizers guides.

Frequently Asked Questions
What ppm should sanitizer be in a restaurant?
For chlorine, 50 to 99 ppm in water at 75°F or above is the common setup, or 100 ppm in water as cool as 55°F. For quat, the strength on the product's label, often 200 to 400 ppm. For iodine, 12.5 to 25 ppm.
How often should sanitizer be tested?
Every time you mix a new batch, and again during the shift, because solutions weaken as they're used. The Food Code requires the person in charge to monitor concentration routinely but doesn't set a number; many kitchens test every 2 to 4 hours.
What temperature should the sanitizing sink be?
It depends on the sanitizer: at least 75°F for quat and for chlorine at 50 to 99 ppm (if the pH is 8 or less), 68°F for iodine, and 171°F if you sanitize with hot water alone.
Is a test kit required?
Yes. The Food Code requires a test kit or device that accurately measures sanitizer concentration in ppm wherever chemical sanitizer is used (§4-302.14).
What temperature should a dish machine's final rinse be?
For high-temperature machines, at least 180°F as it enters the rinse manifold (165°F for stationary-rack, single-temperature machines), and no more than 194°F. Your machine's data plate lists its exact numbers. Low-temperature machines sanitize with chemicals instead; log their ppm.
Bottom Line
Test every new batch, write down the ppm and the water temperature, and fix anything out of range before the next dish goes in. If you're training staff on the sink setup, our cleaning and sanitizing quiz covers the same numbers.
