Hygiena PRO-Clean® PRO-100 is a rapid surface protein residue test used to verify cleaning effectiveness on food-contact and non-food-contact surfaces after cleaning.
PRO-Clean uses a simple green-to-purple colour change to indicate whether protein residue remains on a surface. It requires no luminometer, no reader, and no laboratory equipment, making it a practical sanitation verification tool for Canadian food processors, beverage plants, breweries, wineries, dairy facilities, cannabis processors, commercial kitchens, sanitation teams, and QA/QC departments.
| Application | How PRO-Clean Helps |
| Food processing sanitation | Helps verify whether protein residue remains on selected surfaces after cleaning and before production restarts. |
| Allergen-control and changeover cleaning | Supports cleaning verification during product changeovers where protein residue removal is part of the sanitation program. |
| Breweries, wineries, and beverage plants | Useful for checking cleaned tanks, fillers, transfer points, packaging equipment, tools, and other defined sanitation locations. |
| Dairy and ready-to-eat production | Provides a simple visual residue check for facilities where protein residue and sanitation documentation are important. |
| Cannabis and controlled production | Can support cleaning verification on benches, tools, production rooms, and shared-contact surfaces where residue control matters. |
| Commercial kitchens and sanitation teams | Gives staff a simple pass/caution/fail-style visual check without requiring electronic equipment. |

| 10 minutes | 20 µg | Higher-sensitivity residue verification before final pass/fail interpretation. |
Disregard colour changes that occur after 10 minutes and follow the Hygiena instructions and your internal SOP for result interpretation.
PRO-Clean is a visual protein residue test. It is useful when your goal is to check whether protein residue remains on a cleaned surface, especially in food processing, changeover cleaning, and allergen-control support programs.
ATP swabs, such as Hygiena UltraSnap Surface ATP Test Swabs, are used with a compatible luminometer to measure ATP as a rapid hygiene indicator. ATP testing provides numeric results and trendable data, while PRO-Clean provides a simple visual colour-change result without instrumentation.
PRO-Clean detects protein residue. It can support allergen-control and product changeover cleaning programs, but it does not identify a specific allergen and does not replace allergen-specific testing where that testing is required by your SOP, customer requirement, audit program, or regulatory expectation.
PRO-Clean is intended for use on surfaces after cleaning. For best results, test surfaces after detergent cleaning and rinsing, and before terminal disinfection when your procedure allows.
Allow PRO-Clean devices to equilibrate to room temperature before use. Swab the selected test area according to your facility procedure, activate the device using the Snap-Valveâ„¢ mechanism, mix according to the instructions, and read the colour result at the appropriate time.
PRO-Clean is designed to detect invisible or trace residue. Do not overload the swab with visible soil or heavy physical matter, as this can interfere with the reaction and produce inaccurate results.
PRO-Clean provides rapid protein residue screening data. It does not replace ATP testing, microbiological testing, allergen-specific testing, pathogen testing, regulatory testing, or facility-specific verification methods where those are required.
Cambridge Environmental Products supplies Hygiena PRO-Clean PRO-100 protein residue test swabs in Canada with CAD pricing, Canadian purchasing support, and access to related Hygiena ATP luminometers, UltraSnap surface ATP swabs, AquaSnap water ATP tests, allergen-control tools, and sanitation monitoring consumables.
PRO-Clean is used to check cleaned surfaces for protein residue. It helps sanitation and QA/QC teams verify whether additional cleaning or corrective action may be required.
No. PRO-Clean is a visual colour-change test and does not require a luminometer, reader, or laboratory instrument.
Results are interpreted between 1 and 10 minutes depending on the sensitivity level required. Hygiena lists sensitivity of 80 µg protein at 1 minute, 50 µg at 5 minutes, and 20 µg at 10 minutes.
A purple colour change indicates that protein residue is present. The quicker and darker the colour change, the more residue is indicated.
Yes, PRO-Clean can support allergen-control and product changeover cleaning programs by checking for protein residue on cleaned surfaces. It does not identify a specific allergen and should not replace allergen-specific testing where required.
No. PRO-Clean is a visual protein residue test. ATP swabs, such as UltraSnap, are read with a compatible luminometer and provide numeric ATP results for hygiene monitoring and trending.
Yes. Breweries, wineries, beverage plants, and dairy facilities can use PRO-Clean for surface protein residue checks on selected cleaned equipment, tools, tanks, packaging areas, and production surfaces.
Store PRO-Clean according to the product instructions. The listed storage range is 2°C to 25°C, with an 18-month shelf life at room or refrigerated temperatures when stored properly.
No. PRO-Clean provides rapid protein residue screening data, but it does not replace required microbiological testing, pathogen testing, allergen-specific testing, regulatory testing, or facility-specific verification methods.
