PRO-Clean Protein Residue Tests are $74.95 for 25 tests.
PRO-Clean is the easiest and most accurate way to verify the cleanliness of food equipment surfaces. Simply swab a surface and release the reagent. If protein residue is present, the reagent will turn purple – the more contamination, the quicker the color changes and the darker it becomes. PRO-Clean instantly validates surface hygiene, allowing immediate corrective action to be taken when necessary.
