The PRO-Clean hygiene swab enables users to accurately monitor the cleanliness of food equipment surfaces to ensure food safety and product quality. The swab quickly detects protein residues left on a surface after cleaning.
To test for cleanliness, users swab a surface and activate the self-contained swab. If food residue is present, the reagent will turn purple.
The colour change provides a semiquantitive measure of surface cleanliness: the more contamination present, the quicker the colour change to purple and the darker the colour.
PRO-clean swabs have an 18-month shelf life and can be stored at room temperature. The company claims the swab is a viable alternative to other protein residue tests.
