On site rapid detection of surface
cleanliness of catering utensils Instructions for using the cleanliness detection card [ Scope of Application] This method is suitable
for on-site rapid detection of the cleanliness and hygiene status of catering
utensils, food processing utensils, and operating countertops. [ Detection Principle] If dining utensils
and food processing utensils are not cleaned thoroughly, there will often be
protein residues. Protein is a breeding ground for microorganisms and a
component of bacteria. This method utilizes the principle that specific
reagents can react with residual proteins on the surface of an object to
produce color, in order to determine whether the surface of the object is
hygienic and the degree of hygiene. [ Operation Method] 1）Drop
2 drops of wetting agent onto the surface of the tested object. 2）Take
out a piece of testing card, peel off the surface film of the test paper, face
the area where the wetting agent is added, and cross and wipe back and forth
in an area of 10 × 10cm. 3）Place
the wiped test card flat with the test paper facing upwards. 4）Drop
1 drop of developer onto the test paper, and within 3 minutes, compare the
color of the test paper with the reference color card. 5）The
comparison results are divided into clean, slightly unclean, unclean, and
deeply unclean. [ Precautions] 1）Each
detection card is disposable. 2）Do
not touch the testing area of the test strip with your hands. 3）If
there is liquid on the surface of the object to be inspected, wait until the
liquid is slightly dry before conducting the inspection. 4）This
product is valid for 12 months when stored at room temperature. 5）Product configuration: 50 quick test
cards, 1 bottle of wetting agent and 1 bottle of color developer, and 1 color
control card.
