Allertest™ NI Instructions for Use
Step 1 - Place one drop of solution A on a cotton-tipped applicator (not included). Place one drop of solution B on the same applicator (be sure to use equal amounts of both solutions). Recap both bottles tightly.
Step 2- Rub the wet applicator firmly against the metal object you wish to test. Rub for at least 15 seconds.
Step 3 - If the wet area of the applicator turns a strawberry-red color, the test is positive. A positive test indicates that the metal object contains nickel.
