Directions: Apply 2-3 drops of Nickel Alert to a cotton swab. Rub any metal item with swab for 15-30 seconds. Any pink-red color on the swab indicates nickel is detected. If the item you are testing has been recently cleaned, set aside for 24 hours before testing. This will allow for a more accurate test. Nickel Alert will show a positive result even for minute traces of nickel. To demonstrate a positive result, test a US nickel, dime or quarter, which will turn your swab pink.
