ABSTRACT:
Wipes, methods and kits useful for testing and/or removal of metal from surfaces (such as, dermal surfaces) are disclosed. Exemplar wipes, including the combination of a three-dimensionally textured absorbent support, a cationic surfactant, and a weak acid, are disclosed. In some examples, the cationic surfactant is isostearamidopropyl morpholine lactate (ISML), and the weak acid is citric acid.
