Abstract
This disclosure describes example antiseptic applicators that may be used in combination with one or more cleansing, antimicrobial and/or antiseptic agents to reduce or eliminate contaminates on a surface. According to some embodiments, the disclosure describes that the applicators may contain an impermeable layer and a permeable layer, where the impermeable layer prevents contaminates for transferring from a user's hand to the permeable layer and the surface.
