Abstract
Cleaning articles including a heat engine incorporated therein. The cleaning article may include a substrate (e.g., a non-woven wipe) including one or more layers. The heat engine may be in the wipe or pad, and includes a reactive metal composition which upon contact with a salt water (e.g., saline) composition, reacts to produce heat. The cleaning article may thus produce water vapor and/or steam upon activation of the heat engine. A venting structure may be provided adjacent to or surrounding the heat engine that includes an impermeable material (e.g., impermeable to water and/or air or other gas), which includes one or more vents through the impermeable material. The venting structure directs water vapor and/or steam to a desired face of the cleaning article, away from the user. A heat barrier layer may insulate a user's hand from the generated heat, and/or a handle may be attachable to the pad.
