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 oxygen, reacts to produce heat. The cleaning article may thus heat water or a cleaning composition, and may produce water vapor and/or steam upon activation of the heat engine. A venting structure may be adjacent to the heat engine, and may include one or more vents through the impermeable material. The venting structure may allow air to access the reactive metal composition, and/or may direct 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.
