A medical cleaning system is used for cleaning at least a portion of a surgical instrument. The system may include a tray, a heating pack, and a non-abrasive cleaning pouch. The tray may include a basin area used as a reservoir for maintaining, e.g., antifogging fluid, and a sloped ramp to allow liquids to flow down into its basin area. The system may also include a heating pack enclosing a heating pack solution. The heating pack solution may be a solution having nucleating properties. The heating pack solution may be activated by a mechanical activator to generate heat to the antifogging fluid. The generated heat may be transferred to the antifogging fluid residing on the non-abrasive cleaning pouch. The surgical instrument may be cleaned by wiping a portion of the surgical instrument, e.g., a lens, over the non-abrasive cleaning pouch.
