What must you always refer to for cleaning guidelines when dealing with an unfamiliar item?

The ideal reference for cleaning guidelines when faced with an unfamiliar item is the manufacturer's manual. The manufacturer's manual typically provides specific instructions on how to properly clean and maintain the item, taking into account the materials and construction techniques used. Following these guidelines is crucial to ensure that the item is not damaged and remains functional over time.

Manufacturer's manuals often include details about appropriate cleaning agents, recommended methods (e.g., hand-washing versus machine-washing), and any precautions that should be taken to avoid causing harm to the item. Adhering to these specific guidelines from the manufacturer helps to ensure that the integrity and longevity of the item are preserved.

In contrast, risk assessment reports may provide helpful information about potential hazards but do not include detailed cleaning instructions. A 12-digit packaging code typically relates to product identification rather than cleaning guidelines. Company policy documents may offer general cleaning procedures but might not cater to the unique specifications of every item, especially unfamiliar ones. Therefore, turning to the manufacturer's manual ensures that the most accurate and applicable cleaning guidance is followed.
