An item with a cleaning code of "I" indicates what about the cleaning process?

The cleaning code of "I" signifies that a decision must be made regarding the best cleaning method to use that will not cause injury to the item or compromise its integrity. This code emphasizes the importance of considering the specific characteristics of the item, including the materials it's made from and any sensitive components it may have.

In practice, this means that while the cleaning process may involve various cleaning agents or techniques, the focus should be on ensuring that whatever method is chosen does not lead to damage or adverse effects. This consideration is critical in preservation and packing because improper cleaning can lead to deterioration, discoloration, or other damage to the item being worked on.

The other choices present specific limitations or requirements that may not universally apply to all items marked with a cleaning code of "I" and do not capture the flexibility and consideration necessary when dealing with such a cleaning instruction.
