Why is it important to check the type of contaminant for cleaning items?

Understanding the importance of identifying the type of contaminant for cleaning items is crucial, primarily to ensure that the cleaning process does not cause damage to the item itself. Different materials and contaminants require specific cleaning methods and agents. For instance, using a harsh chemical cleaner on a delicate surface could lead to irreversible damage, such as discoloration, scratching, or structural compromise.

By knowing the type of contaminant present, one can choose an appropriate cleaning solution that effectively removes the contaminants while being safe for the material of the item. This careful consideration prevents the potential for damage that might otherwise result from improper cleaning methods. Ultimately, the goal is to maintain the integrity of the item being cleaned while achieving the desired cleanliness.
