What is the first step to clean and dry a DPM post?

To effectively clean and dry a DPM post, the first step involves wiping down the outside surface. This action is essential as it helps remove any visible dirt, dust, or contaminants that may have accumulated on the exterior. By starting with a thorough wipe, you ensure that subsequently applied cleaning methods or solutions can work more effectively on a clean surface, preventing the re-depositing of dirt and ensuring better overall hygiene and effectiveness of the cleaning process.

Other options, like removing attachments, while necessary in later stages, are not prioritized at this first step of the cleaning process. Submerging the device in water or using a heat source can also cause damage or may not be appropriate for initial cleaning, as they could lead to residues or functional impairments if not handled correctly. Thus, focusing on the initial wipe down is the correct and crucial starting point for cleaning and drying a DPM post.
