Make a cleaning plan for each part
Read separate instructions for the sleeve, motor, caps and charging contacts.
Make a parts list from the instructions
Check which pieces come apart without tools and which stay assembled. A detachable cap, removable motor and removable sleeve are three different features. If the instructions describe one piece as washable, look for separate directions for the rest.
Read the water limits for the exact assembly
A product page may say waterproof without stating which parts the rating covers or what must be closed. Read the manufacturer’s directions before rinsing or immersing anything. Follow their directions for letting components dry before reassembly or charging.
Check the actual storage footprint
Overall dimensions help you check drawer or case space. Insertable dimensions describe the sleeve interior. If the caps need to stay separate while pieces dry, allow room for those parts as well. Keep the model name and charging cable together when you store it.
