Your Cleaning Station requires no regular mechanical maintenance other than cleaning.
As needed, vacuum your Cleaning Station inside and out. Remove the metal grate and vacuum any residual powder. Wipe the station as needed with a slightly dampened cloth (use distilled water) to remove dust and other debris.
Allow the station to dry completely before using again.
Caution: Do not use fluid to clean the grate - if the vacuum is running, the water might be sucked into the collected powder causing it to begin the process of hardening.
