How do I clean the fabric softener dispenser in kenmore model 22102. The manual says it is not removal

To remove residue from the dispensers, wipe them with a damp cloth and towel
dry. Do not attempt to remove the dispensers or trim for cleaning. The dispensers and trim are not removable, if your model has a dispenser drawer, however, remove the drawer and clean it before or after you run the Clean Washer cycle. Use an all-purpose surface cleaner, if needed.
