HP recommends cleaning the heads on the 14" drives with a flat wand, and a
cleaning sleeve that fits over it.

Tex-wipe made them
They're called Tex-Sleeves and are a blue plastic split wands that
look like oversided tongue depressors (1" x 6") with a lint free
cloth sleeve that slides over that like a sock.
The ones I have are in storage, will retreive the part numbers for
you.
I have extras of the plastic parts, but am running out of sleeves.
This is exactly the right thing for cleaning 2315/5440 style upper/lower
heads.
