Depends... RP04 (3330) packs, as I recall, have 10 platters plus
protective dummy platters at the top and bottom, so it looks like a 12
platter assembly.

Depending on the age and recording density, cleaning with suitable
solvents (for example, high grade isopropyl alcohol) and Kimwipes
would work just fine.

When I was in college, we had an IBM 1311 that sprang a leak
(hydraulic head actuator...) spraying hydraulic fluid all over the
system pack. The FE repaired the drive, wiped the heads and pack with
solvent, and started things back up. Worked just fine.
