RK05' s are fairly easy to clean. I cleaned a couple of 'em for my 11/23
with some texwipes and 97% isopropyl alcohol.
DEC used to have techsleeves that went over the top of a plastic applicator
and I also used them when saturated with alcohol -- to clean the RK05 packs.
Never had a problem on my packs... also did the RK05F pack.

Disassembling any pack I saw most usually resulted in a destroyed

such :-)
anyway, I bought a pack inspector which has a number of spindles, which

the cover, and allow the pack to be moved manually with precision, and
it also has
two mirror units which will allow you to view the surface w/o any
disassembly.
There is no motor, only manual moving of the pack, but they did have a
catch which
allows you to have a reference when you pass the same place in the
rotation, other than
that it free spins. There is also a light source, and another
attachment that allows you to
mount a micrometer with a feeler to check for out of round, or bent
platters.
when I had a pack cleaned, they used this sort of unit in a clean room
to clean and
certify the pack (in the early 80's time frame).

[...] Cleaning a pack takes about 20
minutes (including disassembly and reassembly) so don't expect these to
be done quickly.
