Well I don't have an RL pack cleaner. And in my case it won't suffice, I 
really need to access the top surface. There are some smudges that need 
more thorough cleaning with some pressure that I can't apply with just 
sticking in a swab or something from the side.

OTOH the top loading disk packs for our Nova 3 (6045 drive) can be 
easily dismantled. I thought that the DEC packs would be similar but no, 
DEC had to invent something different...
