Hello all together...
i am restorating a DEC TU56 dual drive in the moment. My question is,
how to clean the tapes, not the drive.
The tapes i have are found in a garage, where they been for about 25
years without a case. Some ideas how to clean them without damaging?
Best regards
Marco

Quite possibly nothing needs to be done. DECtape was famously strong, enough so that it
had a reputation of being completely indestructible. (Not true; at Lawrence University we
did wear it out, but that?s because it was used as shared public mass storage.)
If it?s horribly dirty, you might wipe the surface with something mild like alcohol and
let it dry.
The reason is that DECtape is a sandwich: the magnetic material is not on the surface as
it is on other tapes.

Try on leader first if you use any solvent. I think I tried alchohol once
and it disolved the magnetic layer.

Definitely good advice for all solvents and all things you?re trying them on.
I?d be surprised if it affected DECtape, but the experiment is clearly a good idea.
