Odd. All 3.5" double-head drive service manuals -- in fact just about all
double-head flopply drive service manuals -- that I've read warn against

I've always used a cotton bud though, and had no problems at alll.
Perhaps I am jsut very careful, but I have never distorted that gimbal
spring during cleaning.

Firstly, clean the heads -- not with a cleaning
disk (no matter what the
manuals may say), but with a cotton bud and propan-2-ol.
Be EXTREMELY careful doing this. At least on 800k Mac floppies it it very
easy to bend the flexure on the upper head so that it no longer has enough
downward pressure to make contact with the disk.
