That's an excessive amount of work for a process that sometimes needs to be performed several times a week. Yes, I have thousands of old floppies and the constant use of them requires continuous maintenance on the drives I use them in. I guess for the casual hobbyist disassembly is not a problem but I just can't afford all that time and labor over and over again.
I've been using the cleaning disks for over 25 years without any problems and don't know that I would have been able to remain focused if I needed to disassemble, clean, reassemble and check these drives on a regular basis. I don't think I would have time to do the work I had at hand if it were not for the time-saving efficiency of these cleaning disks.
If you need to clean your drive that often you be running disks through it almost 24hrs a day
As a casual user of 5.25" disks I only need to clean my drives once a year (if that) so it's no big deal for me. I also have a strict rule that if the disk is at all flaky or dirty it goes in the bin; no exceptions.
