Cleaning your disk drives is actually pretty easy. It just takes some time. Be patient.
If you are trying out some floppy disks that have not been used for quite some time, you might inspect them first before you put them in your drive. If the disk has disk rot, it can gum up your read head and your disk drive won’t read. While a disk cleaner can take care of light work, it won’t take care of cleaning disk rot. You may have to take apart and clean quite a few times if you run through some disk rot floppy disks. If the disk looks pretty bad, I would suggest not putting it in your disk drive at all.
Yes, I know this is the older version. Principal is pretty much the same. I currently use 99.9% Isopropyl Alcohol cleaning my disk drives.
