Is there a way to remove old files without relying on internet time service?
Since you don't have Internet NTP, the file timestamps are meaningless, being reset to the Pi's "/etc/fake-hwclock.data" time whenever the system is booted.

Alternatively, use DiskInternals' Freeware Linux Reader for Windows (as I was unable to figure out how to mount .img files with Paragon's ExtFS for Windows).

Detect an SD card that became read-only
You could do a simple write/read test with a test pattern. A good test pattern is a byte with binary '01010101' = 0x55 hex and a byte '10101010' = 0xaa. Writing both will toggle every bit.
