Best way to remove ltm M adapter from lens

[raid]

I used an old Leica M lens rear cover, and I unscrewed the adapter easily. No WD40 or WD50 was used.

Glad it's solved. I've always used the same trick with a rear cap.

I will try the alcohol treatment for the lens mount.

alcohol loosens everything...and, everybody

With the Voigtlander cap, mount the lens on the camera body, unscrew the lens from the adapter, use the notches on the back of the cap to remove the mount from the camera body.
Or try the alcohol method, have a drink and worry about it tomorrow

This worked for me too.I always carry the cap in my bag.
