What to do with extra neutral conductors in panel?

I have a few 240V circuits (tankless water heater, sprinkler pumps etc...) but NM 6-3 or 12-3 wires were used so the while neutral conductors in them are useless.

What do you do with this extra neutral conductor?

I have seen someone cut them real short almost flushed with where the wire enters the panel or box, and I have seen some just cap and tuck them out of the way.

Is there a standard way to deal with them?

You possibly have timers associated with the sprinkler or the water heater, so it will need the neutral for that application. If it is a pure 240 volt application and the neutral is not being used on either end, cap them off on both ends and leave them in the box. Future proof.
