Doing some research they do say fretboard may have slight oil finish and can use tiny amount and wipe immediatelyI wouldn't since it is Maple and is not same finish as back of neck on my Special with Roasted Maple just use EBMM fretboard cleaner
Had bass little over 2 years and back of neck still like the day I got it
See no need for Wax/Oil at this time
