Hey! I was thinking:
Here in Brazil, we use both steel wool and some woods oil to dark woods fingerboard and Lemon oil to maple fingerboard...
My doubt:
Does the Lemon Oil would help in stop the "darkening" of rosewood/ziricote fingerboards? And it would not damage the fingerboard right??
Thank you!
EDIT: The rosewood I've just bought was cutted before 1992 and was drying, so, perhaps some oil would be good, do you agree?
