I have a new Catskill end grain wooden cutting board. I opened it up and oiled it about 4 times over the span of about a week. After letting it dry thoroughly, I started using it. I have only used it two times and after each use I would spray it with white vinegar (full strength, I didn't remember to mix with water 1:1 ratio) My Question: The board has now become quite rough like fine sand paper, I am guessing it has just become dried out and needs more oiling am i correct? or has the acidity marred the surface and I should sand it and re-oil?
