Finishing a cutting board?

[Brian Kent]

I just made my first end-grain cutting board from leftover walnut strips. I did some searches and saw that most people recommend mineral oil. So I went over to Ralphs and got some mineral oil from the "lubricant laxitive" aisle. The directions tell me how to use it as a laxitive, but I need help with working it in to the cutting board.

I soaked in the first coat. Do I keep going immediately or let it cure for hours or days?

It was really an interesting discussion with the teenage clerk who wanted to know why you can use the same oil for facial care, woodworking, and lubricant laxitives!
