I just caught this on the tube, for periodic cutting board cleaning:

Make a paste of dry cleanser (such as Comet), and water. Spread it evenly
over the cutting surface and allow to dry overnight. Next day, rinse
thoroughly under warm water using a paper towel to rub off any excess
cleanser.

Sprinkle wet cutting board liberally with Kosher salt. Scour salt on the
board with a half lemon until salt is dissolved. Give a final quick rinse
under warm water and let dry.

This is said to sanitize and remove stains.

Since I use polypropylene and nylon cutting boards, I'll just keep this for
reference.
