I found this great product called cutting board oil and wax at Art Of Turning. This guy is a woodturner and uses it for all his kitchen bowls that he turns.
Anyway, there’s two separate products and I got both. They work great in conjunction with one another.
The first is cutting board oil conditioner. This is a special blend of natural ingredients that works perfectly to restore and keep my quality cutting boards looking great. (find some good ones here on Amazon)
Next is the cutting board wax. The wax works to protect the oil and keep the board from getting stains and funky smells.
I apply it basically once a month, but use my boards quite often. I also used it on my wooden kitchen spoons, honey dippers, and as a wood oil for charcuterie boards and it works great for bringing those back to life, too!
All in all, it’s a fantastic food safe wood finish!
