How to let it live a long life?

I heard people talking about using mineral oil w.r.t the same. How much and when use it?
The care of bamboo cutting boards is extremely similar to that of traditional wood cutting boards:


Prime them with mineral oil, and refresh it every month or so.  (Wipe with oil, let sit for a while, perhaps 15-20 minutes, wipe off).
Wash only with mild soap, and rinse and dry immediately. (Wipe off and let air dry.) Don't put in a dishwasher.
If using for raw meat, you can sanitize with a very dilute bleach solution (about a teaspoon of liquid bleach per quart of water, 5 mL per liter).  Rinse thoroughly afterwards.
