One problem with MO is that it never dries or cures.  On cutting boards, it either soaks in deeper or gets washed off the surface with the detergents.

lazy- i guess i should try it because the mineral oil just doesn't last very long the way mu=y wife cleans. im talking wiping down the boards 3 times with 409. 

Hmm, 409 would not be first choice for wood.  Might need to mix up something a little gentler for wood.  If nothing else, I think that I would dilute the 409.  I've always read that you should use vinegar to clean butcher blocks but I've never tried it.  I think that one I saw added a few drops of dish soap to white vinegar and sprayed that on to help remove grease.    

I just read the ingredients of 409.  I am surprised you can buy that in California.  😀
