Scrubbing, Baking and Boiling

I've seen on here where people harvest their own chin safe wood and boil, scrub and bake it, to make it chin safe. What do you use to scrub it? how long should you boil it and how long do you bake it for?

I have some people around me that have pecan trees and I was wanting to make some toys out of the pruned branches for my chin, along with some other wild fruit trees we have around. Also, I know that fruit trees that bear fruit with pits in them ( peaches, etc ) are poisonous to chins...
