Rub the bat along a iron fence post at the "ball park". Do not use a painted post, the paint will rub into the bat.
If you have a glass coke bottle, place the bat on the floor and rub. Develops wrists and forearms [2 for 1 motion].

The ML players receive the top grade [seasoned longer]. minor league the next grade and retail store the lowest grade.
