One has several different options on which stain to use to antique a sideboard. These include: Gel Stains, Distress Stains, and Old Masters Wood Stains.
to remove a stain, u need to dissolve it chemically. some stains are simply dissolved with water, but when it comes to fat it's hydrophobic (for example, if you try to mix oil and water they don't mix), that's why u need to use organic solvants or detergents in order to dissolve the stain so you would be able to remove it
