Number One Son is a good kid with a bad problem. He's renovating a
bathroom and building a new closet, for which he purchased a prehung
pine six panel door from the Borg. He has stained the door, one coat,
with Minwax red oak and is dissatisfied with the color. Too
dark. Short of ripping out the door and starting over, any
suggestions? Minwax makes a "stain remover" ... anybody have any luck
with that product?

You can sand the wood. This will lighten the color (by removing wood
and stain). However, you can only do this for large flat areas. Cracks
are a pain in the crack.
