What he said. If it is a water based analine then use a water soaked
rag or sponge and try to "wash out" the problems. If it is an alcohol
based analine, then do the same with alcohol. Get it real wet, let it
soak for a bit and scrub like hell.

Analine's are not something to start with. They are hard to use and
Maple is a bitch.

One idea is to sand the heck out of it. Even though you'll have dark
parts in any crevices, you can then go over it with some oil stain (ie
Minwax... yes I said it) and with some hard work can end up with a good
looking piece that looks like it's been glazed or antiqued.

The white line on the plywood is probably a glue line. You may have to
hand color that using a tinted lacquer or a felt tip pen.
