Hate to say this, but Welcome to Maple!! It's a beautiful wood, but
experience shows most people have better luck using it in a piece where
it can be left in its natural color...very blonde. It's tendency to
blotch is second only to cherry, and is just too great for most people.
Now, before I get flamed up one side and down the other, there ARE ways
to color maple. One way is to use a toner or glaze. Another is to add
color to the actual finish (shellac, lacquer, etc.). For these, you're
probably going to need spray equipment.
But in terms of coloring the wood itself, I know of only one decent
way, and that is glue-size. It's water-based, so you will not be able
to use a water-based dye on top of it. Wet the wood with distilled
water, let it dry, sand down the raised grain, repeat twice. Then coat
the board in the glue-size, wait for it to dry, then sand **very
lightly** to knock down any remaining fuzz. Then use an alcohol or
NGR-based dye and work quickly. I've never tried a pigment-based
stain, but I think that may work as well.
Personally, I still don't like the looks of the finished product, but
it's one way you can make it darker without spray equipment. Glue-size
is available from Homestead Finishing Products.
As for repairing your cabinet, you can try wood bleach. There are
three different types, and I can't remember which one works best on
dyes, so you'll probably have to Google it. This may or may not give
you enough color-removal, though.
