If you want a deep, rich stain on pine wood, you can do it, but plan it out. Buy a quart of your desired stain, the oldest one on the shelf. Do not shake, turn over, or disturb the contents. Take it home and let sit for a week. The stain pigments should be settled in the bottom of the can. Gently pour off the oils in the top half of the can.
Clean the wood with a tack cloth.
Stir the remaining liquor and spread evenly on the wood with a sponge brush. Let it soak in for 10 minutes, then wipe off with clean rags. Repeat if necessary.
