We recently replaced all our old oak trim and doors (a medium to dark stain color) with birch in a lighter stain. Our entry door is fir -- and was just replaced a few years ago so we don't want to replace it again. I stripped the old finish off and am down to bare wood, but the wood itself is more red than the birch. Is there something I can do to the wood before applying the stain to get it to match to the birch better? I was reading about the two part wood bleach actually being able to lighten up the tone in the grain of the wood --- is that the product I should use? Any other recommendations?
