How can I stain dark Sapele wood to reduce red tone?
I know this is way after the fact but if you want to brown up wood a cool method is to use Potasium Dichromate (Bichromate of Potash if your an old timey cabinet maker). Its a water soluble mineral that reacts with the tannin in the wood and accelerates the natural aging process. It won't eliminate the red completely but it makes it more of a brown tone and much, much darker. Its pretty safe to work with as a liquid but avoid inhaling the dust because its fairly carcinogenic.
