Can anybody tell me if it's possible to bleach 3/4" Maple, birch, or even poplar completely through the wood. If not then how deep will bleaching penetrate?

Thank you for your comments and I to was thinking about vacuum to see if it would penetrate. You all are my favorites

@Sid Bright, In order to get bleach or anything else to penetrate any significant distance under vacuum, the wood needs to be bone dry. However, even this won't help much when using wood bleach (a mixture of sodium hydroxide and hydrogen peroxide) because the bleaching process is a chemical reaction in which the bleach is very quickly neutralized as it comes in contact with the extractives in wood. If you are bleaching an open-grained wood the bleach would penetrate slightly deeper than it would in closed-grain wood.
