    Bleaching Wood To "near White"

    OK folks, in your bag of tricks, what do you use, how, etc. Am interested in trying bleaching. Maybe on some white birch, redwood, and sycamore.
    Thanks in advance,

    Give some two part "A" "B" bleach a try, it should do the trick. I've used it to bleach streaking/staining out of red oak successfully. Multiple applications will turn the wood almost pure white. Its available from a few different manufacturers. Rockler and Woodcraft both carry it, believe Kleen Strip is one brand Be careful though, wear gloves and eye protection, this stuff will burn your skin in a hurry.

    Alternative is a single part Oxacalic (spelling?) acid bleach. I picked it up at the local Hirschfields paint store. Haven't yet had a chance to try it out, but its supposed to bleach aged or darkened woods back to their fresh cut color. I don't think it will bleach lighter than when the wood was fresh though.

    Good luck.

    Kim, oxalic acid is used to remove black mineral stains from wood. It has minimal affect on the natural color of the wood. What you want is the A/B two part bleach.

    Do most of your sanding before bleaching. The bleaching effect does not penetrate too far and agressive sanding after bleaching can remove much of the bleached wood layer.

    Howard,
    Thank you. Wondered how deep the bleaching effect went.
