  1. This comment isn’t about hickory but not sure where else to post this on your site:
    please stop presenting oxalic acid as a stain remover for wood. It doesn’t work on most stains, and makes some stains worse. The internet fell for the oxalic acid myth hook, line, and sinker: it is complete crap, and people should test it out before copy/pasting this “wonderful product” in their blogs and videos. I’ve ruined some lightly stained wood by trying oxalic acid on the stains: much worse.

    1. Hi Susan, I’m sorry to hear oxalic acid caused issues for you—it’s definitely not a one-size-fits-all fix. I use it regularly in my refinishing projects and have tested it on stains where it works and where it doesn’t—including ink, which I’ve found it can actually make worse.

      In my full guide (https://boldwallflowers.com/oxalic-acid-on-wood), I explain that it’s effective on organic stains like rust and water rings, but not on ink, grease, or dyes. I always advise spot testing—but also warn that it can significantly lighten the wood in that area.
