    Default Best way to neutralize oxalic acid?

    I put some oxalic acid on a piece of furniture I am refinishing to remove/lighten some stains (deck cleaner). It caused the stain in that area to be about two shades lighter than the other parts.

    What is the best/recommended way to neutralize? I have read that 50% ammonia/water. Also saw mention of baking soda.

    I'll have to sand off the poly finish anyway and start over.

    Many thanks

    Vinegar. Yes, it's an acid too, but it works.

    I've seen pictures of mrleft8's and Keith's work. I'd do anything they say, but I've always used baking soda. Dissolve oxalic AND baking soda in distilled water only.

    Thanks. I rinsed with water. Maybe not enough. Package didn't give a lot of detail but it was deck wash.
