    So glad I found this fix. I had 3 black rings on my red oak dining table. I had tried other methods to remove the rings with no success. It took less than 10 minutes for the ugly rings to disappear. Thank you, thank you!

    Would this work on a veneer surface (that’s what I think it is anyway) that is blotchy, deep red toned, and a handful of shades darker than it was originally? I had put a lacquer over it, then it dried patchy, so the next day I took citristrip (worst mistake) over it all and it left me in tears because it now looks so horrible. These vintage pieces are difficult.

    • @hardwoodartisans
      @hardwoodartisans  8 років тому +5

      +Devora Daniel A few additional general points regarding this process. The Oxalic Acid process will work on an unfinished desk from the 60's. It works on penetrating oil finishes, like Danish Oil, Teak Oil, Linseed Oil, Wax Based Finishes, etc. Regarding flooring repairs, the finish (polyurethane, varnish, etc) needs to be removed first. Then the acid may be applied. I have never found a need to reverse the acid or neutralize in any way. The key thing to watch out for is that the wood has fully dried, that there is no moisture from the acid process left in the wood. I will run a hair dryer over the wood, extracting any remaining moisture (it will bead up as the wood is lightly heated). I then let the wood stand for a day or two.

I didn’t think it was that bad until I used danish oil to seal it which made the marks 10times worse. I have followed this tutorial for the last 2 day’s and after 2 applications over 24 hours it isn’t working for me... can I email photos for further advise please, I’m not sure what to do x x

    Hi Pat and thanks for the video.
    I have a problem that someone vomitted (!) on the wood floor of a cottage I rent. Although they cleared it up it's left a stain. Would this work on that? Will I be left with a big white splodge? The whole floor has a light colour stain. Would I need to remove that from the whole floor in order to keep an even finish?

    Hi-Thank you so much for posting this video. You've mentioned that lacquered finished furniture requires a different method. I was wondering what method do you recommend to get stains (stained legs from just using/denim dye stains) out of matte lacquered solid oak furniture. Will I be able to still use oxalic acid? I would love to get some of your expertise. Thank you so much.

    • @hardwoodartisans
      @hardwoodartisans  7 років тому +1

      Dye stain is just that. It dyes the wood. Oxalic acid is a neutralizer, and I do not think it would be of any use.
      I am extremely cautious to give any advice here, but it sounds like Acetone may be the only way to remove the stain. However, Acetone will melt lacquer......this may result into a refinish project.

  • @khadijameredith7586

    Hi :) Really nice video; thank you! Quick question... does this acid need to be rinsed or neutralized before finishing? Mine would be for heavy wear patterns and staining by doors, etc., in a very old wooden floor, and will eventually be sealed with a water-based floor finish. I guess my point is that since it's a floor taking heavy abuse, I'm afraid that all of my hard work could be undone by the acid lurking underneath, possibly preventing an optimal bond with the finish, or even the acid continuing to break down the integrity of the wood...? Thank you for your help! :)

      Once you apply a clear coat you lose the ability to apply heat or any other type of cleaning or repair product as it will dull the finish. We apply these techniques to solid hardwoods only and only those that have been finished with a natural Danish oil hand rubbed finish.

    @carolinaviterironald1974 7 років тому

    I am refinishing an old love seat and decided to finish it with Danish Oil but it turned horribly yellowish, plus it was made out of different kinds of wood that show more when finished. Can I use this method to remove the Danish Oil and then bleach my furniture to match the colours? I am sick of sanding this thing...

    • @hardwoodartisans
      @hardwoodartisans  7 років тому +1

      Hi Carolina,
      The question posed here is more of a refinishing problem and less of a wood bleaching problem. Basically, the answer is "no, you cannot bleach different woods and expect the colors to blend. Because you have different woods in the piece (which is not unusual in this type of application) you will need to apply a fairly dark stain to cover and blend the different woods. Heavy stains generally require a lacquer finish as a top coat to hold the color in, so Danish oil will not work here.
      I always reserve giving advice on furniture I have not seen nor touched. My advice is just that, my opinion of a problem I have not seen. I suggest taking the piece to a refinishing shop and having them apply color and lacquer. You may have been going for a natural look for the legs, but in this application that is probably not possible to achieve. Good luck and be patient.

    • @hardwoodartisans
      @hardwoodartisans  8 років тому +3

      No. That said, I am not a chemist, but I do understand that the cause and effect are the same.
      What actually happens to a stain in wood when oxalic acid reduces, the stain is not removed. Rather, the oxalic acid changes the chemical makeup of the ferrous to ferric acid. In other words, it changes the iron in the stain from one isotope to another, which is colorless.

    Mark, Thanks for the awesome tip! I just discovered several unfinished mahogany veneered doors that have been sitting in an addition on my house that incurred a leak a few months prior. Unfortunately the doors sat on a wet floor and the bottom rails are stained. You caution about using this process on veneers. Could you explain your concern and how you might proceed (I assume all risk and at this point the doors are already damaged).
    Any help would be greatly appreciated.

    • @hardwoodartisans
      @hardwoodartisans  8 років тому +2

      Hi Carl, the concern I have about this process as it applies to veneers is that
      veneer does not like water saturation. There is a risk of de-lamination. As
      these doors have already sat in water and appear undamaged (less the
      stains), this process is probably safe to try. Go ahead. Please take some
      before and after pictures for us!
