I've used oxalic acid on my deck (which works great, by the way) but never imagined using it on poplar to get rid of the green. Great tip. I'm going to give it a try some time. Thanks.
Many thanks for this and your other videos. Some hardware stores sell "wood bleach," which is simply oxalic acid. FYI, dilute oxalic acid solutions are also great at removing rust stains.
Excellent advice. I always like working with poplar - relatively good value, stable and quite easy to cut/shape but the color doesn't inspire me to do anything other than paint it. This technique will be great to experiment with and show off its grain.
So… you just rinsed it off with a hose. But I have a project that is piece of furniture basically. And spraying it isn’t really possible. Any other suggestions on how to rinse it?
I like this technique more than the dye/stain approach you showed previously. The poplar becomes very neutral in color, like maple. Following the oxalic acid, you should be able to choose any stain without being committed to an orange/red one. Thank you, Skylar!
That is correct. However, I don’t love working with acids and it kind of freaks me out handling it. After I filmed the video, I washed my hands about 20 times and kept feeling that maybe I still have some acid on me
Oxalic acid is also used to remove dark water stains on furniture during the refinishing process. See dashner design and restoration channel for examples of this. Quite amazing. Thanks for showing this use, I was wondering if you knew about it when you showed how to stain poplar.
I saw a few videos of dasher design ( amazing content)and it’s possible that’s where I first saw the oxalic acid. I don’t use it much as I rarely work with poplar and when I do is for painted projects
So, poplar can have greens, browns, and even purples. Does this method only remove the green? Or will it affect the browns and purples as well? Regardless, excellent work! In a similar vein, have you tried using lye on cherry wood? Essentially ages the cherry in moments, giving it a deep, darker red colour.
Hi Asbrand. It will remove the green and not affect the blacks. It will give it a warmer all over all appearance. I love using Lye on cherry wood. Just did a video on that a few days ago
