Help with refinishing

They sell a chemical for removeing the mold/black stains from wood. I will lok it up when I go out to the shop. Just have to wit for my back to charge up.

You need oxalic acid to remove those stains.

Al is right, you need oxalic acid. And believe me, there will be nothing left alive after putting that on it. use the proper precautions. Water neutralizes it, so I usually use it outside, where I can dose it with water, also the sun helps speed the process. I always start with a dilute solution, most people advocate a 1:1 ratio of oxalic to water. And remember to add the acid to the water, not the other way around. Just common sense and remembering your high school chemistry and you’ll be fine. I used it on an 18th century cherry bench to remove black spots. Of course, it does take out all the color wherever you put it on, so be prepared to stain (or paint) it, otherwise you will have white spots instead of black. Good luck!

Thanks Robin and Al. My brother Greg3g told me the same thing. As far as chemistry, I think I will be able to handle it, I am a Haz-Mat tech for the fire dept.

Thanks again gang.
