Hi, Cheryl. Relax. We will try to make it better. There are several different kind of stains and therefore several different products that work on them. The first thing that I would do, after ALL old paint and clear film finish is off is to apply household bleach straight from the bottle. Let this work for a while and see if it has any effect. If it does and the stains are out, or if it does not after a half hour, apply one cup of white vinegar to a gallon of water to neutralize. If the bleach didn't work, go thru the same process with oxalic acid, sold ounder the trade name Wood Bleach and other names at the home centers. Neutralize with bleach in the on cup to one gallon of water ratio. One of these should work but let us know if it does not. Whatever you do, wear chemical resistant gloves and covering eye protection. Use a dust mask when you mix the oxalic acid according to label directions.
You might also check the www.citristrip.com "Ask the Experts" board. There is a lot of info on this subject there. I have never heard of your concoction, but Citristrip is a pretty safe stripper. Chemical burns are a possibility so use the protection as above if you try it.
Good luck and come back if you have further problems. Henry in MI
