Oxalic acid?
I have some dark water stains on my hardwood oak flooring that I would
want to remove. I read here that oxalic acid is a good way to approach this. The problem is I cannot find any. At Home Depot they looked at me like I awas from another planet and had never heard of it. Does it perhaps have another name so I can find some? TIA |

TIA Some deck cleaners are oxalic acid. There's usually the bleach based cleaners and then the oxalic acid based cleaners and then the lye based cleaners. Read the labels to get the right one. If the floor has any kind of finish on it, all bets are off as to what will happen. -dickm |

Barkeeper's Friend contains oxalic acid. You could make a slurry of it with water. It is also slightly abrasive. It will take dark stains out of wooden countertops. Of course, whatever course you try, you will most likely have to refinish those areas. Most any product will damage the top finish to get at the stain. -- Wayne Boatwright ******************************************* Date: Wednesday, 09(IX)/10(X)/08(MMVIII) ******************************************* Countdown till Veteran's Day 8wks 5dys 18hrs 3mins ******************************************* When you're having a bad day and it seems like people are trying to **** you off, just remember: It takes |

TIA If you want almost pure oxalic acid, get Savogran Wood Bleach. Here is a link to the MSDS: http://www.savogran.com/Information/Wood_Bleach_MS.pdf I have a True Value hardware store. The True Value stock number is 602979. I'm sure it's available at other hardware stores, also. As others have noted, this might not work for what you are trying to do. But it's probably worth a try. |

If it does remove the water stain, it will leave unsightly marks. Have you tried mayonnaise? If that doesn't work, a refinishing floor job is in your future. |

The problem is I cannot find any. At Home Depot they looked at me like I awas from another planet and had never heard of it. Does it perhaps have another name so I can find some? TIA Hello, Oxalic Acid can be found as the active ingredient in many deck cleaners. Just read the label. You might also be able to find Oxalic Acid crystals in a good paint or hardware store. It is also found in single component "Wood Bleach". Again, read the label. You will have to strip off the remaining finish above the water stains so you can apply the acid, as a concentrated Water solution. The problem you are going to have is that in addition to removing the black stains, it will lighten the wood just enough to make it obviously different. That means stripping off enough of the finish and treating a large enough area such that you can make the change in color occur at a visually natural place on the floor. If you use Oxalic Acid, let it dry over night and don't let any people or pets touch it or eat it. It's fairly toxic. After it has dried and assuming the floor doesn't need a second treatment, wipe it up with a damp rag. The solid will make you sneeze big time so don't dry brush it off the floor. Dry brushing will just sweep the smallest particles into the air. Go over the floor with a Water solution of Borax to neutralize any residual acid. Wipe down the Borax dampened floor with some fresh rags, let the floor dry, and you are good to go. Good Luck. |

If that doesn't work, a refinishing floor job is in your future. Why would you caution against using it on wood? Oxalic acid is the "original" wood bleach. In good paint stores it is sold as wood bleach. It is the best way that I have found to remove iron based stains. Works well on stainless steel kitchen surfaces too. Oxalic acid is somewhat toxic. However, that is a matter of how much you ingest. Oxalic acid is found in small quantities in green, leafy vegetables like spinach. It's also the precursor of the most common kidney stones (calcium oxalate.) |

The amount you could ingest by touching it and then accidentally putting your fingers to your mouth is significantly greater than what you would ingest from green, leafy vegetables. The bigger issue is actually sneezing. You haven't really sneezed until you've gotten even a little of the dust in your nose. Good Luck. |

Oxalic acid?
Well - just an update to close the loop. I tried some regular bleach
on it and now it really looks like hell. The wood was not originally stained, just the verothane or whatever giving it a slightly yellowish oak look with a sheen on it. Now it is white with really dark blotches. lol I think I will take the tried and true route and pick up a few squares of the hardwood - I'll have to trim a bit since the new stuff is metric and mine is old enuf to be all imperial measurements. I'll just knock them out and replace and then spot sand to the same level and touch it up. Has tro look better than it was and is now..... thanks for the information anyways! |
