I'm refinishing a red oak floor in a foreclosure we bought recently. One room appears to have been the dog(s) latrine. I acquired a two part (gallon each) sodium hydroxide wood bleach sold by Duraseal/Minwax. Anyone have experience using a two part bleach? I have tried to read up on wood bleach, but most of the articles I came across seemed like they copied the same generic information from each other. The two part bleach is supposed to be the strongest bleach used to remove stains and/or lighten wood. Somewhere I read that bleach could damage the wood but the article did not give any further info. I don't have a lot to loose - the floor is already damaged.
I am thinking that I'll apply the bleach after the 60 grit pass - I presume several iterations of bleaching - I intend to use a small chip brush only on the stains and not the surrounding wood. And then continue with the 80 & 100 grit (guessing that I will need to stain the floor to hide the residual urine staining - I would prefer not to stain if I can lighten the spots enough). Does this seem reasonable or do I need to apply the bleach earlier/later in the sanding sequence?
Finally does anyone know what the shelf life of two part bleach is and what issues may arise if one uses "expired" bleach? I bough the bleach for a different project several years ago but that project got put on hold. The bleach containers have a note on the label that states that the bleach maintains its effectiveness up to 6 months if the containers are unopened. My two bleach containers are unopened but years old now.
Any advise, information, suggestions are appreciated. Worst case I carpet the room - killed the smell w/ Odoban and expect to do that again after sanding. TIA.
