we are refinishing our wood floors and found dark pet stains. someone told us to pour coke over them and it will take out the black. others have said to sand and then take bleach and rub out the black. the bleach seems to have worked in one spot but want to know if this will damage the floor and are they any other suggestions OTHER than replacing the boards. help fast the carpet is out and we need to get started soon. the wedding is in a month. forget to tell you that.

Urine stain on wood floors

If the stains can not be sanded out, it is usually recommended that the boards be replaced. This usually requires a professional who can remove boards from an inconspicuous area for the replacement. New boards can be installed in the inconspicuous area. I once owned a home where pets had obviously been kept in the office. The refinisher stated that the stains were deep into the wood and could not be sanded out, so I carpeted the area. Best regards.

Urine stain solutions

Urine stains can be sanded out on the rare occasion, but generally the urine wasn't discovered in time and it has soaked into the wood. When you sand it, beware. The smell can be overwhelming.

(Keep this in mind the next time you get ammonia near the floor. DO NOT clean the floor with ammonia, even diluted.)

Bleach can work, but if you choose to stain the wood, the stain will set differently. This is the process used to pickle wood. The finish can also be absorbed by the wood differently once it has been bleached in only one area rather than uniformly as in pickling.

We had some luck with oven cleaner. Let the cleaner sit on the stain for about 15 minutes. Wipe it off with a slightly damp rag. If the stain hasn't lightened significantly, don't do it again. If the stain has lightened, but isn't gone, repeat this step. If the homeowner wasn't satisfied, then we'd just cut out the wood and replace it with a new plank and sand and finish the floor like normal.

It isn't necessary to get a plank from another place in the house. Just get a replacement plank the same grade and species as what is on the floor now. Once you sand it, you won't be able to tell unless it is photoreactive. If that is the case, then only time will allow the new plank to blend into the floor.
