In between the cracks of the floor boards I have a black discoloration in the bathroom. It is only near the tub so obviously it’s water damage. I have tried multiple solutions to no avail. I have used a mold remover product, Murphy’s floor soap, using peroxide only(bubbled when in contact), peroxide with baking soda, used darker old English on floor board and crack(looked worse), baking soda on its own(somehow stained deeper black than before), I used a nylon wire brush and #1 steel wool as well prior to a few previous interventions. I really don’t want to completely resand entire area as planks are fine and I feel I couldn’t sand between crevices where stain is. I have experience resanding and staining an entire house but don’t think it’s a good solution here. Any help appreciated. http://bit.ly/2LCUJzk via /r/DIY http://bit.ly/2V8wzwi
