Please advise with help on removing dark stain from red oak? We had a Jacobian stain on our red oak floors and had a flood and had to replace a lot of the word now we are wanting to go with a much more natural finish but this is what our stairs look like after they have remove the stain and bleached them. how do we get the rest of this stain out and is it even possible? The main floor has been stained with a seal called Nordic seal and it looks good but there are some Nail heads that still have dark stain from previous around it any advice would be appreciated
