How I can remove water stains from Hardwood Floors?

I sanded the floor and the spot that used to be black is now gray. What I do.

1) To remove a cloud of white smoke or white spots, buff dry with a soft cotton cloth and a very mild abrasive such as toothpaste whitening, self-polishing compound, or snuff ash mixed with mineral oil until the stain disappears. 2) Start by removing all traces of wax or surface. Use fine steel wool to remove the wax and sandpaper to remove the surface finish. Depending on the size of the penalty area, the sand by hand with a rubber block or sand grinding machine with an orbital sander. In both cases, first in a 80 – or 60-abrasive grains and 100 grains of sand. Arena just until the edges of the joints affected. 3) Mix oxalic acid crystals (available at paint stores or hardware) in a cup (8 fl oz/250 ml) or hot water and stir until dissolved. Continue adding crystals that dissolves more. 4) Pour, brush or sponge the solution onto the stained area. When completely dry, brush off the crystals and repeat the process until stain is gone. 5) the stain or seal, then terminate the affected area. Or, if the issue is too much, use the detection method and return layer across the floor.
