Remove as much of the spilled bleach as possible, and rinse the floor thoroughly with cool water and a mop. Dry the floor immediately to prevent the moisture from further damaging the wood.
If the wood fibers absorb the bleach, they may swell and cause the flooring to develop a fuzzy, splintered appearance. Use 100-grit sandpaper to sand the damaged area, then use 280-grit sandpaper to remove any remaining damage. The flooring should be smooth after sanding, but some discoloration may still be present.
Sanding can remove the color and sealant from the hardwood, making it necessary to refinish the floor. Wax or stain is typically recommended for wood flooring finishing. Choose a stain or wax that matches the existing style, and apply the product according to the directions on the packaging. After staining, a polyurethane topcoat may be used as a sealant.
