After bleaching, wipe the wood clean with a damp cloth. To remove any residue, neutralize the wood thoroughly; use an ammonia solution for oxalic acid, a borax solution for laundry bleach or two-part bleaches. Wash the bleached wood thoroughly with the appropriate neutralizer; be careful not to overwet it.
Bleach is a strong oxidizer and will oxidize away the color of the floor, Meaning the actual pigment in the wood is gone. The stain you see is where the bleach destroyed the original color, so it's not really something you can just wipe off.
Make sure that any previous application of bleach has been properly neutralized and is thoroughly dry before attempting to apply a different bleach product. Failing to do so could result in a harmful chemical reaction.
Bleaching Techniques. Whatever bleach you use, remember that the results are permanent -- you may be able to restain if you make the wood too light, but uneven bleaching is very hard to remedy. Make sure the wood is absolutely clean, and touch it as little as possible. The bleach must penetrate the wood evenly.
Make sure to neutralize & clean your piece after completing the bleaching process prior to finishing with a 50/50 white vinegar and water solution. Lightly sand the wood with 220 grit sandpaper after bleaching and neutralizing. For best results, always remove the finish prior to bleaching.
After rinsing, apply a neutralizing agent like a vinegar-water solution (1 part vinegar to 10 parts water) to neutralize alkaline residues left by bleach. Rinse again with clean water and dry the floor thoroughly. Avoid prolonged exposure of bleach on hardwood to maintain its natural appearance and integrity.
Allow to dry at least 8 hours. Rinse with water and clean cloth or sponge. Keep rinse water clean. Dry overnight and sand with 120 grit sandpaper.
When it comes to cleaning hardwood floors, many people are unsure of which products are safe to use. One of the most common questions asked is: Can you use bleach on hardwood floors? The answer is no — bleach should never be used on hardwood floors since it can cause major damage.
There are three types of clear topcoats used to seal natural wood or bleached furniture – polyurethane, polycrylic, and wax finishes.
Bleach needs to be neutralized after it has accomplished its intended purpose and prior to sink disposal.
One approach is to sand the affected area lightly and apply a matching wood stain to blend the spot with the surrounding floor. Alternatively, you may need to refinish the entire floor for a seamless appearance.
Don't use vinegar on unsealed wood: If your wood furniture is unsealed, vinegar can penetrate the wood and cause damage. Only use vinegar on sealed wood furniture. Don't use vinegar on waxed or oiled wood: If your wood furniture is waxed or oiled, vinegar can dissolve the wax or oil and cause damage.
If the bleach solution dried on the wood, sodium hypochlorite crystals will form in the top layer of wood. These crystals are extremely difficult to dissolve and rinse away.
The crystals you are observing are salt crystals. That's because the sodium hypochlorite active in Clorox® Disinfecting Bleach breaks down into salt and water (a big part of what makes it so environmentally friendly).
Avoid overlapping onto the sections that have already been bleached. * Leave the surface wet for 30 minutes, then neutralize it with a 50-50 solution of white vinegar and water. Rinse with warm water. * Let the wood dry for three hours before you decide whether it needs another application.
How long should I leave oxalic acid on the wood? At a minimum until it is dried. You can also apply multiple coats until you get the desired affect you are looking for. After which, then you can neutralize the oxalic acid and clean up.
The natural pH of wood is slightly acidic, and bleach is a basic solution. As a result, use of bleach on wood shifts the pH from near neutral pH to a basic pH that will damage the cellular structure. Bleach corrodes metal fasteners, screws, and nails. Bleach can cause damage to surrounding plants.
Laundry Bleach: This mild bleach can solve most refinishing color problems, from stain or filler not removed in stripping to ink stains and water spots. It works well for blotchy areas and for slight overall lightening, but it won't change the color of the wood drastically.
Cleaners containing chlorine bleach are commonly used to clean decks but they are not recommended for cleaning treated wood. Excessive use of chlorine bleach containing cleaners (sodium hypochlorite or calcium hypochlorite) can damage treated wood leaving it with an unnatural whitewashed appearance.

Unfortunately, a bleach stain is permanent. Once bleach has made contact with a fabric, the stain will have set, stripping the colour or dye from the fabric. When it comes to removing bleach stains, the approach you should take is one of restoring the colour that has been lost rather than removing the stain.
If you used a penetrating oil stain, you may have allowed the stain to build up too thick a coat on the surface of the wood. Penetrating wood stains are not intended to be a surface finish. If applied too thickly, they won't dry properly and will remain tacky to the touch.
