Sand off any hardwood finish using fine-grade sandpaper. Be careful to
sand off the finish only and not dig into the wood itself. Don rubber gloves.
In a plastic cup mix according to the instructions a small amount of oxalic
acid crystals with water. |
| 2. |
Apply the mixture only to the stained section of floor—if some gets
on unstained wood by mistake, wipe it up immediately using a white rag dipped
in white vinegar. Careful application is the key, so use a disposable plastic
spoon or similar conveyance to pour the chemical over the stain until the
entire section is wet. Allow it to penetrate for one hour. If necessary,
apply more solution to the stain and allow it to sit for another hour. |
| 3. |
Once the stain is gone (or as close to gone as it’s going to get)
wipe the area thoroughly with a clean white rag dipped in white vinegar.
Then rinse with water and dry with a clean dry cloth. When the wood is completely
dry, sand it to a smooth finish using fine-grade sandpaper. Apply wood restorer
one coat at a time until the bleached area blends with the surrounding wood.
If your floor has a shellac, polyurethane or lacquer finish, apply a comparable
coating to the area to seal it. |
