Water and wood: the stain guaranteed!First of all, if the water stain you want to remove is on an antique piece of furniture, we advise you to consult an expert. It would be a shame if your wooden furniture lost value due to a water stain! Also be aware that, in all cases, the faster you act in front of a water stain, the more chances you have to save your furniture, your parquet floor or your staircase. An overturned or simply forgotten glass, an overflowing flower pot, a little awkwardness, inattention ... and patatras, your wooden surface is stained. Whether it is oiled, waxed, varnished, treated or raw, there are different methods to remove a water stain. But whatever technique you choose, be careful and respect the drying steps and times.
Wooden furniture wears out over time. Take care!
Remove white stains from waxed woodWhen water has penetrated the finish of the wood, but not the wood itself, the stains are white and easier to remove. To remove stains from condensation on waxed wood there are 3 techniques. Follow the order to see what works and what doesn't. - The first technique is to rub the stain with mineral oil using a soft cloth and leave to act overnight. - If your first try with mineral oil did not work, you can try the same operation with white spirit, a solvent that will remove the stain in the wax layer. Don't forget to protect your hands with gloves! Once the stain is gone, you can then rub the entire surface of your wood with white spirit to avoid tarnished areas, then apply a layer of wax again. - If your attempts with oil and white spirit do not work, you have one last option: mix a little baking soda with toothpaste. Arrange your mixture on a damp cloth and rub in the direction of the wood grain, then clean the area with black soap. Improbable but radically effective!
Coffee tables are at great risk! Act as quickly as possible after a glass has fallen.
Remove dark spots on wood with sandpaperIf your wooden furniture, your staircase or your parquet has a dark stain, this means that the water has passed through the finish and has touched the wood. Arm yourself with 100 grit sandpaper and gently rub in the direction of the wood to remove the finish above the stain. Then pass a 150 grit sandpaper over the stain. Remove the dust then apply several coats of varnish to recreate the initial finish. To finish, homogenize the old and the new varnish with glass wool and wax the wood one last time. So, like new?

Bleach to remove dark stains from woodIf the stain is too deep, the sandpaper may not be adequate: you may sand the wood too much. To avoid disaster, bleach is your last resort. Protect your hands with gloves and apply bleach on your stain with a brush. Be patient and leave to act for a few hours while the stain discolours. Then use a clean sponge to clean the bleach and apply a layer of vinegar to the stain to prevent the wood from thinning even more. Let it dry and then apply light coats of varnish with a brush to recreate the original appearance of your wood. Here again, homogenize the old and the new varnish with glass wool and wax the wood one last time.
The most encrusted stains require a little work. But you will succeed!
How to remove a stain on raw wood?Raw wood is often lighter than waxed or oiled wood, so you can allow yourself to vigorously scrub the stain with a quackgrass brush, soaked in bleach. If the stain is really encrusted, sand in the direction of the grain of the wood with sandpaper so as not to damage your furniture. One last option: you can also lighten wood with oxalic acid, also called "wood lightener", available in all good hardware stores!
On raw wood, it will be easier to homogenize the surface after removing the stain.
