Water stains on wood are of two types: white and dark stains. White stains are caused by moisture that has seeped into finishes on wood surfaces but not yet wood. Condensation on the bottom of the cup on a wooden table can cause round white stains. Dark stains appear when water seeps through the finish and into the wood, such as stains on the wooden floor where the pot is located. This article will show you ways to clean white and dark stains from wood.

Steps

Method 1 of 3: Remove white stains

1. 

   Soak mineral oil in a soft rag and rub it on the stain. Leave it on overnight and repeat it again if the stain does not seem to fade.

2. 

   
   
   Use a soft cloth to rub white petrol over the stain if the mineral oil isn't working. White gasoline is a mild solvent that can remove stains that soak into the wax on the wooden surface but have not yet entered the finish.
   • Wear gloves and do this work in a well ventilated area. Leave for a few minutes for the chemical to take effect.
   • If the stain is clean but looks faded, rub white petrol over the entire surface of the wood.
   • Apply new gloss paint to the surface of furniture.

3. 

   
   
   Use a mixture of baking soda and toothpaste if white gasoline won't work. The proportion of ingredients in the mixture does not matter, but you should not use gel toothpaste.
   • Spread the mixture on a damp rag and rub the stain along the wood grain lines until clean.
   • Wash off with oil soap.
   • If the stain doesn't come clean at first, try it again.
   • Use good quality wax to polish furniture.

Method 2 of 3: Remove dark stains with sandpaper

1. 

   
   
   Use sandpaper to scrub the finish on the stain, rubbing your hand gently along the grain of the wood.
   • Use 100-grit sandpaper, then grind the edges with 150-grit sandpaper.
   • Remember not to rub too hard to avoid losing the wood on the surface.

2. 

   Scrub the stain with 150 grit sandpaper; You have now removed the finish on the wood surface. Grind around the stained area with # 0000 steel wool.

3. 

   Use a lint-free cloth to remove dust after sanding.

4. 

   Apply several layers of varnish to the surface for a full color finish with the original finish.
   • Make sure the varnish does not stand out, but it looks natural.

5. 

   Grind the edge of the new varnish with steel # 0000 cloth to smooth out the supernatant between new and old varnish.

6. 

   Polish good quality wax wood. advertisement

Method 3 of 3: Remove dark stains with bleach

1. 

   Bleach the wood with chlorine bleach if the stain is too deep and cannot be removed with sandpaper.

2. 

   Put on rubber gloves and scrub the stain with a brush.

3. 

   Leave it on for a few hours. The stain will fade to almost the same color as the original wood, but this is a slow process.

4. 

   Wash off the bleach completely with water and sponge and prevent wood discoloration.

5. 

   Use vinegar to neutralize the wood. This will prevent the paint or varnish from bleaching when you apply it to the wood.

6. 

   Wait for the wood to dry completely.

7. 

   Paint on the wooden surface if necessary and allow to dry completely.

8. 

   Apply several layers of wood paint or varnish to the wood surface to match the color of the original finish.

9. 

   Grind the edges of the new varnish with # 0000 steel wool to smooth out the supernatant between the new and old varnish. Wipe off dust with a lint-free cloth.

10. 

    Polish good quality wax wood. advertisement
