Excessive heat and moisture can create white and cloudy spots on your hardwood floors. Placing a sweaty glass or hotplate on the floor for an extended period will also create the white, cloudy stains. These white stains will cause your flooring to look old and dingy. Remove the white stains as soon as possible. The longer the stains sit on your hardwood floors, the more difficult removal becomes.
Dry fresh white stains with a hairdryer. Set the hairdryer to a medium heat setting. Hold the hairdryer a few inches above the white stain and move it back and forth for several seconds.
Fill a small container with 1 tbsp of baking soda. Add 1 tsp of water and mix with a spoon. Dip the corner of a cloth into the mixture. Rub the white stains with the cloth in a circular motion for several seconds. Wipe the mixture off the hardwood floors with a clean, damp cloth. Continue to step 3 if the water spots are still visible.
Dampen a cloth with white spirit. Rub the white stain with the saturated cloth for several seconds. Continue to step 4 if the white stain is still visible.
Set an iron to medium and allow it to preheat for several minutes. Lay a white towel over the top of the white stains. Rub the heated iron over the white towel for several passes. Examine the progress of the stain over a few passes. Continue to step 5 if the discolouration is still present.
Fill a small container with equal parts white vinegar and olive oil. Dampen a cloth in the mixture. Rub the water rings with the cloth. Rub with the hardwood floor's grain until the spots are no longer visible. Buff the area with a clean cloth.
