To remove water stains from wallpaper, particularly those caused by tannins, you can use a simple solution involving bleach and distilled water.
Understanding Wallpaper Water Stains
Often, what appears to be a water stain on wallpaper isn't caused by the water itself, but rather by substances dissolved by the water from the material behind the wallpaper. As the reference notes, "Most 'water stains' are not actually caused by the water itself but from the tannins in the wood behind the paper, which dissolve when they come into contact with the water." These tannins are pigments found naturally in wood that can bleed through materials when wet.
The Recommended Solution
Based on the reference provided, these types of tannin stains "can be eliminated with a little bleach mixed with distilled water."
While specific proportions are not detailed, the general approach is to create a mild solution. Distilled water is preferred as it is free from minerals that could potentially leave their own residue.
Method Overview:
- Identify the stain area.
- Prepare a solution using a little bleach mixed with distilled water.
- Apply the solution carefully to the stain (it's often recommended to test in an inconspicuous area first, although the reference doesn't explicitly state this, it's standard practice).
- Blot gently rather than rubbing vigorously, which could damage the wallpaper.
- Allow the area to dry.
This method specifically targets the dissolved tannins, which are a common cause of brown or yellowish "water" stains. (Note: For different types of stains, like oil or grease, a different approach such as using a white eraser might be suggested, as briefly mentioned in the reference).
Remember that the effectiveness can vary depending on the type of wallpaper and the severity and age of the stain.
