Removing water spots from windows requires the correct tools and a regular cleaning schedule. These spots are often left behind after the windows have been cleaned with regular glass cleaning products. Water spots are caused by a buildup of mineral deposits on the glass, so homeowners might need to use special cleansers and tools to get clear windows. The best tip for removing water spots from windows is simply to purchase a quality product that is designed for this purpose and to follow the instructions for using it.
In the case of windows and glass exposed to hard water, such as those in a shower or bath area, water spots can be removed by using basic household acidic products. These products include vinegar and lemon juice. If the hard water spots have built up over a long period of time, stronger acids used in professional cleaning might be necessary. Gloves and eye protection should be used when working with strong acids and cleaners.
When cleaning windows exposed to the outdoors, homeowners should first remove any surface dirt using a rag and then wash the window with a mild cleansing solution. The water should then be removed with a squeegee. Cotton T-shirts, cloth diapers and microfiber cloths are effective at drying glass without leaving streaks or creating a static charge on the glass.
After the glass is clean, removing water spots from windows can become the focus. Some experts recommend wetting the glass again and then either scrubbing it with super-fine steel wool in the case of small panes or using special cleansing powders on larger panes. Homeowners can mix these special cleansing powders with water to form a paste. The paste should then be scrubbed over the spots using a damp rag, and the windows should be double-rinsed. Employees at home improvement stores should be able to help consumers identify which cleansing powders can be used for this purpose.
Cleaning the glass at least once every six months should make a big difference in the ease of removing water spots from windows. After the spots have been removed, homeowners can apply a special polymer sealant to prevent the spots from returning. The sealant should be reapplied after each washing to create a permanent barrier against the spots.
Homeowners might consider purchasing windows with self-cleaning glass to reduce concerns about removing water spots from windows. This glass includes a chemical compound that causes organic materials on the glass to disintegrate when exposed to sunlight. It also allows water to run off the windows in sheets instead of in beads, preventing water spots from forming altogether. These windows need to be cleaned about half as often.
