To remove water stains from upholstered chairs, use distilled water and an appropriate cleaner based on the cleaning codes for the furnishing. The fabric must be dried quickly after applying the cleaning solution.
To remove water spots from upholstery, Good Housekeeping recommends using distilled water to moisten the stain. After the stain is damp, fold several paper towels and place them over the stain. Press on the stain slightly, and use a blow dryer on the coolest setting to help push the water out of the fabric and onto the paper towels. Some types of fabric, such as rayon, may require cleaning with a fabric cleaner.
To clean a chair with fabric cleaner, opt for an all-fabric rinse. Mix the cleaner according to the directions on the packaging, then clean as recommended. In some cases, the fabric cleaner can be mixed with isopropyl alcohol to promote stain removal. Mix the cleaner with 2 ounces of alcohol, and clean the stain as recommended. Dry with a hair dryer set on the coolest setting to prevent further staining.
Water that contains minerals, such as iron, can cause discolored stains on fabrics. To remove mineral stains, use a product that is specifically designed to remove fabric stains caused by mineral deposits. After cleaning with an appropriate cleaner, apply a dry cloth to the area and weigh the cloth down with a heavy object to remove excess moisture.
