Unger RubOut Hard Water Stain Remover (RUB50) is a 16 oz (1 pint) glass treatment for window cleaning professionals who meet stains that a normal wash and squeegee cannot shift. Unger RubOut hard water stain remover tackles hard water marks, rust, mineral deposits, lime scale and soap scum on glass surfaces and restores the clarity of the pane.
What RubOut Removes
Hard water marks and mineral deposits build up where sprinklers hit windows, where water runs off frames and on shower doors. RubOut is made for those stubborn stains as well as rust, lime scale and soap scum, which makes it useful on household windows, shower doors and glass tabletops as well as the windows and doors of offices, retail stores, hotels and restaurants.
Apply it with a cloth or sponge, work it over the stained area, then rinse and squeegee the glass. The formula leaves a fresh scent after cleaning.
Inside the Formula
Unger's ingredient disclosure lists water as the solvent, silica (15 to 20% by weight), an ethoxylated alcohol (5 to 10%) added as a lubricant to prevent over drying, and sodium dodecylbenzenesulfonate (5 to 10%), a surfactant that reduces water surface tension. The green liquid comes in a bottle that measures 3.8" x 1.6" x 8.9" and weighs 1.2 lb, sized to fit in a cleaning kit.
Test RubOut on a small, inconspicuous area of the glass first. Keep a bottle of Unger RubOut (RUB50) in the kit for the stains your regular glass cleaner leaves behind, and finish with a standard wash and squeegee pass.
