Hard water spots can be removed from windows using a solution of equal parts water and white vinegar. Spray the mixture onto the affected areas and let it sit for 5-10 minutes. Gently scrub with a soft sponge or cloth and rinse with clean water. If needed, use a paste of baking soda and water for extra scrubbing power. For stubborn stains, a commercial hard water stain remover may be required.
