To remove water spots from windows, use a mixture of vinegar and water or a commercial glass cleaner. Apply the solution to the spots and let it sit for a few minutes before scrubbing with a non-abrasive sponge. For stubborn spots, try using a soft cloth and rubbing alcohol. Regular cleaning can prevent the buildup of hard water stains.

Water spots are caused by mineral deposits left behind from water evaporation. Regular cleaning with vinegar or glass cleaner prevents buildup. For persistent stains, rubbing alcohol or a specialized cleaner may be necessary to restore the glass's clarity, making your windows look sparkling clean.
