Unless it’s written into the purchase agreement, there’s no legal obligation that a house you’ve bought has to be clean before you move in. The previous owner is generally required to sweep the house, but that doesn’t guarantee everything will be spotless upon your arrival. If possible, discuss the cleaning requirements with the real estate company before moving in.

Professional window cleaners typically use either a white vinegar solution or a commercial hard water stain remover to clean hard water stains on windows. A common vinegar solution for this purpose consists of one cup of white vinegar mixed with a gallon of distilled or bottled water.

Alternatively, they may use a commercially available hard water stain remover and a scrubby pad, followed by a complete cleaning.

Yes, in most cases, you can add a few drops of Dawn to a spray bottle full of vinegar to remove hard water stains.
