The best way to prevent hard water staining from returning or occurring in the first place is to NEVER clean your windows with a hose or let the sprinklers hit the windows. If this tap water is left to dry on your windows it will slowly start to build up and create hard water staining.

Having your exterior windows cleaned on a 6 month regular basis will prevent water stains from ever building up to the point of requiring restoration.
