Fold a paper towel to make a thick pad. Apply white vinegar to the pad, and place it over the stain for 5 to 10 minutes. Remove the pad.
Mix a solution of one part water to one part white vinegar in a spray bottle. Spray the hard water stains with the solution, and allow them to sit for 5 to 10 minutes.
Spritz the entire surface of the appliance again with a small amount of the water/vinegar mixture. Wipe away and dry with paper towels to make a streak-free shine.
