I caught the segment on the screen cleaner by Stacy King.Use 2 drops of dishwashing liquid(it looked like the blue one)added to a few oz.(approx.3)of 91% alcohol(looked like red label from wally world)in a small(tiny)spray bottle.Spray the screen a few times,"dab" the excess off and wipe clean with a recommended cloth.The hard water spot stains that remain can be cleaned with vinegar.He soaked a blue shop paper towel with vinegar and pressed it on the screen making sure to press out the air bubbles,so it makes contact with the entire screen.This should desolve the hard water stains after a few minutes maybe more.Then "dab" the excess off,wiping back and forth may cause scratches.Then spray with above solution and wipe clean with cloth.**as a precaution I am going to "dab" a lot the first few times I try it.If you catch one little piece of that hard stuff it will scratch your screen.**I havn't tried this yet so proceed with caution.It always looks easy when the pros do it!lol.
