i also use a sock!...not the inside rough part!...the out side part!..its smooth,especially if u got sum new ass socks like sum nike or sum shit...so just like stick ur hand in it and on ur finger,damp it wit ur tounge gently, not to get it so wet to leave new streaks,but just lightly and rub the smudges and stains off it!..u will barely leave sum light new streaks cuz its wet at first but keep rubbing em softly...they will eventually rub out cuz its just a lil saliva u feel me?!.......i find it works good and u dont really have to worry bout getting ur t.v wet at all and ruin it!...just be gentle and rub lightly....it will take a lil time depending on how dirty ur screen is but like i said ,me personally,..it works good!.....good luck!!!
