it takes approximatly 3 times longer to remove then it does to retain.
Commercial displays do not have the "cleaning" process because you quickly will run out of time to strip(i.e. TV on longer then 8 hours a day)
TV on more than 6 hours a day. TV on for 6 hours, loading up the electron box; three times that (18 hours) per day to clean them out; that totals 24 hours. It's an easy mistake to make.
