But I do remember at least one service tech who asked if mom and dad wanted him to clean the glass (on a B&W set). And when he showed them how much smoke film was on the face of the crt and the inside of the safety glass, mom and dad were astonished. And the picture was visibly much sharper and brighter after the cleaning.[/QUOTE]
That's why I always carried some Windex and paper towels on service calls.
