You probably want to use the remove command. For example:
newScale("akzeptabilität", 7)
.settings.before( newText("left1", "1
(am unakzeptabelsten)") )
.settings.after( newText("right2", "7
(am akzeptabelsten)") )
.settings.slider()
.print()
.settings.log()
.wait()
.remove()
,
getText("Skala2")
.remove()
