It may get into a lather (4)

I believe the answer is:

soap

(Other definitions for soap that I've seen before include "Cleaner - long-running TV show" , "Coronation Street?" , "Cleansing substance" , "Cleansing TV serial drama" , "type of TV programme" .)

I've seen this clue in The New York Times.
