Cleaning product that's shown on TV (4)
I believe the answer is:
soap
I believe this is a double definition.
'cleaning product' is the first definition.
(product for cleaning oneself)
'that's shown on tv' is the second definition.
(soap opera is a type of TV show)
(Other definitions for soap that I've seen before include "TV entertainment" , "Bathroom item" , "Cleaner - long-running TV show" , "Washing substance" , "It has detergent properties" .)
