With which to clean top of orange juice cans (4)
I believe the answer is:
soap
'with which to clean' is the definition.
I can't tell whether this definition defines the answer.
'top of orange juice cans' is the wordplay.
'top of' suggests taking the first letters.
'juice' becomes 'sap' (juice from a plant).
'cans' indicates putting letters inside (to can could mean to contain).
The initial letter of 'orange' is 'o'.
'o' inserted within 'sap' is 'SOAP'.
Can you help me to learn more?
(Other definitions for soap that I've seen before include "TV programme - sudsy bar" , "Cleansing TV serial drama" , "Serialised drama" , "Cleaner - long-running TV show" , "Bath tablet" .)
