Washing liquid containing red fruit (6)
I believe the answer is:
lychee
'fruit' is the definition.
(lychee is a kind of fruit)
'washing liquid containing red' is the wordplay.
I cannot quite see how this works, but
'red' could be 'che' (Che Guevara the Marxist revolutionary) and 'che' is found within the answer.
'liquid' could be 'lye' (I have seen 'Alkaline liquid' mean 'lye' so perhaps 'liquid' could also mean 'lye') and 'lye' is present in the leftover letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lychee that I've seen before include "Juicy Chinese fruit" , "Rough-skinned fruit" , "Litchi" , "Fruit originally from China" , "Popular Chinese fruit" .)
