Clean moon vehicle carrying uranium (7)
I believe the answer is:
launder
'clean' is the definition.
(laundering is a kind of cleaning)
'moon vehicle carrying uranium' is the wordplay.
I cannot quite understand how this works, but
'carrying' could be 'under' (something under something else may be carrying it) and 'under' is located in the answer.
The remaining letters 'la' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for launder that I've seen before include "Act illegally" , "Led a run (anag)" , "Wash and iron linen" , "Arundel (anag.)" , "Make clean again - clothes or money" .)
