Get soaked by rain out in China (8)
I believe the answer is:
marinate
'get soaked' is the definition.
(I've seen this before)
'rain out in china' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'in' indicates putting letters inside.
'china' becomes 'mate' ('China plate' is rhyming slang for 'mate').
'rain' is an anagram of 'rina'.
'rina' inserted inside 'mate' is 'MARINATE'.
'by' is the link.
(Other definitions for marinate that I've seen before include "Soak meat in seasoned liquid before cooking" , "Get soaked" , "Soak meat in a sauce" , "Steep before cooking" , "Soak food in flavoured liquid before cooking" .)
