Southern tourist's solvent (8)
I believe the answer is:
stripper
'solvent' is the definition.
(a solvent might be used to strip a surface)
'southern tourist's' is the wordplay.
'southern' becomes 's' (abbreviation).
'tourist' becomes 'tripper' (tripper is a kind of tourist).
's'+'tripper'='STRIPPER'
(Other definitions for stripper that I've seen before include "exotic entertainer" , "Waterproof boot" , "Teasing dancer" , "Erotic dancer" , "Exotic dancer" .)
