Appeals for a cleaner manuscript (6)
I believe the answer is:
charms
'appeals' is the definition.
('charm' can be a synonym of 'appeal')
'a cleaner manuscript' is the wordplay.
'a cleaner' becomes 'char' (charwoman is a type of cleaner).
'manuscript' becomes 'ms' (abbreviation for manuscript).
'char'+'ms'='CHARMS'
'for' acts as a link.
(Other definitions for charms that I've seen before include "Delights" , "Talismans" , "Amulets; entrances" , "Enchants" , "''Music hath . . . . . . to soothe a savage breast''" .)
