Plans to put backstreet cleaner first (6)
I believe the answer is:
charts
'plans' is the definition.
(charting is a kind of planning)
'backstreet cleaner first' is the wordplay.
'backstreet' becomes 'ts' ('st' backwards).
'cleaner' becomes 'char' (char can mean a cleaner).
'first' says to put letters next to each other.
'ts' put after 'char' is 'CHARTS'.
'to put' acts as a link.
(Other definitions for charts that I've seen before include "Maps for captains" , "Blueprints" , "Maps; plans" , "Sheets of tables, graphs or diagrams" , "Maps to assist navigation by air or sea" .)
