Scrub away a needlessly fussy visual style, trendy narrative tweaks and a climax both morally repugnant and logically absurd, and there’s a tough little noir about buried transgressions coming out of the past in Renny Harlin’s lackluster thriller “Cleaner.” Too mainstream to attract genre interest, and too tangled in its character motivations to sit well with the multiplex crowd, this is a minor stain that should fade quickly and leave only faint traces in ancillary.
