If you are organising a gathering near Windrush Square, the cleaning plan is not just a tidy-up note at the end of a spreadsheet. It is part of the event itself.

If you live in a SW2 flat near Coldharbour Lane, you already know the small stuff matters: the dining chair that picks up daily grime, the sofa arm that slowly darkens, the footstool that seems to attract every spill going.

If you run a shop in Brixton Market, you already know the floor does more than sit there and look pretty.
