If you run a shop on Bickley High Street, cleaning is never just about looking tidy for five minutes.

If you're moving out of a flat on Bickley Park Road, the final clean can feel like one more thing on a very long list.

If you live near Bickley Station, you probably know the rhythm of the area: commuters in the morning, muddy shoes after a wet walk, and the odd splash of tea or dinner getting where it shouldn't.
