A140 corridor

The A140 between Norwich and Ipswich is one of the busiest single-carriageway commuting routes in East Anglia. Cars on that road pick up road film, iron fallout and pollen quickly — and it shows on any darker paint within a week.

Coastal and Broads dust

Norfolk drivers also deal with the sandy dust from the Broads roads and salt spray from the coastal fringe. Both need proper pH-neutral washing, not a rollover automatic.
