Tunnel Wash Harewood is a car wash located along Sawyers Arms Road in Christchurch, holding a 4.6 Google rating.
A conveyor-style tunnel wash is built for drivers who want a thorough exterior clean without spending half their weekend on the driveway. The key to a good automated run is the pre-soak stage, which softens road grime and bug splatter before the soft-cloth rollers or high-pressure arches make contact with the clear coat. An underbody blast is particularly useful across Canterbury to rinse away gravel dust, winter road grit, and rural mud that quietly gathers in wheel arches. Regulars tend to vacuum the footwells first, pull their mirrors in, and check that windows are wound up tight before rolling onto the track.
It provides a quick, practical stop for motorists looking to keep their vehicle tidy while passing through the area.
