Fast Lane under-car spray
Water is sprayed up at the underside of the car.
What this stage does
The underside takes more abuse than any other part of a car, and it’s the part nobody looks at. Every wet road throws water and grit up into the wheel wells, along the rocker panels and over the brake lines, fuel lines, exhaust and suspension. From November to April that water is salt brine.
A wash that only does the sides and roof never reaches it. The under-car spray aims water upward so the salt is rinsed away instead of drying into a crust that keeps the metal damp. Full and Luxury include it. Quick doesn’t, which is fine in July and a poor trade in January.
When it matters: Any time the roads have been salted, after gravel or muddy roads, and once more when winter is over.
