The week after a monsoon storm: what to wash, and when

Every monsoon season the tunnels are quiet during the storm and full the morning after. Here is what actually needs attention.

Why it can’t wait

Storm water picks up dust, minerals and oil from the road. When it dries on a hot panel, it leaves spots that can etch the clear coat within days.

Do the underbody

Mud packs into wheel wells and frame rails and holds moisture against the metal. Every wash from Shine up includes an underbody flush for this reason.

Glass first

Mineral spots on the windshield scatter headlights at night. If they don’t rinse off, a glass polish removes them before they etch.
