I live in the rust belt and I have always sprayed down the underside of my cars once a few weeks in winter. So far this strategy has kept my car rust free until the cars are 15+ years. I am considering a hybrid Toyota Camry, I wonder for this particular car, is it safe to wash the underside like I wash a regular car? Thanks I have never owned a hybrid and hence my question .
Of course. It may be a hybrid but it’s subject to the same design requirements as any other vehicle. Meaning the whole exterior of the car is designed to get completely soaked with no issues.
