Hello fellow owners of vehicles in places with harsh winters and salt-encrusted roads. I’d like to have your thoughts on spraying the underside of your car with a hose to help remove salt, mud, and sand. When I do this to my Bronco Sport - after coming home from a car wash that includes “Undercarriage,” it pours gray and brown for minutes before the rinse water runs clean. I can see sand and salt cubes being washed out of the crevices of the wheel wells. Is it beneficial, assuming you don’t fall and break a hit doing it? Or am I wasting my time and possibly pushing the corrosion-causing muck into places it would otherwise not have gone? Comments please.
I’ve lived in the snow belt my entire life. And nobody washes the underside of a vehicle unless the car wash you go to provides the service.
And I get over 200,000 miles out of my vehicles.

We get our vehicles muddy from the dirt/gravel road and hose it off on the driveway but underneath gets washed by chance. Winters we pull into the warm garage and the snow melts. Get 18-22yrs out of our vehicles. Here’s the 16yr old orius that still Looks great once you finally give it a bath The Crv is dirt road tan because dad wanted that color. It’s original blizzard pearl paint.
I have never done it, but some people in florida with put an oscillating lawn sprinkler under their car to reduce salt buildup.
You can’t do that in Minnesota in the winter.
First, the house has to have a frost proof sillcock.
And if it does, you have get all the water out the hose once done otherwise the water will freeze and split the hose. Then you have to find a place outside to wash under the vehicle. You can’t do it in the driveway because all you’ll do is create an ice rink when you’re done.
Just not worth it!
