This maybe a naive question but do you ever need to wash the underside of the Lexus and if so how do you do it on your driveway with a hose?

Just curious as it rained this week in San Diego (I know I was as shocked as you) and I was out driving in it and had to wash the car. (I usually just stop and throw my body over the hood trying to keep it dry) so now am asking the question.

Thank you.

Rain... Just rain?... No. No real need to worry about the underbody.

Here is what cars look like in the Midwest after just a 8 mile drive to work in the salt/snow.

I rather not wash the underside of the car because that can lead to more problems such as rusting the metals, nuts and bolts faster than normal. Even if you do, who gonna lay down and watch underneath your car??

That is painful to watch. I thought CA rain was bad enough to make the car dirty. Fortunately, what is shown in your picture never happens in CA.

The only time I would do that if there was an oil leak that got fixed. That hasn't happened to the Lexus. I wouldn't worry about it. I was pretty shocked it rained too, just got the car detailed! haha Good thing it's going going to rain this weekend! Detailing time!


Damn!!! Is this your primary car or do you have a "winter car". I drove in the snow once, never again! Raining in San Diego is like a bizzlard in the midwest! haha

That is my only car... Salt cleans up easily with good protection on the paint. It's no big deal really as long as you don't let it sit forever.

I snapped this quick picture yesterday after power washing my car. Water still beads nicely despite not being washed (except pressure washing) in over a month of driving in this kind of crud.

No I have an older beater car but was driving the Lexus when I was ninja attacked by the rain. Thanks for the replies on this subject.

I see that you're located in CA. Here in DC, we had ICE a couple times the past week. This resulted in a lot of sand and salt. Would you still advise not to wash the underside of the car? I plan on just taking the hose and rinsing off the sand and salt off around the wheels, wheel wells, and underside. Or should I just leave it as be?

Thanks

A rinse or pressure rinse is generally fine... overtime cars in harsh conditions will be more prone to corrosion, but in general it is not going to lead to component failure.

Yeah, if that is the case, rinsing water is better because water does not corrode metal as fast as salt does.

Man I feel bad for the cars having to go through these harsh condition in states where it is snowing.

I feel bad for the people who live in Arizona. Crazy sandstorms sometimes! I'm driving there soon too haha
