Does Rain Actually Clean Your Car?

We’ve all said at some point:
“Why bother washing the car? It’s going to rain anyway.”

And hey, you're not wrong.

I know, I know. Coming from a car detailer that sounds silly.

But in reality if you wash your car before it rains or take it through the tunnel, car wash while it's raining. You've essentially just wasted a wash.

Let’s clear some things up and explain what rain really does to your car—and how mobile detailing from Road Hog keeps you protected year-round.

Rain Isn’t Just Water—It’s Dirty Water

Unfortunately clouds don't have britas. So all the pollution, road grime, salt, dust, and other contaminants that where in whatever liquid that evaporated into the clouds is splattering all over your car in the form of low pH rain (what does “low pH mean?)

When that rain lands on your car:

• It leaves behind mineral deposits that create hard water spots.
  
  

• It adds contamination to your paint.
  
  

• It can etch into your clear coat if not removed in time.
  
  

This is especially true for Florida’s summer storms, which often dump rain after long stretches of sun-baked dirt and mud buildup.

Rain Makes Dirty Cars Look Worse

Let's face it you probably bought your car because you like the look of it. Unfortunately if your car is already dusty or coated in pollen, rain doesn’t wash that away—it turns it into streaks and splatter. Once the water evaporates, you’re left with a blotchy, spotted mess.

And if you're relying on rain as a replacement for a car wash is like swimming in the Gulf instead of showering.

Can Rain Damage My Car?

Yes—especially Florida rain. Florida has some of the highest levels of salt in rain water in the US. That means:

• Water spots from mineral deposits can etch into the clear coat.
  
  

• Salt and sand can lead to rust or paint failure.
  
  

• Contaminated rainwater chews thru wax and ceramic coatings prematurely.
  
  

If you’ve ever noticed your car looking worse after a rainstorm than before, now you know why.

Then when should I wash it!?

Ok, ok.

Relying on rainwater is not a good car care strategy. Here’s what actually work:

• Wash after the rain ASAP

• pH neutral car soap
  

• Protective treatments like waxing or ceramic coating
  

• Glass coatings (to improve visibility in Florida downpours)
