2019 grill chrome spot corrosion

[tom3]

Posted this previously in the wrong forum. Sorry.

Anyone seen this before? Washing the Tahoe (2019) and noticed the smaller plastic chromed grill bars are starting to pit and corrode. 2 1/2 years old and 16k miles, garaged. The pieces just snap in. The basic grill looks fine, must be better stuff. Couple pictures, not real bad yet but sure won't get any better. But I'm wondering if the individual pieces can be bought without replacing the whole grill? .View attachment 360986View attachment 360987

Truck driven in the winter where they use brine or liquid salt for snow removal? Seen things like this on other forums where that's what they were upset about

Never been in snow but we've been running around Florida and lots of salty air. I do keep it clean as possible even so.

Wax my friend. Looks like hard water deposits to me.

Did wax fix your problem? I have the same thing, but over the entire grille.
