Staining on metal following hand wash

[dc644561]

Hi All - Had my car washed today at the local hand wash but about 6 hours later I noticed that there appears to be staining across the black metal/material that lines the windows. Check out the pictures! I'm wondering if perhaps the hand car wash used some type of chemicals and didn't properly rinse. Does anyone know what might have caused this, and what would you do in this situation!? Thanks all

It's discoloration due to car wash soap. Lots of other pics and solutions here.

MY Door Trim Discoloration

I have a 10 week old MY, and the black trim is starting to show rainbows and almost a rust in some places. Assuming this is from chemicals in a touchless car wash. Thoughts on restoring it, then protecting it?

Use Mr clean magic eraser to get rid of the oxidation. I could be wrong, but I am pretty sure it’s a type of wax that’s causing the aluminum door trims to oxidate like this.

I used wd40 and it seems to be working well. I did the same thing to my wife’s CRV.
