White streaks black leather interior

[outrag1]

Attached is a couple pictures of my 2024 Silverado with the black leather interior.  There's a couple white spots on the driver's door armrest and side of drivers seat.  We've had a lot of snow cleaning this year with spillage when the door opens which would bring some moisture to these areas.  My black Carhart coat (with the rough feeling material) also has these marks in the same area.  The spots are not wiping off with water and a cloth.  Any thoughts on what it is and how to remove?  Now that I think about it, my 2018 with the black leather interior had the same problem on the pass seat where my dog's canvas supply bag would sit.  I couldn't quickly clean that up either.

 

Thanks

I'm assuming you've taken a damp towel to it. Maybe try some automotive leather cleaner.

Ya someone elsewhere suggested chem guys leather cleaner.  I haven't tried much else besides microfiber and water yet on the new 2024.  On my older 18 I tried different chemicals I had in the cabinet and nothing seemed to work but I cared less because I was trading for the new truck and the detail department probably made it presentable to the next buyer.  

 

It just seems like the same problem on both trucks (similar or same black leather interior) and didn't know if anyone else had experienced these issues.  I don't know if the dye is coming off because both situations had a rough surface (my carhartt coat on the 24 and the canvas dog bag on the 18) rubbing against it or is it something more innocent that can be cleaned off?

 

Thanks

I came here to ask if you tried shining a black light on it, but that seems to be in poor taste now

I’ve seen moisturizers do that on arm rests and seats. Even if it appears dry a little humidity and dampness will transfer to surfaces. I used regular upholstery cleaner to remove.

Sleeveless shirts and deodorant.  Women know all about it that they talk about it in commercials on tv.
