Gray leather with yellow coloring ?? (1 Viewer)

[BullElk]

In my '06 LX, I am consistently seeing a yellow coloring showing up in the same areas on the gray leather. It is only in middle row seats on the front edge. It appears it is where back of knees touch seat when wearing shorts. Like maybe body lotions or tanning lotions or something. But have ruled all that out. It has been cleaned and it keeps showing up.

Anyone ever had this issue? Any ideas?

Yes Ive seen it on multiple 100s, with both gray leather and tan. I came here to search for this issue. What did you use to clean it with? I cant seem to get it off.
