Greasy Second Row Windows

[timf]

I just discovered after lowering the window on my driver's side falcon wing door that it left a film of grease on the outside of it when raising it back up. I'm guessing there is residue on the seal left over from manufacturing that didn't get cleaned off during detailing. Has anyone else encountered this, and what was your remedy? Hopefully it's as simple as wiping off the inside of the seal.

Had same exact issue on my X. Wiped it off using papertowel and problem solved. Hasn't returned.

Sorry to ressurect old thread, but I have the issue that when the FWD windows are opened, there’s a line left on them when closed; this happens every time.

Anyone else seen this or know the cure?
