Grease residue along the top inside window track

[BF4Noob73]

When I bought my car new there is some kind of grease along the top edge of the window whenever I roll them down. Is there anyway to completely eliminate the grease? I recently got my car windows tinted, but the grease is still there. I hope the people who installed the film cleaned the inside of the windows thoroughly including the top where the grease it. I'm extremely annoyed at the grease.

What have you tried so far to remove the grease?

Top of my head says, using a "rag" with a little APC and shove it in the crack and clean it that way.

Sounds like you are talking about some black residue from the window seal, rather than "grease". Usually some glass cleaner and elbow grease (no pun intended) will get that off. Make sure your cleaner is safe for tinted windows since you have tint right over the top from where you'll be cleaning.
