Had my car rust proofed. It's as greasy as a butter ball! I've washed it and cleaned the windows multiple times. When ever I roll the windows up there are fresh streaks of oil on the panes. I'm guessing the rust proofing substance has saturated the felt like substance in the window slots. What's a safe way to clean them? I was thinking of some mild soap and water. I'll wrap a damp micro fiber towel over a spatula and gently run it through the slot. I'll follow it up with a wet towel rinse. I need to cut the oil but I don't want to damage the sweeper material in the window slots.
Next time I take the car to get rust proofed, I'm going to put masking tape over the bottom window edges.
