Streaks on Window after Rolling them Down

I park under a tree which is a royal pain the ass but I don't really have any better options at the moment. I have been cleaning my windows religiously but i guess some sap got on them at some point and got on the seals which means I get streaks on my window every time I roll my windows down. Best way to clean the seals? I'm thinking of just getting the window soaked with invisible glass and rolling them down/up. is there some tool for cleaning the seals? can it be wiped down with a microfiber or is the dirty seal deeper in the door?

 

Tree sap is very sticky stuff, and can be difficult to remove. I would roll down the windows and clean the inside of the window seals with micro fiber towels saturated with denatured alcohol. Stuff the towels in the slot where the window normally sits and move it back and forth a few times to disolve/remove the sap. Let the seals dry before you roll the windows up. It may not remove all of the sap, but maybe it will at least dilute it enough so it doesn't cause streaks. Personally I would't use a more powerful solvent than denatured alcohol. Anything stronger may desolve/deteriorate the window seals.

 

cleaned the seals as suggested and no streaks so far! might have to do it a few times more.

 

Clean the seals, and use some window track lube. Used to be in the RV section at Walmart. Will help the windows go up and down fast/smoother too.
