Just noticed that there are white marks on the rubber around my windows. Just got the truck and not sure what it is. It almost looks like there was liquid wax on the roof and it ran down onto the rubber around the windows. Any suggestions to get it off ?

 

I had same issue on my new truck. Still need to buy some back to black product to try or will try my Collinite 845 wax first.

 

I know this sounds crazy but peanut butter removes dried wax on trim. My previous tenant was a professional auto detailer and she told me that's what she uses. I tried it and it works.

You can also use isoprpyl rubbing alcohol. Either one should work

 

I have a 2011 same thing. I thought it was just me. Gonna try the peanut butter trick. Thanks

 

I use meguirs cleaner/wax. First time you use it turns your rag black as coal. But it cleans and seals the rubber great and removes any marks. Been doing it on my mustang for years. Once a year is plenty.

 

Thanks, I will give it a try !!

 

Wow. Glad I am not the only one. Will give these ideas a try

 

I tried alcohol and meg cleaner/wax on mine and it didn't come off so when I took my truck in to get the roof repainted I asked if they could try to remove it and they ended up replacing the entire seal. So if you can't clean it try to warranty it

 

Had same issue ... Used the baseboard / trim cleaner I already had and it seemed to do the trick. Dealer looked at the other new F150's on their lot and all have same thing. They were told by Ford that this is "normal" and would go away after a while. Something to do with the assembly process.

 

That's what she said!! I used invisible glass, worked for me.
