Does anyone else have round plunger marks on the back window? On my 2006 F150 XL the back glass has two round marks that appear to be from some suction cups at the factory used to install the back glass. I have cleaned the glass repeatedly with windex and other cleaners and soaps but the marks are still there. They are hard to notice when dry but when the glass gets wet the circles stick out like a sore thumb and dust also collects on them. It is not a big deal, I just wondered if anyone else has noticed this and figured out away to clean the residue from the suckers off.

 

Yea, I got'em too, I Even tried this glass polish, but they are still there. Funny thing is, tonight I washed the truck and I saw them and said " I wonder if anyone else has them"

I have never seen them. You all have the slider, or the fixed glass?

 

I have the fixed glass. The marks look like a giant toilet plunger was poked on the glass, one on the left and one on the right.

 

I've got 'em, also... I tried cleaning the glass, no luck in removing them. I only see 'em when the sunlight hits the glass a certain way.

I have fixed glass.

 

I have the power slider, and have never seen them.

 

Did you try straight ammonia?

 

I have the manual sliding and don't have them

 

I have them too- I also had some written text on the back window of my '99 Ranger back in the day, and I couldn't get "13PR" to stop 'poltergeisting' itself back into the dew or fog for the three years I owned it! Yet the argent paint will flake off the wheels... Hmmm...

 

I have them on my XLT aswell, seems like it's only on the fixed glass trucks.

 

seems to me, someone is trying to break into the trucks with the fixed back window. Use a plunger and pull out the window. JMO

 

I just realized that just a few days ago what the suction cup marks were. I thought my little brother was messing around with one of his toys and put some marks on my truck. I guess I was wrong. Poltergiesting suction cup marks from the factory. Maybee I can write a book .

I got 'em too. Fixed glass

 

Try a single edge razor and windex (or another soapy substitute) the area MUST stay slick while using the razor... otherwise... you'll end up with scratches....
