Just noticed this in the Owners manual (pg 6-10):

Caution When washing the inside rear window, use a soft cloth dampened in lukewarm water, gently wiping the antenna lines. Use of glass cleaning products could damage the antenna.

Who knew?

 

Did you know that they could also damage the antenna by not applying window tint properly?

 

Yea I dont use jack on my in side back window. Just a dry cloth.

 

That wont work forever.

 

Yup, this is not a well known fact but then not many people bother to read the owners manual!!!!

I did know 'cause I always read the manual:D
this is a reason why I won't tint my car I have to tint only the side windows and not the back one, it wouldn't look nice, IMO...

oh, and I clean it very rarely. better be a little dirty than damaged
