[s-cars] Cleaning Glass and seats

[AUDIJIM at aol.com]

The previous owner of my S4 went very heavy on the Lexerol. At the bottom of 
all the windows, I have a dried film of Lexerol, and on the seats you can see 
spots of Lexerol product that was just sprayed on and left to dry. Aside from 
scrapping, is there a product that will cut through it? I have tried your 
typical glass cleaner and then went with an ethyl alcohol, then tried MEK (methyl 
ethyl keytone) and it is still there. Maybe I need to get the razors out and 
start scrapping? I haven't tried anything as yet for the seats. Any BTDT?
