how to remove back to black from windows

[acrock0114]

hi guys,

the other day i bought some mothers back to black and applied it to my range rover and i some how managed to get some of it on the windows. ive tried washing it over and over again but it still wont come off. the back to black left a smear that if you try and wipe off, it just moves on to another location of the window.

thanks for all your help,
andrew

Try a quality automotive glass cleaner and a clean microfiber towel.

Or, isopropyl alcohol.
