vxzoc stickers and tinted windows

To get the residue off ,use the liquid as used by the double glazing firms .I got some given , its a blue coloured liquid used to get the labels/stickers off the new windows after there fitted .Works great . I also took the doors trim off both doors so I could get the residue off below the top of the door trim .I did at first to try to use thinners but it just smeared the residue all over the glass.
