Very carefully, if the glass is still in the car. Water and soap will do nothing, you need a 'co-valent solvent', as you have to shift an organic residue (the glue). It's FAR better if you can remove all the glass, to prevent the mess getting on your interior trim, but you need something like white spirit (which will do the job very well), although I would start with something more gentle such as cheapest aftershave from your local discount store - it has ENOUGH alcohol in it to be useful, though you may need a couple of applications. Watch for staining on the door trims though. Can you use masking tape and newspaper inside, and plenty of old rags?

Hello
