Can I get rid of unwanted glue on my car door?

There is a small line of dripped glue on my car door from where a previous owner must have tried to resecure a feature that runs along the side panels. Its just a little bit loose but even I would be happier if it was secure as it is likley to get worse over time. Apart from taking it to a garage, is there a way of removing the glue and doing the job properly, The 'feature'/piping panel is made of the same material as the car and the car is metalic baby blue and otherwise looks perfect. Thanking you in anticipation. Cat
