Interview presentation on any topic

I've been asked to an interview and to give a presentation on any topic.

I'm planing on doing a presentation on the technique and applications I do in my current role. I have presentations which I have given to prospective customers in the past but am unsure whether is it OK to give this.

Is it best to remove all the company badging and logos etc and make it generic or leave it specific?

I don't want to look like I've not put any effort in and just borrowed a presentation belonging to my company, but on the other hand I do want it to look professional.

Help!
