What should be used to remove this?

Hey there smarter people than I,

I have to re-create gaskets for this sliding shower door. I've already figured that portion out using my company's laser cutter and some neoprene gasket material.

My only question that you guys might know is what would be the safest way to remove all of the existing gasket and either silicone or adhesive that is on the chrome surface. Given this is in a shower I do not want to scratch and create rust so using a scraper or a razor blades seems awfully risky. Is there anything chemical that would be chrome safe?
