Removing silicone caulk?
The previous owner used silicone caulk in a few places on the outside trim on the fiberglass siding :(. I've scraped, peeled, slowly and carefully used a flat razor and even gave it good cursing :M ye...

I followed that with mineral spirits, and finally, lacquer thinner. Acetone would have worked as well for a final solvent but I had the lacquer thinner at hand.
The problem is even if you remove all the visible material, there is still trace amounts there that are near impossible to remove and yes, they do interfere with most other materials bonding.
You may as well try the products listed.
3M caulk remover made a believer out of me. Applied correctly and allowed to work, it dissolved nearly all the caulk over some very thick beads of silicone. It's easier to operate a rag than a grinder, trust me.
