Best Solvent To Remove RV Window & Roof Caulk?

For caulk, not silicone I find mineral spirits is best all round remover and plastic razor blades or sharpen the edge of an old credit card.

Remove the bulk with what ever you can use without scratching paint and such, razor knife, knife, chisel, putty knife. Then soak the remaining caulk with mineral spirits. I wet paper towels with ms and cover with plastic wrap and will tape it on walls. Let the MS do the work, then scrap with plastic and use scrubby sponge to clean up the rest.
