In your experience, what works the best for removing silicone caulk?

A 2013 rig shouldn't have silicone caulking on it anywhere unless it's been added after the fact by yourself or someone else. Removing it successfully is one of several reasons silicone caulking shouldn't be used on the exterior of any recreational vehicle, the stuff is darned near impossible to get rid of and tougher still to get proper caulk to stick the surface that previously had silicone applied to it. :M

The silicone is on a 1972 travel trailer (painted aluminum) we bought. We want to recaulk everything.
