Chalking

Any suggestions on how to remove cracking chalking along some molding on my Sundance? Would heating the old chalk make it come off easier or would I end up with a gooey mess? Thanks

Are you asking about removing the factory applied caulk as it deteriorates? If so, a plastic putty knife helps. Some of mine is solvent based, so it can be cleaned up good with a little mineral spirits after the scraping. The rest was silicone, and scraping is the only thing that I know of. I have recaulked most of mine.
