If your
Casita is anything like mine, there is a LOT of silicone caulk used throughout which very often gets in the way of some of the projects. Scraping seemed to do nothing except damage the
fiberglass. Alcohol doesn't work either.
Finally I tried some
Contractor's Solvent that I had around the house and voila! the caulk came right off.
This stuff is great. If the label is to be believed, it's totally non-toxic--in fact they suggest uses for skin and hair--and it's great for removing particularly tenacious labels (like those annoying warning stickers attached throughout the Casita) as well as silicone caulk apparently. Just spray and leave it for 10 minutes or so. Come back and wipe it off with a paper towel.
