Caulking Removal...

I've slowly been removing and recaulking the camper one section at a time (right side, then left side). Sometimes a bit slow going yet making steady progress with removal by using mineral spirits and a rag. However, today when moving to the campers front end, I encountered a stubborn type of caulking that seemed impervious to mineral spirits...Not too sure about this latest twist, but I'm thinking that this must be silicon caulk that I'm now encountering...Question: So will mineral spirits work on silicon caulk removal - or whats up??

Thanks for Your Fine Council,

    Will any of the above methods soften or remove it??


    Well as the OP, I'm now convinced that I had encountered Proflex and not silicone...Proflex, some very ridged stuff. got most of it off with mineral spirits, a plastic putty scraper, time and elbow grease. I will say that once renewed, it does result in a superior looking appearance...

  • I once bought a used pop-up, that was in nice shape, except for the massive quantity of silicone caulk that the previous owner had slobbered over every body seam. It was a pretty grim situation until a local dealership owner told me that they typically use Coleman fuel as a silicone solvent. It worked GREAT. In places where it was too tough to just loosen up with a wet rag, I used a fuel soaked compress covered by plastic wrap. IF you are not in danger of damaging painted surfaces and decals, Coleman fuel will remove all the silicone with little effort. Good luck.

    I accidentally smeared a big patch of caulk on the side of my fiberglass trailer while replacing the exterior shower. Nooooooooooo! At first, I couldn't get it off, but what worked was some Turtle Wax and an old credit card. The wax softens the caulk, and the card gently removed it. Also what works is any citrus-based furniture polish/cleaner (I used orange oil furniture polish).
    \\I found that an ole credit card will fix almost any thing on my RV.

  • Did you try a heat gun and a scraper to remove the old caulk?
