The plumber installed my new 2 piece shower. Only problem, the base and the walls are not anywhere near flush, which will be a huge problem for the shower surround. So, I'd like the remove the base from the wall unit, but it's silicone caulked at the bottom (like it should be). So what dissolves silicine caulk, but doesn't harm the acrylic fiberglass of the new shower? And will it be able to penetrate enough to get it apart? The flange is about an inch maybe 1.5 inches, so who knows how the caulk has squished in there....
