Just to update, I did bring the soap through FLL tonight. I made sure I packed it away from my phone charger & ipod, the only electronics I traveled with. It didn't trigger a bag check. A TSA lady did run off with my shoes before I could put them back on and swabbed them. I've never had that happen before, but they seemed to be swabbing random items that were loose in bins. Cellphones, shoes, etc. They must've been overstaffed or something.
