Has anyone ever seen this?
Here's the rundown. Bought 6 Erlenmeyer flasks. I washed one with a dish washing wand that was in dish soap water (used for glasses). The medium sized wand was not long enough to reach the bottom, so I did what I could and rinsed thoroughly. Went on to the other flasks, but decided to just rinse them. When I put the 3 together I noticed that the first one had droplets of water everywhere, and almost a steamy look, or condensation on the inside except where the wand could not reach. It looks like a perfect line from the condensed tiny droplets to the clear glass. The other 2 flasks that were just rinsed slid the water down them in perfect uniform fashion, and pooled the water at the bottom, so it then could just be poured out. They dry so much faster. I cannot find what this invisible residue is in the soap whatsoever online. All I am seeing is goofy people saying soap leaves suds, or film if not rinsed (like duh). I washed/rinsed the flask in isopropyl alcohol, then rinsed with purified water. Nothing. Tried my HCL of 32% (20 baume), and NADA. What is this stuff???
