Hmm. The universal solvent is awfully handy, and yes, it did do the job, but I suspect I could make things a little easier for myself by using a more task-specific solvent the next time.
Note to self: experiment with acetic acid next time. It'd be rather convenient if it turns out to do the trick.
Argh. Unlike yesterday, I woke today already having a headache. Possibly due to inability to fall asleep last night once I hit the level of tiredness that made sleep a really good idea (i.e. tired enough to -- apparently mistakenly -- believe that I could fall asleep and too tired to continue making progress on what I'd been working on) and my additional inability to remain asleep long enough to really do me good. Feh. Let's see how effective medication will be today.
