Oops.

After finishing soldering my Very First model airplane fuel tank, I went
to do the last step of any soldering project -- cleaning off the flux.

Unfortunately, while I know that the flux I use yields to scrubbing with
hot soapy water, I don't know what -- if anything -- will just take it
off. I'm experimenting.
