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.

Jeweler's pickle?

Won't the acid be a problem? While not stated, I had assumed that the fuel
tank was made of copper or brass. If you look at the last part of the cited
article it indicated that the acid pickle eats copper.
