This appears to be the simplest method for removing large numbers of components. Someone more experienced may inform us of any stupidity relating to this idea. Couldn't find any other info relating to doing this, didn't spend hours looking.
Dump your populated boards in a bucket, add 50/50 hydrochloric acid / water to cover the boards.
Sit back and relax, for 3 days, without breathing any fumes. Do this outside.
The solder will be 'one of the first things' to get attacked and may leave a sticky mess all over everything. Possibly causing other problems down the line. This was attempted with old leaded components, not any premium silver based junk.
Pour off and keep the acid, when you can see that the solder blobs have been removed, it should no longer be fizzing at any great rate either.
Wash everything down with hot water and keep all the juices, they may contain something useful, or at the very least be completely toxic and corrosive.
I have only tested this out on SDRAM sticks so far. Chips and other SMD components rubbed right off.
