I usually "dissolve" mine in a bucket of non-diet cola. Cheap & easy to source. The acid to damage electronics, and the sugar gums up mechanical parts.
So I don't believe the NSA are out to get me, if I did I'd want something a bit more thorough. My main "threat model" is someone picks up the drive from the trash and tries to read it.
However you're wrong about this. As we know from when capacitors and batteries leak, the acid or alkali in those can get inside chip packaging by being wicked through the leads, which will destroy them thoroughly from the inside as well.
If i found an SSD that someone incompetently attempted but failed to destroy, It would DEFINITELY make me much more curious about trying to recover data off of it.
The mild phosphoric acid in your cola beverage is nowhere near strong enough to cause corrosion inside of chip packaging, lol. I doubt that it is even enough to remove a significant quantity of the anodic plating on the chip leads to permit the base metal to be attacked.
