I think I got there in time! The Varta battery on this 486 motherboard I recently added to the collection already started foaming, but I don't think any of it got on the PCB yet.

Spare parts delivered and soldered back to the board.
Cleaned and reseated the socketed ICs...
...and slowly turned the power switch 😉

I always start to get out the battery as fast as possible and have a first clean with soapy water.
I avoid chemicals (like acid) for neutralization because we don't have controlled reaction conditions on the motherboard.
