    Cleaning up capacitor leakage

    I'm doing some OGXbox refurbs and the clock capacitors (PowerStor Aerogel) notoriously leak all over the board. I'm not sure what you call the electrolytic fluid which comes out and gets all over the circuit board, but I would like to know the best process for cleaning it up. Should I hit it with vinegar or isopropyl? Or both? Or something else?

      99% IPA or Acetone. Depending on how stubborn it is.

          be carefull with acetone, you can take the markings off some parts with it

            Don't forget try clean water too...especially since failed capacitors tend to use aqueous (i.e. water) electrolytes and water will dissolve it once more.

              I would recommend cleaning using acetic acid if it leaked on the board.
              Every time I do I can see bubbles and hear fizzing as I put it on the areas with leaked electrolyte, so it does a chemical reaction that much better removes it.
              Of course you need to clean very thoroughly after with IPA as acetic acid will otherwise do damage on its own...

              Here an example of it in action:
