Dishwasher and Calgon - Bob Pease reckons it works a treat to remove polar contaminants.

I know this is completely out of topic but I know there are some dedicated material experts among you. So please allow me to put the following question

Is there any good suggestion available on how to remove electrolytic coating resulting from leaking electrolytic capacitors from a pcb? It is not a question of good looking, the coating seems to have a real "electrical conducting" property which is absolutely bad on higher-impedance circuitry as to be found on a Tektronix TDS45A scope mainboard, where the problem is encountered. The findings so far are that the classical method with isopropanol and a brush won't work. And the internet won't give precise answers for that problem.

Any suggestion is highly appreciated!

Best regards
