Cleaning mouse urine from PCB

Nov 28, 2007 10 Replies

Had an unfortunate incident of finding a dead, electrocuted mouse in electronic gear tonight, more unfortunately before it died, it managed to consume a large part of an antistatic bag, and left piss on several small areas of a PCB, including under some surface mount components, and around and under an 8 pin surface mount IC.



The PCB still works, so its worth a shot at cleaning it up, before its too late



Before I risk making the matter worse, can anyone suggest a cleaning method to get rid of as much of the residue as possible without damage, and minimising future damage.


Maybe some gentle washing with warm distilled water and cotton buds, then making sure it's completely dry before re-applying power. I've cleaned contaminated boards that way and I don't remember having any problems afterward.

** Warm water and some dish washing liquid is all you need to take the * Micky * out of that mouse residue.

Gentle scrubbing with a tooth brush will help, then rinse with lotsa clean, warm water.

Dry with some warm air from a hair dryer.

No Daffy idea at all.

The only way is by gently licking the affected area.

Isopropyl alchohol works good. Make sure it is 99% as it leaves no residue.

Seriously, mouse urine contains acid. Neutralise with mild alkaline (washing soda solution) and then wash with distilled water all allow to dry. All while unenergised of course.

Are you sure that won't dissolve any plastic/insulation?

Oh, and un powered! That explains the sizzling sensation...
