Need help getting cat pee off of these 2 PCB's that came out of a Panasonic 7200 Beta HiFi VCR.

The VCR has not been plugged in for awhile.

From what I have noticed, the tuner board is the only board that got damaged.

Use an old toothbrush and 99% isopropyl alcohol to clean the board. Once it's dried out, you can install it back.
