Slop snarfing

Hi, sorry for extremely late reply. Ultrasonic should not destroy good solders. Weak, bad solders might give up. Techyes city had a video on it on youtube a while back.

Disassemble. Use distilled water and a suitable sized ultrasonic cleaner, with one component at a time. Air dry with clean compressed air, canned not compressor. Leave it to dry for atleast a day after. Reassemble, fingers crossed.
