Hello,

I recently was replacing an analog stick in my ps5 dualsense. I used the cheapest solder paste for the job, thats sticky and brown.

While the repair was a success i can't seem to get rid of all the brown shit it left on the PCB. I scrubbed it with IPA and toothbrush, and a brush. I even applied some heat but its always there. Cant seem to collect any more of it.

I already ordered amtech flux, and dont want to use that paste anymore, but it would be awesome if I could make my PCB great again.

Any ideas you guys might give me? I might add I'm like 2 years into microsoldering and I make numerous mistakes. Im no expert on this.

Thank you
