I'm nearing the end of my LXR build and everything is progressing smoothly. I'm using a water-soluble flux solder that leaves lots of icky residue on the PCB.
Is it okay to lightly wash the PCB and scrub it with an anti-static brush while it's fully populated?
I'm worried about ruining mechanical parts like switches and encoders.
How long should I wait for it to dry before powering it up? (Starting to become eager)
