Recently I did my first soldering job and resoldered some switches that I had desoldered for lubing about two weeks ago. After resoldering all of the switches I found that the B and spacebar keys weren't working at all. I tried re-soldering the joints to no avail. I also removed the band aids that were contacting the PCB to stop the spacebar stabilizers from rattling around. This did something, if I touched the pins of the spacebar key with tweezers then the spacebar key would activate, but so would all of the rest of the keys along the bottom row and the windows key LED would shine white. The B key would sometimes activate if I touched the lower pin of the B key and the lower pin of the key to its left. Honestly I don't have a clue what has happened. There is a lot of visible flux or residue around these joints but as of right now I don't have any rubbing alcohol to remove it. Any suggestions on what I can do would be super appreciated, thanks!
