Quoted from kevinclark:yaksplat I’m using leadfree (I’ve got young kids in the house)
Buy Kester 63/37 lead solder. Lock it up in the pin cabinet when not in use. Don't eat or drink when working and wash your hands when done. No problems when used correctly.
As far as your soldering goes, add 50 degrees and a bit more dwell time.
Also when desoldering, cut components from the board first, heat leads and pull out one at a time. Then clean up the pads.
