(I’ve always used multicore to date, no issues, but was wondering about trying out some Kester)

I recently switched over to kester 331 63/37 and I love it, the boards gets super clean with simply some tap and di water. My ocd can't handle flux residue and spatter all over the place so this stuff is a life saver, no more trying to scrub of no-clean flux with heaps of ipa.
Use multicore 60/40 crystal 502 since I have a huge roll for mechanical and non-washable parts.

There's your problem... "no clean" flux is not meant to be cleaned, and certainly not with IPA. If it really needs to be cleaned you need a Kester-specified saponifier or cleaning agent, and you need to clean extremely well or you just spread the residue all over board. IPA will not do the job and will leave all sorts of nasty residue.

Yes I'm aware of that, all though the IPA cleansing worked perfectly fine since I always used IPA+kimwipes to get rid of all the residue.However it takes alot longer then simply rinsing it with water hence the change to Kester 331, I'd rather use a solder which I can clean up the flux with water/di-water without having to buy an additional chemical just for cleaning.
