Best type of solder paste?

I am having trouble reballing my ic’s because the no clean solder paste I use flows way too much and has a lot of messy flux residue. What is the ideal type of solder paste? Also anybody know what type of solder paste is originally used by Apple? I am considering trying lead based and/or water soluble paste to do my reballing, let me know if I’m on the right track, thanks to all replies in advance!
