Chip-Quik is great stuff for multi-leaded SMD components.
I don't use it on SMD components that have a small number of leads.
Those with 2 leads, I heat the leads alternately until the component has
absorbed enough heat to allow it to literally float off the pads.
Those components with leads formed so I can get a *very* thin knife
blade tip under the lead, I can start at one end and heat the pad until
the tip of my knife can lift the lead off the pad. Note that I have
sharpened my pocket knife for many years and the blade has a tip which
is more slender than the most narrow Exacto knife.
If those techniques will not work, I use Chip-Quik. The only downside
to Chip-Quik is that *all* the Chip-Quik residue and special flux must
be cleaned up or the new solder will not stick.

I really should update the Desoldering Primer to mention Chip-Quik. I've used
it to remove 100-pin TQFPs with no damage to the parts or the PCB. It's really
cool stuff.

And as a last resort, cut the leads and then clean out the bad parts and leads.
Even the best rework gal will not try to save a multi-leaded part. Too much
risk of damage to the PCB.
