About to undo the damage of too much solder paste.

The simplest way works best.

Not recommended. Sucking sucks.

This one should (in theory - muahahahaha) survive longer. The piston and plunger are one part and the O-ring sits in a groove.

A cheap syringe. This one doesn't have the screw-on option for the tips, but the tapered 'thing' is the same. The tips will fit quite securely, IF the mating surfaces are clean.

The rubber seal didn't survive the repetitive pull-back of the plunger.

Now this stuff is GOOD. No smoke (at 285°C), stays on the PCB for quite a while, almost no smell at all. And it already comes with a nozzle. No need to buy another one as I did. The nozzle was horrendously overpriced at close to 2$. I totally agree with the verdict of the guys at dangerousprototypes. I did a quick test job (TQFP-32 7x7 package) and it just worked nicely. One 'helping' of flux was enough. I didn't have to constantly re-add flux like in case of the FL-88 dispenser pen.

It's not bad, but it's mostly alcohol. Leaves a white residue. I use(d) it for adding a little extra flux when the rosin core of the solder wasn't enough. Not suitable for rework, as it evaporates too quickly.

Anything is possible with good paste flux!

I don't really remember why I added the big pads when I did the layout, but I has proven to be good.
