Soldering Iron - How long to heat the pad and component leads?
Apply a liquid flux to the pad and part.
Make sure the iron is properly prepared, cleaned, and tinned. The trick is tinning the tip correctly so you have a blob of liquid solder on the tip. Plunge it ...

Cannot remove old solder
Follow up, I was able to remove all the old solder! I used wire cutters to cut it off. Low tech solution but it did separate the solder from the head sink and now I should be able to clean off the ...

Soldering iron vs hot air gun
Using a different tip may allow you to use your Hakko for the job. I have a TS-100 and it's incredible the difference it makes switching from the a regular tip to a TS-C4 tip (pictured).
If that ...

Cannot remove old solder
Don't remove the solder. Add solder. Heat the solder on the pads until it melts, then pull the capacitor pins out of the holes.
Liquid solder on the tip and the pads transfers heat from the iron to ...

What might cause these striations in this solder joint?
It looks like the vertical striations you're calling out are bridging a gap/void or some sort of contamination on the capacitor terminal (the dark area).
In this picture I've outlined what I think the ...

What might cause these striations in this solder joint?
I can see on the top picture a suspicious looking line on the top surface down the length of the capacitor approximately midway between the two sides.
The outer surface of the capacitor is also dirty ...

What might cause these striations in this solder joint?
There's some similarity (aside from the orientation of the lines) to the 'disturbed flux' photo in IPC-TM-650. Relevant since your boards will have no-clean
flux present.
Presumably a capacitor ...

What might cause these striations in this solder joint?
Those look nearly identical to the example photos of "cooling lines" in the IPC-A-610 standard (Acceptability of Electronic Assemblies). The standard does not explain why cooling lines occur,...

Soldering iron melts solder on direct contact but not when trying to solder two wires
Make sure your wires are clean and not oxidized, using flux if necessary. Solder flows towards hot metal, but it "runs away" from contaminants.
Solder is a good conductor of heat and ...

Soldering iron melts solder on direct contact but not when trying to solder two wires
Make sure there is no oxidation or other coating on the wire. In particular, magnet wire is sometimes clear or orange and looks just like wire. Just scrape the wire and see if it gets shinier, and ...

Soldering iron melts solder on direct contact but not when trying to solder two wires
There’s some confusion I think related to what it means to apply solder to hot wires. It’s pretty simple: the wires will not heat up well if the tip has no solder on it.
Apply a small blob of solder ...
