Homebrew PCBs

I think I have it, the darn cartridges are empty, incredible.  :(

I started cleaning the insides of the black/yellow/red cartridges with LCD
cleaning wipes (MG Chemicals #8242-T).  The stubs stopped getting wet rather
quickly, and the wipes started coming out the cartridge holes nice and
clean.

For some reason, both Epson and SSC utilities think there is red and yellow
ink even if the cartridges are bone dry.  The ink keeps coming out the blue
cartridge, that one continues to work well, but the printer can't work just
in blue, so that's useless.

Since I'm not able to order on credit card until my daughter empties her
card (that might take a year), I'm going to buy replacement cartridges from
Staples and start fresh.  Not much else I can do at this point, at least I'm
guaranteed 'some' results if I buy original replacements (start with black
for now, I guess).   I'd like to get the heads wet as quickly as possible
before whatever deposit is in there hardens even more.

Update on the situation:

The black cartridge registers as totally empty, both using the Epson utility
and that Russian SSC utility.

No more black is getting on the paper, BUT, the cartidge continues to 'wet'
that plastic injector at the bottom of the chariot.  Everytime I remove the
cartridge, that stub is very wet, much more so than blue, and blue prints
nicely.

So I know I have black ink, this is much more than a matter of cleaning the
print heads from the bottom.  I believe I should clean them more
'aggressively' by the top.  It's not a matter of ink having a hard time
getting out, it's a matter of ink not getting in at all.  This is where I
need advice from experienced players.

1. Can I just dap a drop of IPA 99% onto that stub?

2. How is that ink fed into that stub, gravity?

3. Can I use light air spray to increase penetration?

I looked around at removing that chariot for a complete soak, and that
doesn't look like an option.
