EPSON PX730WD: Head Cleaning Fluid Options for Self-restarting Cartridges & Unclogging LC/LM Heads

WELCOME to forum users elektroda.pl
Recently I bought a used Epson PX730WD printer and at the beginning it was OK, but when I bought self-restarting cartridges and replaceable inks for aliexpres, two heads got stuck (LC and LM) and now if I would like to unclog them this model liquid is it enough that it will be only for EPSON printers?
I live in France and I found such a liquid for regenerating EPSON jet d'encre heads.

Thank you in advance for your help.
And one more small question, can I clean the sponges on the guide under the head (see photo red arrows) and how to do it, pour cleaning liquid there, head and then drain with a paper towel?
And whether the rollers (photo green arrows) of paper feeding can also be cleaned because with a dense print, e.g. graphics, you can often see black spots.

and black spots on the printout.

I will add that if I set the printout in a smaller contrast, there are no stains but the image is less sharp.

So any liquid that is to clean the printhead will be OK?
Did I hail the moon with this question?

Epson inkjet fluid will be ok, you need to prime it with a cleaning station and then drive in an ambulance and leave it for 3.4 days if the dryness is greater, you need to do it again until the head is unclogged. Yes, these sponges can be drained with toilet paper, but it is not they that can dirty the tart, only those plastics that hold it, it is possible that they are stained with ink and have contact with the paper. Rollers are cleaned by passing empty pages and the paper will clean itself. But it is possible that these stains are for the reason that it is leaking from the head.

So not every liquid just like that for EPSON printers.
I just bought something special for EPSON:

This cleaning station is the square on the right side of the printer where the carriage park for head cleaning?
Instead of pumping the fluid with a plunger directly into the holes where the cartridges come in, can such a maneuver damage the head, because it would probably be faster than soaking?
Thanks for the help.

Exactly.
You can also pump but be careful not to flood the electronics because it can be on the printer. The flooding method is safer but needs more time,
The fluid should be ok.

And what should I do to make the ambulance park there in this square?
Activate the head cleaning program and unplug the power cord during cleaning?
Because the head probably lowers to this (tray) square only when it performs cleaning and normally it is a little higher and even if the tray is flooded, the head will not reach the level of flooding, am I wrong?

There should be a rack next to the head and on the other side also a larger one, turning one of them towards each other the cleaning station will lower and the carriage with the head will be unlocked. Then flood the square, drive the head and turn the other way, then the station will rise and reach for the head.

For me, the matter is that if I want to move the carriage to the left side, when I work the printer, I pull out the power cable and then the carriage is not blocked but with the cleaning station there is a problem that if I fill it with cleaning fluid and I roll over it with the ambulance, the ambulance covers it rack for lifting the cleaning station.
I did it a little differently, under the carriage along the entire length of its guide, I put paper towels covered with cleaning liquid and then as I moved the carriage to the right and left, the head rubbed on those wet paper towels, then I left the head on these paper towels for 12 hours.
The head unclogged a little but about 10% of the clogging remained so I thought I would open the printer so as to pull the head out and soak it a little better in this cleansing liquid.
I gave up pumping the head because I read on the network that EPSON heads do not like this procedure too much.
