How to clean an HVLP spray gun??

Not sure where the people missed the boat here?

My Binks model 7 Spray guns I take apart, pour 1" of automotive paint stripper into the cup (aviation stripper) and put all the spray gun parts in there to soak for a half hour.

Brush on the stripper to the Spray Gun body and internal paint ports.

After all paint has lifted off after brushing with a fine paint brush, rinse off all the parts with water, and blow dry with compressed air.

Reassemble all the parts and spray lacquer thinner through the gun for the final spray test.

Pefect Spray Pattern every time. Clean as can be.

I have spray guns that are 45 years old and spray perfect patterns to this day.

Just need to strip them clean from time to time.

I definitely don't recommend soaking newer style guns. Iwata and Sata being the most common have plastic seals in them that can warp and distort when soaked in solvent. I spray about 3 cars per day and I take all of my guns apart fully after each use. I rinse them in thinner then give them a few shots of aerosol thinner. Once a week usually Fridays I pull them apart fully and brush and clean all of the parts.

As noted above I have the newest version of the plastic 3m accuspray gun. I spray almost anything through it and it works well having multiple fluid sets available.

Iwata brand guns do not require needle changes with fluid tip and air cap changes.
