The trimmers are on one side of the tuning gang - usually one trimmer for each stator section of the gang. The non-moving plate sections are called stators (stationary) and the rotor is the moving halves of the gang.

BEFORE un-screwing each trimmer adjusting screw, COUNT the number of turns to remove it, so it can be put back in an approximate position so it will be close to current position and compression when re-alignment is performed. Otherwise re-aligning can be more difficult.

Removing the screw should let the top/outer plate lift enough to get the micas sheet(s) out to clean and also clean the bottom and top plates before re-assembling. Also clean any residue on the bakelite or fiberboard stator brackets holding the stator plate sections in the gang frame.

Use isopropyl alcohol that does NOT contain glycerin, i. e. "rubbing" alcohol.

As far as the gang plates, I'd use a fully evaporating cleaner, isoprop comes in spray cans too, which would let you flush the rotor and stator plates. Just a couple drops of light oil on the two rotor bearing would be in order too, since the alcohol spray will remove any lubrication there as well.

You may have to un-wire and remove the gang from the chassis if you cannot access the trimmers to clean.

The gang and trimmers should clean up fine for re-alignment.
