Cleaning / Lubing Colt double action internals

Recently acquired a Colt OMT and wanting to know how to properly clean / lube internals. The trigger is very heavy / stiff and am wanting to make sure everything is as it should be inside.

First, I know that disassembly is not recommended. I know how to properly and correctly remove sideplate. Is there a way I can clean out and lube all the parts without further disassembly (than just removing the sideplate)? I am convinced that a good cleaning will improve the trigger. If this was a more recent gun, I would probably leave it alone. Being as how it was made over 70+ years ago, who knows what crud, or residual grease is caked onto the moving parts. While I dont mind shooting the gun in single action, it seems a shame for such a fine firearm to be at 50% capacity.

My idea (subject to change) is to spray out the inside of the internals with eezox to hopefully remove all crud and gunk. Then to gently blow out excess oil with air compressor. A light coat should still remain even with blowing it otut. Then I got some good grease from Brownells called Action Lube Plus in the mail today. I want to put this on the parts that should be greased.

First of all, is my idea of how to proceed a proper one?

Second of all, if it is, where I should I put the grease?

Kdave21, yes you should spray Eezox into the action. First, unload the revolver and remove the stocks. Next, liberally spray Eezox into every opening - up the gripframe, into the area around the hammer and the trigger (both hammer up and hammer down). The Eezox should run out of various openings, and most likely you will see brown "gunk" coming out of the revolver. I then wait for the Eezox to dry, and carefully wipe down the revolver. Eezox, when wet, is a solvent. Eezox, when dry, is a pretty good lubricant as well as rust preventative, so there is no need to apply any grease or oil. I like to finish the cleaning with one to three coats of Renaissance Wax. My guess is that blowing compressed air all over and into the revolver would hurt nothing and would speed up the process.

While the stocks are off, consider washing them in warm water using Murphy's Oil Soap, let dry, then saturate with Pledge Furnish Polish, wipe down, let dry, then apply one to three coats of Renaissance Wax (wipe on a small amount, let dry, then wipe or polish off) and finally reinstall the stocks. Make sure to use the right size hollow ground screwdriver for stock removal/installation.

This cleaning regime will clean and protect the revolver from rust, and will frequenlty make a heavy/stiff trigger operate the way a Colt trigger is supposed to operate, or a stiffly rotating cylinder rotate freely, or a tight crane made to operate properly. If something is wrong mechanically with the revolver, of course a cleaning and lubrication regime will not fix the problem.
