Hi folks. When using citric acid on lantern parts which parts should not go in bath? Also is there a resource that tells you which parts are made of what metal. Still learning thanks.

No paint n the citric.  Brass goes in, but keep an eye on it.  You want to take it out before it starts turns pink.  Otherwise, have at it.  For Coleman, and most other lanterns, fuel system parts are brass and rest is steel.

Do not put the vent in citric, it will etch the porcelain. It will also take paint off (or at least loosen it) so no founts unless you're wanting it stripped. Brass parts can go in but only for long enough to clean them and it doesn't take very long (a few minutes if hot). Do some searching around here on forum, lots of good information to be found on material parts are made of and on using citric to clean and other methods too.

Why is there never enough time to do it right but always enough time to do it over?

When in doubt, check it out. Some frames are zinc plated, and the acid will remove the zinc long before it removes the rust. When I'm not sure, I test a drop of the acid in a place that won't be seen--under the floor of the frame, inside the collar is good. If the acid foams, you have a reactive metal, likely zinc.

Whatever the flat silver paint/plating on the air tube of some later 200As is also highly reactive and goes away FAST in acids.

Direction disks are a never-use-acid or any harsh cleaner of any kind. That silkscreen paint is very thin and sensitive. I clean mine with a little dish soap, warm water, and my fingers.
It's priceless until someone puts a price on it.

200A cages with a nickel plated air tube shouldn't be soaked for a length of time.  Citric will quickly strip the nickel finish off.   I've had no problems soaking brass parts in it.  Yes, they turn pink after a while, but a rubbing with fine steel will will bring the brass color back.

I once had a fount filled with hot citric and left it overnight with the valve in, but had forgotten to remove the F/A tube.  I couldn't believe what happened to the F/A tube overnight: nothing.  It turned pink like it had been left in there a bit but that came off with fine steel wool.  I expected to see that it had been eaten away but there was absolutely no damage.
