If it's a carb that is going to be stored as a spare after rebuilding I inject ATF fluid into the carb bowl and use two zip loc bags for storage. ATF will eventually get through one plastic bag.
I've rebuilt and stored stored several carbs for over 10 years and they are ready to go when removed from the plastic bags.
The ATF keeps the aluminum and all gaskets ready to go, no corrosion, etc.
I'm going to see if a 50/50 mix of cleaning vinegar in the USC will clean the bit of rust off a set of steel lug nuts.
