In Arlington, you should be fine with graphite powder.
Up here in MI I have found that taking General Motors' advice on lock lube is best: synthetic motor oil.
Several blustery winter mornings with the cigarette lighter, trying to keep it lit in the icy wind, alternately freezing and burning my fingers, in order to open my doors, revealed to me that the high-priced official M-B lock lube goop may work in Germany, but not here.
Graphite is a great lube; I recall using it on my VW bugs with good results in most weather. But with water + freezing temps I have learned to keep all my locks lubed with Mobil 1, in order to displace the water.
My $0.02.
Over...

I don't like using oil, any oil, in a lock cylinder. To easy to capture the brass filings and dirt, and accelerate the wear.

I use denatured alcohol, squirted in with a needle and syringe. Melts the ice, absorbs the water, and evaporates. So far this winter, I've only had to do it once; the locks stayed dry after that.

to quote my brother who is a locksmith: "graphite - we love whoever uses it, eventually the locks stop working when it dries out. Plugs up the pins in the tumbler. We spray WD40 in them and free it up then charge the customer the service fee ($25 or $30) :P :P

WD40 displaces any type of lube in the locks nay? Egro the "Water Displacement 40" name. I used that stuff in a lock mech once and NEVER again... made it worse than it was to begin with.

At any rate, went to the 24 Hr VatoZone and grabbed some $1.40 graphite... works great again!

www.corrosionx.com or Aerokroil. Either relegates WD40 to tar removal duty. RT

Reid, I am wondering if this might be true. I use the liquid graphite on the antenna mast. It works fine for about three weeks. Then, the mast will not retract all the way and another treatment is required. If the graphite was "the ticket", I would have expected it to cling to the stainless mast a bit better and provide the necessary lubrication. But, it does not.

I might just do a test with the synthetic motor oil and see how long it lasts. It's quite thick, however, and getting it to go down between the mast sections will be difficult. Maybe I'll heat it up in the microwave. :D

Brian, try a teflon spray, I have a tube of dry teflon I used on my Hirschmann POS antenna masts when they start balking. The Indy I use has some Teflon material in a spray can, I think I'll have to evaluate some of that too. Trust me, my brother was a locksmith in CO, had lots of cases where the locks just got gummed up and quit working. I told him I owned a SAAB that started having sticky locks. I had bought it new (last new car I ever bought!) and I was responsible for the graphite mess. He suggested washing it out with WD40, which I did, and it was fine afterwards!
I think motor oil is too thick, it will hold dust particles, better not mess try it! Have you any sperm oil (Whale oil!)? I would use that in a heartbeat. I had some when I worked on mil spec hardware many years ago, my tool box still smells of it! its a very fine lube oil that doesn't thicken over time.

I think I'm going to find some of that teflon spray and see how it does on the mast. If it works for the mast, I'll use it in the locks.

I've heard this problem before. When using graphite lube, the carrier dries off, leaving a film of graphite which is an excellent lubricant. I believe the problem is people who "overmaintain" their locks, spray so much graphite that eventually it cakes up and gums the works. It would probably work best is graphite lube is alternated with some other lube or washed out with alcohol before reapplication.
