A number of years ago, I was forced to store my modest collection of firearms and accessories, in a dehumidified bank vault, inside a locked metal locker. I went over each and every one well, possibly over oiled them, not knowing how long it would be prior to my being able to clean and take care of them.
I used Break Free, and still do, however, some of these were not handled or cleaned for 22 years, and even break free will solidify and be difficult to remove. There was no rust or corrosion on any of them, but little things like the plunger tubes on 1911 had to be replaced, extra attention to get the solidified oil out of the cylinders of revolvers, etc. Like I said, I still use it, but any product over a long period of time will solidify. Most will not have such a storage problem, but at least I know what will work to protect my babies.
