I also dip my blades in alcohol. No mineral oil though, I may give it a try. Perhaps a drop or two in the alcohol jar.

No kids in the house, so I leave my razors open over night for drying.

I've only had a problem with one razor. It has been treated and stored exactly the same as the others, but has a tendency to rust near the spine., at least it looks like rust. After I cleaned it up using MAAS the second time I've used oil on it.

As this razor gets exactly the same treatment as my other razors, and it has started to rust in the same place twice, I begin to think there is something about that portion of the blade. If I hadn't had it happen, I would have a difficult time believing this could happen, but I now know it can.
