Store in a bag with some dessicant packets. Here's a list of dessicants: [http://en.wikipedia.org/wiki/List_of_desiccants List of dessicants]. Also, can use small old refrigerator with 100 watt bulb inside, for storing rods and wires. Stays about 100 degrees. Small fan inside too. | Store in a bag with some dessicant packets.

| + | ===Frame rust=== | ||
| + | Sandblasting or dipping is best. Then, wire wheel is next-best. Can be professionally sandblasted and powder-coated for ~$250 at a good price. | ||
| + | |||
| + | Patching is usually not worthwhile, unless it's a special or valuable frame. Too easy to replace, and too much potential structural damage. Has to be done perfectly. Can be replaced with steel of the same gauge as the original frame, and welded in to place. | ||
| + | |||
| + | Where is the rust on the frame? In a critical stress area? How bad is it? | ||
| + | |||
| + | For minor surface rusting, with mostly metal showing through, it's OK to just powder-coat it. | ||

| + | ====Cleaning the inside of a boxed, open-ended frame==== | ||
| + | Blow out all the dirt, etc. Then, attach a strong towel to some strong cord. Soak the towel with rust treatment chemical, and pull it through the frame. | ||
