Metal in my chemical storage area is rusting. What's happening?

Chemical vapors are attacking the metal. Your chemical storage area is in need of ventilation. Good ventilation, even as little as one air change per hour, would dramatically reduce your corrosion problem.

For metal shelf clips the problem is probably very close by. Look for iodine, iodine solutions or concentrated acids. These are usually the culprits.

To help reduce corrosion of metal shelf clips, spray them with Krylon® spray once a year. This liquid plastic will greatly reduce the amount of corrosion.
