I've bought a dehumidifier for my workshop in hopes of keeping the humidity levels under control and reduce rusting of cast iron surfaces. Planning to plumb it to a permanent drain so it can run unattended. So far, I've been surprised by the amount of water pulled from the air in just the first few days it's been running.
What's a "reasonable" humidity level to set the dehumidifer at, given I'm in the hot and muggy midwest? Need to find the balance between rusty surfaces and a dehumidifier running 24/7 all summer long fighting to reach a level that's not practical...
