I used to be just plain "skeered" of rust. Having a LOT of metal toys, I spend a good weekend every month reviewing everything for rust and doing touchup cleaning and oiling of everything. A while back I was in the hospital for 5 months and hubby was running between work and spending time with me and doing everything around the house. So everything went almost 6 months without being drawn out of the leather or taken out from under the bed or behind the door. I settled down a couple of weeks after I returned and started in the living room working my way to the gun safe, taking each item, full stripping and check over. Cleaning out the dust on the nightstand gun/behind the door 12 gauges. I figure I should finish up the safe in another couple weeks and it will be time to start over again. Now, I just plain HATE rust! Annoying stuff. Fortunately most of the blades and guns are heavily oiled and properly stored. Just the EDCs and house guns/blades that need work. But I understand how annoying it is to remove a bit of Rust without damaging anything else. Moonw, I suggest using Scara's idea of killing the active rust first, then after the red rust is gone, Hang in there and just take your time removing the deactivated rust at least you won't have to worry about more damage while you go slow to take that off.
