My balls get rusty and it's not from under use 

Living in the rainforest I only have to leave something overnight and it either rusts or gets mould on it - it really is an uphill battle..…..

I understand your problem there Mike. I used to live on Springbrook Mt. and quiet often if we had the doors & windows open the clouds would blow through the house. 
Our leather and shoes in the cupboards would always get mouldy. Droplets of water would form under the bed on the floor. I waited until we shifted off the mountain before I bought a pin.
