I don't care why. I know that my Authentic KFun does not rust my clone does. Same juice. I can only guess they used a lesser grade of stainless steel.

What brand clone?

That I would believe. Ive seen it happen.
Cheap steel screws.
I dont believe a stanless steel deck rusted from e juice.
Thats alot of markup for SS screws.
