I bought a plastic stir paddle to aerate my wort, it has an aluminum shaft and after being the StarSan for about 2 hours, the shaft is now black. It has a metallic smell to it.
Can/should I clean it off. If so with what
Will it hurt anything
If I can't ride it... 1997 Goldwing
If I can't shoot it... PX4 Storm, Browning Buckmark, S&W 357, Ruger 10-22
or drink it... my Homebrew
