Over the winter I stupidly left my clubs in the back of a truck with a fabric bed cover during a snowstorm. The headcover of the putter was soaked and, despite my best efforts, the putter now has several spots of rust across the putter head.
Since my putter doesn't have any special finish I was wondering if anyone had techniques for removing rust that worked well for them. I don't believe the rust is major, it's mostly just discoloration, but I'd like to prevent it from becoming so.
Thanks for any help!
