Hey everyone,
I stumbled upon a doublestrike in a stream the other day behind my church and was wondering if anyone had any tips for cleaning it before i take it down i have already soaked it in chemicals to get it clean and now i am wondering if anyone knows how i should scrub it down to remove the brown gunk. I am making a youtube video on it soon so i just wanted to know if anyone else has had this happen to them. Pictures are below.
