How to clean skis DIY

So I got a call from some folks who have a rental house up near Blackhawk. Several years ago they had acquired a bunch of skis from a rental shop that was going out of business. They decided to build a ski fence. They only used about half of the skis so they left the remaining skis sitting under a tree, in the forest, for a few years. They gave me a holler and said I could have them if I wanted to come pick them up…sure why not!! When I picked up the skis I found that they were covered in mud and pine needles. I hit the carwash on the way home.

P.S.
This is the reason why you never use the scrub brush at the DIY car wash. You just never know who was there before you and what they were doing!!!
