Hello all, I have had my H-170 in my driveway for two weeks while waiting for a jib repair. While it has been there we have had a couple thunder storms and some maple tree debris has fallen into the boat, along with the droppings of some birds that look like they have been eating mulberries. Anyway here I am with stains on my boat. I have done what the owner's manual suggests up to the "you can use mineral spirits but don't leave the rag in the boat" part. Has anyone out there cleaned their boat with mineral spirits?? What experience have you had? Many thanks, John
