Climbing up into my hang-on and about 7 feet below where the lifeline is looped around the tree, there was about 2 feet of pine pitch on one side of the line I didn't see so I ran the prusik knot right into it. Needless to say, it gummed up pretty bad. I was able to get onto the stand manually loosen the prusik and get it above the pitch and to a height where it works to hold me if I would have slipped. but now it is stuck at the top turning it into basically a 20ft tree strap. Any secret concotions or detergents that will clean the pitch off primarily the lifeline. I have an extra prusik I can use. or am I going to have to cut it shorter and make it into a 13ft lifeline.
I would just suggest just water. Although I don't know about fabric, at my place of work we used to use pine sap mixed with water to put on gravel roads for dust suppression purposes. Worked good until it rained and then the rain would make is soluble and then it would get all over your vehicle. To get it off we used cold water and not warm as the warm water tended to smear it.
rubbing alcohol removes pine sap, then wash with your scent prevent detergent of choice to remove the alcohol smell
Turtle wax makes a bug and tar remover. Works awesome on tree sap. Doesn't smell bad, either, although I would definitely put your rope in a delicate garment bag (like $2 at Walmart) and wash it in scent killer soap afterwards. But when you factor in the cost of he turtle wax, the soap, garment bag, and time spent getting the stuff out, you may figure it's worth trashing and buying a new one. Up to you.
