This can simply be olive oil or rubbing alcohol, or you can mix together salt, warm water, and a few drops of honey.  Make sure to thoroughly wet it. Reapply the solution as needed to keep the affected area covered and damp. The pine pitch will come right off. You are now 100% clean!
Prepare a solution to use. Wet a paper or cloth towel thoroughly with the cleaning solution you chose. Wipe and scrub the solution onto the pine pitch. Wait about 5 minutes. Wash the cleaning solution off with regular soap. Congratulate yourself!
