I've never had any luck gettoing out pinesap. Designate these jeans for jobs like painting or other outdoor work. They're stained already,just let them go.

use a solvent...like paint thinner or even perhaps orange glow...soak thes tain in that if it's dried....best to get at it while it's soft.

Guess what? I used hand sanitizer and it took it all out, thanks for everyones help.

Try Laquer thinner. My son sat in tree sap in his ball pants. I forgot to buy a new pair. Told my husband (like Tim the tool time Tanner) to just paint over the stain before the game. (No time to go to store.) When I arrived at the game I noticed he did a great job. Was told he got the stain out! How, I asked, Laquer Thinner he replied. I started yelling "Don't slide" too late he slid in to home. I just knew the pants would rip right off him. Much to my amaisement they were fine. All the parents started using laquer thinner to clean their childrens pants! Works well on carpet too. We have been using it for years. Give it a try. Everyone tells my husband he should be a laquer thinner salesman. He uses it for everything. Even cleans cuts. Burns like H--- but takes the soreness out. Good luck.
