I have found that soaking it for several hours, overnight if possible, in a bowl or container with De-Solvit or Goo-Gone is the only way to get most of it out. I don't like to do this too often. If it's just one small area, you might put some solvent in a small container like a pill bottle and submerge just the affected area - just stuff it in with your finger and wad up as necessary to keep it soaking.
