Wipe it down with Guaro. I'm not kidding. We were setting camp in the Nicoya Peninsula, cutting small limbs smaller than the wrist from a ficus tree. Next thing we knew we had sticky white goo all over everything. The only thing we had that resembled a solvent was kerosene and guaro, that is without siphoning fuel from the vehicle. Kerosene stinks and hangs around a long time. Although it was a hard sell, I convinced the others to crack open our sole bottle of guaro, promising to use it sparingly. It worked.
That's the only time I've needed to get ficus goo off my gear. Hope this helps. Pura vida.
