Possibly, but I'll bet it's too coarse to get into things. Middle-east environments are likely to be well within the operating requirements for any military-hardened versions. So think: dust, dirt, dry clay, and sand.
Diatomaceous earth, and any super-fine starch that can absorb lubricants would be my best bet here. A very, very finely pulverized sand or glass might also do the job. It might also be worthwhile to see what solvents and chemicals can penetrate sealed bearings, eat wire insulation, and corrode water-resistant alloys. Heh, maybe just a jar of brake cleaner would work.
