I've been looking for Jig-a-loo because a tradesman used it to lubricate our overhead door and it did a good job.
But I'm very wary of nano-particles. They sometimes have quite a different toxicity from the substance they're made from, so that familiar and known to be safe substances can suddenly become toxic. One issue is the massive increase in surface area for very small particles. Because of their size, they also have the potential to enter the body through unusual routes and even enter the bloodstream. And for those who care about the environment they're a major threat.
So there'll be no Jig-a-loo on my lubricants shelf, at least not while they contain nano-particles.
