Silicone.

Just what is in your imagination about this stuff?

It's a type of oil, you know, just not a mineral, animal, or vegetable oil.
Certainly it attracts dirt. And if you don't have any residue of it, then
what exactly is the point?

Many "silicone" sprays are 99 percent mineral spirits and other hydrocarbon
stuff with a whiff of actual silicone oil. That's why it doesn't attract
dirt or leave a residue: it just evaporates after making you feel better.
