California Car Duster, "In fact, the 'dirtier' it looks, the better it works! Options

[orthobiz]

So I order the California Car Cover and the guy on the phone asks, do I want to buy one of the famous California Car Dusters? OK, so it arrives.

I didn't do my homework here 'cause I thought it would look like a giant angry cat's tail or ostrich feathers or something, but hey, 20 bucks, how wrong can I go? But this thing looks like an dangly elongated mop head with a short wooden handle.

The mop part feels greasy or treated. Sure enough, the booklet says it's treated with a special paraffin wax. And they imply it is SUPPOSED to look dirty, the DIRTIER it looks the BETTER it works. Like DIRT all of a sudden is GOOD and DUST is no longer ABRASIVE. This thing, like an oil and salt rubbed iron skilllet, gets seasoned with continued use???

The booklet goes on to say if "you feel the need to wash the 'Original' California Car Duster for any reason" you can wash it by hand. Oh yeah, the first few uses may leave streaks, but I shouldn't worry. Heck, I'm worried about scratching paint all the time.

Help me out guys. I've got less-than-concours family cars I can use this on if need be. I can even return it, but I hate returning stuff in general. Is the California Duster a godsend or is it anathema, to be loathed and avoided like the plague?
