I found a new use for the umbrella clips that I thought I'd share.

Instead of hanging the interior air freshener from the rear view mirror and looking kind of tacky, I've been using the umbrella clips. It works just fine (I like the vanilla scent), the freshener is less visible, and the car looks still sharp from the outside without having that pesky thing visible.

Before and after pics.

 

Maybe you could use one clip for the air freshener, and the other clip for a wheel cleaning kit...
