What tool do you use for edge cleaning?

[Kleen O' green]

That's the way the brush is molded from the manufacturer. In fact, some guys like to use the little tab as a scraper. It can be useful for chipping frozen gum from carpet with the freeze spray.

But if you don't like the tab, it can be cut off too.

I think what will be great is that Rick manufacture a ZEBRA BRUSH with at least one wheel 3inches on the inside of the brush so that the bristles be on the outside edge. I got that idea patented already Rick but you got the green light on it.
