I've used regular dustpans to scoop up substrate while cleaning out enclosures before, whether you want to use the brush or not is up to you--I never did. I think they're easier since they're wide and pick up a lot at a time, as opposed to litter scoops. As for leftover scraps in the corners, a shop vac is probably a good idea unless you can pick them up with a wet paper towel (easier to do with dry eco earth than mulch).

I don't know anything about hardware either I just use dumb household objects.
