Green Sweep

GreenSweep is a sweeping compound that can be sprinkled on a dusty shop floor, (see metal shop), and will then allow the inhabitants to sweep the area without raising a ton of dust in the air. It doesn't have to be used every time, but then nobody seems to be sweeping with any regularity.
A 50 pound box costs about $30.
While we're at it, are there any good brooms around? Where?
