After seeing people being productive here, I went out to the garage and put the oil dry (kitty litter) into its own dedicated 5 gallon bucket properly labeled instead of a loose bag. Already I feel better about that.
I just picked up a commercial mop bucket with wringer / squeezer at the local auction house so I gave that a whirl with a new mop. Blew out the garage bay with a leaf blower (Some day I might use it for outdoor stuff, but right now it's a garage blower), swept the corners, then mopped the floor.
Everyone mops their garage floor, right? I just like being able to kneel down or sit on the floor while working on something and not come up dirty. Epoxy floors help, but only if you actually clean them.
Later, I will look at lighting options under the garage door while it's open. That cuts off a big source of light and I think I need to address that.
