We keep the soup stock containers my wife uses for making homemade soup, the soup stock is the seasoning for her different kinds of soup, they are plastic and screw on lids, maybe a couple cups each, we label the outside of the container with a sharpie marker and they are water tight and perfectly labeled and then we put them inside the machine somewhere till we get back to work on it again. If the parts don't fit in those we also use coffee containers, and cut holes in the sides of 2.5 gallon jugs, not cut the side off, just cut a flap in it till we're done with the project then toss them in the garbage. For hoses and wiring, garbage bags keep things together and dry, zip tie the bag's shut and put them in the cabs, otherwise, screw the bolts back in the holes as willie said. We also have colored zip ties to color code things, and of course a pocket tablet to jot down wiring diagrams and how things bolt together again, that stays with the machine and in one of the plastic containers with a screw on lid to keep it dry.
