Love theses shelves.   We use them in the utility room and in our garage.    It is great for items that my spill because you do not have to worry about the spills damaging the shelves or just poolling on the shelves.    The spill would go to the floor (yes it will drip on to everything lower but you can wipe that off but you don’t have to worry about the wall damage if it pools next to the wall up high) .
