Among the casualties were several towels, which I used to sop up as much detergent as possible before tossing them into the wash. Others I lay on the floor so that I could navigate the messy terrain without sliding through it, and before long everything was picked up, rinsed off, or taking a cycle through the washing machine. Cleaning the soap off the floor was a bit tedious, but manageable.
Next stop, Home Depot for new shelves and better brackets! Ken got those installed in good time, and I put things back where they belonged. We added a second shelf to the mix--in part to relieve one shelf of holding too much weight, but also to get some less-often-used items out of prime storage space elsewhere in our "utility room." Ah, there's nothing like the feeling of newly opened space, and a sense of order.
