I've got everything in a variety of buckets and boxes. The stuff that gets wet (immersion chillers, spoons, funnels) are in buckets. The boxes hold scales, cappers, caps, and a host of other things I've collected over the years. I also have a tool box full of odds and ends like stoppers, spices, keg parts, etc.
Hoses and brushes hang over the laundry sink. Some stuff, like hydrometers, sit on the drying rack on the dryer until the next time I use them.
Everything is sanitized before use and after use.
I should probably get a better handle on organization...
