I have one that sits in its own hanging basket. I have a small table next to the tray that i keep deoderiser n another sealed tub on. The litter scoop hangs under the table about half height on one of the table supports.
The litter I use is quite dry n gritty so it doesnt get that obviously dirty. I wash it every litter change when I wash the tub etc or as needed in between.
Our litter boxes are in a walk in closet, so there are shelves around all the walls. I put the scoop in an old milk bag and sit it on the shelf above the boxes.
We keep ours in a small bathroom size trashcan next to the litter box. Its perfect because we have more than one type of scoop and we can just toss the in there once were done.
currently, i keep the "in use" litter scoop wrapped in a small trash bag and placed on top of the bucket of litter. i have three litter scoops -- the "in use" one, the second scoop replaces the in use one when fall and spring come (i switch to a fresh litter box, litter mat and scoop every fall and every spring), and the third one is the spare in case one of the other two breaks.
