A long kitchen plastic spoon or unvarnished wooded spoon works fine for me as I am not allergic to plastic and unfinished wood it fine. For wood you can drill a hole in the handle and my plastic spoon has a hole in the handle, I run a cord though it and have added a plastic stick-on hook in the shower to keep it handy. It's always greasy and don't want it contacting other surfaces. I can reach most of my back with my hands. It's just right in the middle between shoulder blades which is impossible to reach. I used to love the way luffa felt and used to treat myself to a massage once a month when working, but GD has changed how my skin feels. I don't enjoy being messaged on back, upper or lower, even when in remission. If I used a luffa it would feel like cat scratches. Fine elsewhere, like on feet.
