A good brush for rims gaps. Where I used fingers have almost broke my Anyway, now the brush is used. For the inner surface of the rim but not, or only partially suitable. For the right brush or a rim glove is significantly better. Here it is today - after the 3rd set of clean summer rims / after - the foam core torn or cracked. When cleaning the brush then also the core has detached from the stalk. That should not happen after 3 weeks and 12 wheels.
